[AUDIO Only] Office Hours LIVE Ep 29: Input variables, irrigation, lights, EC, VPD

0:00:00.080,0:00:05.440 all right it's thursday that means it's time  for AROYA Office Hours hi welcome everybody 0:00:05.440,0:00:09.760 a couple reminders before we get started this  hour is your chance to hear from the experts 0:00:09.760,0:00:13.680 get answers in real time about data you're  seeing with your grow and share cultivation 0:00:13.680,0:00:18.800 tips and tricks with tricks with other growers  in this exciting industry we thank everybody in 0:00:18.800,0:00:22.560 advance for not using this time for things  like airing policy or industry grievances 0:00:22.560,0:00:27.040 or asking about AROYA pricing although please do  book a demo so we can talk about that goodness 0:00:27.040,0:00:32.080 my name is Kaisha i will be your moderator today  if you have any questions feel free to type them 0:00:32.080,0:00:35.520 in the chat at any time if your questions  selected we'll ask you to unmute yourself 0:00:35.520,0:00:41.040 so you can go ahead and ask it and for folks who  are asking for the first time alive today you can 0:00:41.040,0:00:46.400 win an AROYA hat we're going to limit that to u.s  residents only one hat per household plus we are 0:00:46.400,0:00:51.200 raffling off one of our limited edition abroad  t-shirts if you just post your email address 0:00:51.200,0:00:56.960 in the chat that's going to get you entered for  your chance to win how's it going seth and jason 0:00:57.600,0:01:04.400 pretty good staying warm excellent good to see  you guys are you ready for our first question 0:01:05.520,0:01:11.360 sure yeah awesome okay it comes from our friends  at river city growers they wrote in what types 0:01:11.360,0:01:15.680 of readings are you looking for with plant  measurements and on what days of flower would 0:01:15.680,0:01:21.200 you recommend they be taken these questions lead  right directly into our theme for the week which 0:01:21.200,0:01:26.240 is manual readings and sensor values so seth  and jason how about we start with an overview 0:01:26.240,0:01:30.640 yeah yeah let's just uh do a little screen  share here and we'll kind of look at a 0:01:30.640,0:01:35.680 little AROYA view and kind of the uh manual  reading inputs that we currently look at 0:01:37.600,0:01:42.000 now that the list is pretty deep there but there  are a few key ones that you want to look at 0:01:42.000,0:01:48.160 um typically you know as a grower we should  be taking our feed ec feed ph runoff ec and 0:01:48.160,0:01:53.440 runoff ph on a pretty pretty much daily basis  if we're being responsible so this is a great 0:01:53.440,0:01:58.080 spot to enter some of those manual reads right  directly on your phone without having to pull out 0:01:58.080,0:02:02.400 a notebook or a binder or write on a spreadsheet  and then go later enter that into the computer 0:02:03.600,0:02:08.880 but some of these are quite important one that  i really like to look at in terms of you know 0:02:09.680,0:02:14.400 physical measurements we think of measuring is  plant height we want to really track our plants 0:02:14.400,0:02:18.960 stretch throughout early generative and really  determine when that plant stops stretching and 0:02:18.960,0:02:26.160 naturally has rolled over into its reproductive  phase you know if we try to implement some of 0:02:26.160,0:02:30.080 our steering strategies at the wrong time that  can have some pretty detrimental effects not 0:02:30.080,0:02:34.480 so much to plant health but to our desired  outcome which is both quality and quantity 0:02:35.600,0:02:39.520 using these tools wrong can kind of lead us in  the wrong direction or just not get you know 0:02:39.520,0:02:45.280 that yield increase we're looking for so really  learning to time it based on plant height node 0:02:45.280,0:02:50.400 spacing and even taking stem diameter about every  other day through stretch is pretty good you know 0:02:50.400,0:02:56.480 that's not so tight that it's going to be a huge  pain to go take but it's going to be close enough 0:02:56.480,0:03:02.800 that the most we could miss that stop is by  one day which is totally acceptable yeah so for 0:03:02.800,0:03:07.680 plant height i think one of the most critical  ones that's going to help you time out your growth 0:03:07.680,0:03:12.880 cycles especially when you start just tailor per  strain and that's looking at that plant height 0:03:12.880,0:03:20.000 right when you go from your 18 6 veg light cycle  to that 12 12 and you begin some rooting in and 0:03:20.000,0:03:26.160 maybe even some generative steering at that  point so definitely absolutely at the end of 0:03:26.160,0:03:32.080 edge get that that plant height in there and then  compare that to how you grew throughout the cycle 0:03:32.080,0:03:37.920 what that stretching looked like throughout  your generative and then did we get the right 0:03:37.920,0:03:44.480 size plant that we were looking for so especially  for like two or three tier growers with the leds 0:03:44.480,0:03:50.240 a lot of times those plants start stretching up in  through the led lights and anything above those is 0:03:50.240,0:03:55.600 obviously going to lose quality and quantity so  maybe you can shorten up your veg time a little 0:03:55.600,0:04:00.720 bit which is always desired to get a little bit  more a little bit more cycles in through there 0:04:00.720,0:04:06.640 and or you know if your plants didn't quite end up  with enough uh vegetative stems and structure to 0:04:06.640,0:04:11.600 them uh or true veg you know maybe grow that  strain just a little bit taller before you 0:04:11.600,0:04:17.360 run into a 1212 and flip for generative yeah i  mean you know stream to strain a lot of people 0:04:17.360,0:04:21.760 have been surprised especially in the multi-tier  grows how small you really can flip a plant to try 0:04:21.760,0:04:26.400 to keep it inside that height range and you know  once we switch over to that commercial setting 0:04:27.360,0:04:32.560 we really don't want to be touching the plant so  that is super crucial really to dial that plant 0:04:32.560,0:04:37.360 height coming in because if i've only got four and  a half or five and a half feet overhead my plant 0:04:37.360,0:04:42.400 height needs to be dialed and now that i've put  you know all of my plants on this shelving system 0:04:43.680,0:04:47.120 it's more work to get to an individual  plant so i really want to minimize the 0:04:47.120,0:04:51.040 times that i have to go in and train tie  the plant down or do anything like that 0:04:52.080,0:04:56.000 and when i say it's surprising on some  strains if you're used to a traditional setup 0:04:56.000,0:04:59.360 with not necessarily unlimited but let's  say at least eight feet of overhead height 0:05:00.400,0:05:04.720 you might be surprised when you find that you're  flipping plants that are you know 12 inches or 0:05:04.720,0:05:10.720 less that's where it really comes in and you know  crop registration is key to tracking that because 0:05:11.360,0:05:14.880 i said a bunch of times and i'll say it again  once you have the volume of plants that you 0:05:14.880,0:05:19.200 have going through the average commercial  facility it becomes very difficult to keep 0:05:19.200,0:05:24.240 track of it just through observation you know at  any given time you might have the same strain in 0:05:24.240,0:05:28.080 every single phase of its life in your facility  and as cool as that sounds to go look at 0:05:28.640,0:05:31.600 at the point that you have that many rooms  you might not have time to just go stare at 0:05:31.600,0:05:35.200 the plants and think about it for hours on  end every day so you've got to really find a 0:05:36.240,0:05:42.720 a system that relies on quantified measurements  to make these choices yeah and some of these uh 0:05:42.720,0:05:48.720 manual readings that we have in here when we  think about a manual grow journal things that 0:05:48.720,0:05:53.760 you might already be taking in in a notebook or  any of those type of other documentation ways 0:05:54.320,0:05:59.600 you can now get those directly into our system  and for some of these it's nice to have just as 0:05:59.600,0:06:04.560 a transition period so maybe you are taking uh you  know spot water contents right now or some spot 0:06:05.200,0:06:09.840 ec measurements in that substrate with uh  with various different types maybe you're 0:06:09.840,0:06:14.320 using the solus maybe you're using like you  know some blue lab equipment for these type of 0:06:15.440,0:06:19.520 measurements and what you can do is you can  start to kind of calibrate and get used to 0:06:19.520,0:06:24.640 using time series data from systems like  AROYA where they're automatically taking 0:06:24.640,0:06:29.440 this information and maybe you're just not used  to that so it's a great transition period to start 0:06:29.440,0:06:34.880 just documenting in compare against what you're  seeing in your charts and and kind of get used to 0:06:34.880,0:06:38.480 having a little bit more more free time from  labor and not taking some of those readings 0:06:39.680,0:06:43.600 yeah and you know just honestly getting and  getting to develop those good habits because 0:06:43.600,0:06:47.920 although AROYA is going to capture all kinds of  data for you you've still got to put in enough 0:06:47.920,0:06:53.120 work to organize it you've still got to analyze it  yourself to an extent you know roy is not going to 0:06:53.120,0:06:57.040 just spit out the choices you need to be making  it's going to give you the information that you 0:06:57.040,0:07:01.760 need to make those choices so giving yourself  some context in terms of you know even some 0:07:01.760,0:07:06.640 of these that a lot of us aren't really used to  taking like stem diameter i have never taken that 0:07:06.640,0:07:12.880 on a super regular basis but if i was running  a new nutrient line or trying let's say just 0:07:12.880,0:07:17.040 starting to implement generative growth  strategies and stuff i might want to keep 0:07:17.040,0:07:20.720 track of that because some of my plants are  going to respond by having a much beefier stem 0:07:21.520,0:07:25.760 and hopefully you know having a lot stronger  structure if i don't see that on certain screens 0:07:26.320,0:07:30.480 i i want to know and i want to have it recorded  so that i just have that bit of information about 0:07:30.480,0:07:36.400 that screen and i know what to expect when i  apply certain techniques to it one of the things 0:07:36.400,0:07:41.040 you'll notice in this system is we're letting you  attribute it specifically to a zone so if you are 0:07:41.040,0:07:46.080 using your harsh groups and you've defined what  strains are in what zones really helps you keep 0:07:46.080,0:07:51.760 track of how those strains are behaving and if  you are obviously mono cropping in a room then 0:07:52.480,0:07:56.240 take some uh readings you know  multiple readings across each zone and 0:07:56.240,0:07:59.840 that'll kind of help you understand your  consistencies and then maybe if there's any 0:08:00.800,0:08:07.200 zonality issues within that room as  well so my recommendation is always 0:08:07.200,0:08:13.040 take at least two or three at the very minimum  of those manual readings per zone ideally more 0:08:13.040,0:08:18.160 but you know every manual reading does cost time  so if you can make good decisions based off of 0:08:18.160,0:08:23.200 you know a limited set of of data then  then spend your time doing other things but 0:08:23.200,0:08:27.680 you want to capture more than one so when we look  at things like plant height i always like to try 0:08:27.680,0:08:32.800 and attribute the manual reading to the same  plant that we have some taros 12s installed to 0:08:32.800,0:08:38.240 and then we can correlate that directly to the  data right so maybe i've got a zone with three 0:08:38.240,0:08:44.320 substrate sensors in there i'll take three uh  plant heights and you know depending on how much 0:08:44.320,0:08:49.520 different those are and if those plants accurately  represented the crop then i might take more 0:08:51.840,0:08:55.360 absolutely you know going back  to crop registration is just 0:08:55.360,0:08:58.800 really really really important can't  stress that enough and then you know 0:08:59.440,0:09:03.280 really just not only adding these manual readings  but don't be afraid to add a note in there 0:09:04.000,0:09:08.960 you know take pictures with your notes and then as  you get deeper and deeper you might find yourself 0:09:08.960,0:09:13.600 looking at things like to model conductance here  with you know most people probably don't have a 0:09:13.600,0:09:19.360 leaf parameter but this is you know another really  fun value to look at and say okay are my plants 0:09:19.360,0:09:23.200 doing what i think they're doing we're going to  put that in are they conducting as much water 0:09:23.200,0:09:28.880 through their stomata yes or no water activity  that's you know more of a post-production thing 0:09:29.760,0:09:33.520 but very important we want to establish  that line between when our product is 0:09:34.640,0:09:39.360 too wet and mold can grow or other  bacteria or other pathogens rather 0:09:39.360,0:09:43.760 or it's so dry that you know we've sacrificed  quality and weight it helps with that consistency 0:09:44.720,0:09:50.320 um you know we can go through most of these are  on here they're in here for a reason you know 0:09:50.320,0:09:55.600 you as a grower do you need to take every one of  these maybe not but there are more tools in your 0:09:55.600,0:10:00.800 toolbox to compare how your facility is performing  versus how you expect it to perform and then also 0:10:00.800,0:10:07.840 diversify you know like uh we as a sensing  company don't typically do a lot of controls 0:10:07.840,0:10:12.480 however most facilities we work at have some  sort of automated control system a lot of those 0:10:12.480,0:10:17.680 systems come with a less sophisticated sensor  or a different brand of sensor having that 0:10:17.680,0:10:23.280 redundancy in your system is great so if you want  to say okay i'm going to spot check rh out here 0:10:23.840,0:10:30.480 with uh my brand x environmental controller sensor  that i'm going to check on that platform for now 0:10:30.480,0:10:33.760 i can get that in there once a day let's say you  know it's on the screen that i got to walk up to 0:10:33.760,0:10:38.160 in the room or in the hallway and get i can start  comparing those so i know that when AROYA says 0:10:38.880,0:10:46.240 that we're at 62 humidity and brand x says  we're at 65. okay i personally trust the 0:10:46.240,0:10:52.160 aurora ones more myself but uh now i have a  feeling you know and i i've written it down 0:10:52.160,0:10:56.240 that way when i could go back and say all right  i was yep that's what it was that time not so 0:10:56.240,0:11:00.560 much well i had this feeling that that sensor  was running low or high this week or that week 0:11:01.440,0:11:05.440 you know we want everything to be as repeatable  as possible inside of you know an eight or nine 0:11:05.440,0:11:11.600 week flower period and also any a full plant life  cycle and this you know capturing as much data 0:11:11.600,0:11:16.560 as possible is how we're going to accomplish  that we can look at some of the other control 0:11:16.560,0:11:23.360 systems a lot of times have the ability to run an  offset from their sensor data and what i prefer 0:11:23.360,0:11:28.720 is obviously having your climate stations in a  representative area in the room that's typically 0:11:28.720,0:11:34.160 within a foot of the canopy and you know at  least somewhere in one of the the quadrants or 0:11:34.160,0:11:40.640 towards the middle of the room and if you are  using a controller offset and it's got a different 0:11:40.640,0:11:46.400 climate station than ours get those sensors within  a pretty close range of each other i like to say 0:11:46.400,0:11:51.440 you know if you can have those hanging within a  foot of each other then you're eliminating other 0:11:51.440,0:11:56.240 variables that could account for that offset and  you're you're getting a better capture of the true 0:11:56.240,0:12:00.800 environmental parameters in there oh yeah and  you know i mean another thing too is when you're 0:12:00.800,0:12:04.720 looking at that room and you do have sensor  placement if you're getting some value that 0:12:04.720,0:12:09.280 you don't expect go investigate it and sometimes  you might find that that side of the room i mean 0:12:09.280,0:12:13.120 i've talked to several clients who hang it up  and i can't believe it's that dry in the room 0:12:13.120,0:12:16.800 like why well it's molding show me a picture of  your climate station it's right in front of a fan 0:12:17.440,0:12:21.440 or the d-hue and it's like it's not that as bad on  their part or anything it's just kind of like okay 0:12:21.440,0:12:24.640 anytime we see something like that  we should investigate and then also 0:12:25.440,0:12:31.520 make a record of it so now you've got a spot check  on that device and go okay here's a note when 0:12:31.520,0:12:37.520 i put it by the d u it does not read accurately  it's off by 10 degrees fahrenheit and 20 humidity 0:12:37.520,0:12:44.240 or something like that and i like to kind of think  about these parameters in my head on two different 0:12:45.120,0:12:50.480 uh two different aspects well the first  would be thinking about uniformity so we 0:12:50.480,0:12:56.560 can obviously have crop uniformity and we can  have environmental uniformity and uniformity 0:12:56.560,0:13:01.040 is just an instant snapshot it's a snapshot  of what's going on right at this minute across 0:13:01.040,0:13:08.640 our population across the volume of that room and  obviously if you have good uniformity then you can 0:13:08.640,0:13:13.600 start looking at consistency and i like to think  about consistency as the performance over time 0:13:13.600,0:13:21.520 is the hvac equipment operating as expected you  know every day all the time are our plants growing 0:13:21.520,0:13:27.360 as we expect and so if you can think about  those two as a separate aspect a lot of times 0:13:27.360,0:13:33.120 it's going to help you improve uniformity and  or then look at the specific variables that are 0:13:33.840,0:13:36.240 increasing or decreasing  the consistency over the run 0:13:38.640,0:13:42.640 yeah you've got to separate your variables and  start learning what you can and can't play with 0:13:42.640,0:13:48.000 and what is actually affecting everything and a  lot of times it's really tempting to go oh well 0:13:49.120,0:13:53.040 my yield was terrible on that one i  had high humidity i had low light i had 0:13:53.040,0:13:58.080 this or that you got to pull those apart one at a  time before you can really make a judgment and say 0:13:58.080,0:14:04.000 this is what was wrong like fix everything you  can and then remember that you know in the last 0:14:04.640,0:14:08.160 well a couple hundred years that people  have been doing a lot of plant research 0:14:08.160,0:14:12.880 and trying to really figure out how plants  work you know it used to take a whole summer 0:14:12.880,0:14:17.680 it used to take a whole growing season if  we want to get into fruit breeding or just 0:14:17.680,0:14:22.080 raising fruit trees we're talking about years  to experience any return so that's something 0:14:22.800,0:14:27.440 it's hard to as a grower be patient when  you've got this data right at your fingertips 0:14:28.080,0:14:31.840 you want to act on every little bit of it but  sometimes it's better to keep your consistency 0:14:32.400,0:14:36.560 look at the entire run and then start to make  our decisions for the next run especially if 0:14:36.560,0:14:42.240 there's nothing catastrophic happening you know  if our goal is just to get from 2.5 to 3.5 pounds 0:14:43.440,0:14:46.080 if we've been consistent at  2.5 we're going to do that 0:14:46.800,0:14:50.960 step it up slowly treat it one variable at  a time so that we can observe what happens 0:14:50.960,0:14:56.400 when we just change that one variable yeah  a couple things that you can kick my mind 0:14:56.400,0:15:02.880 there about so an example of analyzing uniformity  using manual readings would be you know taking 0:15:03.440,0:15:09.600 multiple plant heights or multiple runoff ecs  runoff ph's across that room so that's you know 0:15:09.600,0:15:15.280 a snapshot of right now we're saying all right we  have 12 plant height readings from this room what 0:15:15.280,0:15:20.320 is the standard deviation or what's the variation  between our top values and our bottom values 0:15:20.320,0:15:25.920 and then an example of how to use those for  consistency would be taking those readings 0:15:25.920,0:15:33.280 every other day or what your labor allows to to  be most helpful for how your facility operates 0:15:33.280,0:15:38.160 and one of the things that's really cool about  taking notes and adding pictures in here as well 0:15:38.160,0:15:44.160 is you can notify other members on your team so  maybe you did see a big variation in plant height 0:15:44.160,0:15:49.760 across there and you might hit up your your clone  manager tag them in the comments with a pound sign 0:15:49.760,0:15:57.120 and or at sign excuse me and their name and  that'll notify them that uh you know hey 0:15:57.120,0:16:02.320 seth is you know there's something that your clone  team can do to help us improve our uniformity and 0:16:02.320,0:16:07.120 have more projectibility on our crop height  absolutely especially when we start talking about 0:16:07.120,0:16:12.000 some bigger facilities you know as this whole  industry has evolved i've definitely noticed um 0:16:12.720,0:16:16.960 a lot more specialization than we see necessarily  in some other horticultural industries so 0:16:17.760,0:16:22.960 you know it's very typical to have someone  that's just in charge of veg and cloning okay 0:16:22.960,0:16:27.680 well getting this information back to them because  they may not always they're not spending as much 0:16:27.680,0:16:32.880 time in the flower room seeing how those plants  end up nor are they probably doing nearly as much 0:16:32.880,0:16:37.600 between when it leaves their care and the time  they would go look at it so it's really important 0:16:37.600,0:16:42.320 that everyone that's actually you know the art the  human side of it that needs to be appealed to as 0:16:42.320,0:16:49.600 well and everyone's got to have that information  you know if you've got a veg manager that's 0:16:49.600,0:16:54.240 working on cloning they've got a way they like to  do it and it doesn't work they probably have some 0:16:54.240,0:17:00.240 good reasons for doing it the way they do it so  it's it's more of a conversation than just oh hey 0:17:00.240,0:17:06.880 smaller clones oh hey bigger clowns uh like okay  here's here's why you know here's what we're 0:17:06.880,0:17:10.640 looking at guys we gotta adjust a whole host  of different strategies to accomplish this and 0:17:11.600,0:17:14.320 the more data we can have the more  comfortable everyone's gonna be 0:17:15.760,0:17:21.600 one of the major goals of heroic is getting  everyone to work as a team at the facility and 0:17:21.600,0:17:26.560 so we you know we always encourage that you build  out the role permissions and you try and get as 0:17:26.560,0:17:32.240 many people involved documenting into the system  as possible and this really helps the people that 0:17:32.240,0:17:38.160 are good and specialized in a specific area get  get assistance so you know maybe you're doing 0:17:38.160,0:17:44.160 a good job documenting uh your pest management  stuff in here and you you know take a picture of 0:17:44.160,0:17:51.200 your sticky cards and you say hey you know at pm  manager i'm seeing a new type of bug or i'm seeing 0:17:51.200,0:17:56.320 a higher pest load in this room take some pictures  of it tag them in there and it's really just going 0:17:56.320,0:18:01.040 to help them use their time more efficiently  and have have more rise what's going on in 0:18:01.040,0:18:05.600 the room absolutely and that's one thing you  know since we were screen sharing this week i 0:18:05.600,0:18:10.080 might as well show while we're on it you can  really customize each role in the facility 0:18:10.880,0:18:17.280 so you can have everything up to an administrator  you know head honcho down to uh hey we finally hit 0:18:17.280,0:18:20.640 the point in cannabis where you might have some  interns running around doing some of these spot 0:18:20.640,0:18:24.960 readings for you and you can give them the ability  to look at the map and enter readings and that's 0:18:24.960,0:18:31.120 about it if you want so we can really customize  this so everyone in the facility can start using 0:18:31.120,0:18:36.240 it and uh helping build that data set that we're  looking for because there are a lot of moving 0:18:36.240,0:18:42.080 parts if not everyone's on board you're missing  missing little snippets here and there we've tried 0:18:42.080,0:18:47.680 to include as much flexibility on this as possible  because so many of these facilities operate with 0:18:47.680,0:18:53.280 different levels of employees and so you can add  more roles you know if you need 10 rolls in there 0:18:53.280,0:18:59.760 then you can absolutely specify exactly what each  person can access see modify and contribute to 0:19:02.160,0:19:07.600 amazing thank you guys so much for that overview  i actually learned a ton in that but what really 0:19:07.600,0:19:14.320 stands out to me is first of all the importance  of the human element still always but also second 0:19:14.320,0:19:19.760 of all data is just really expanding the gross  toolbox giving you much more insight into stuff 0:19:19.760,0:19:23.920 that you can't see and uh giving you other  considerations maybe that you hadn't thought 0:19:23.920,0:19:32.480 about so um really appreciating that synergy thank  you guys okay well eric is on with us today and he 0:19:32.480,0:19:38.480 posted a question eric you want to go ahead and  mute yourself and ask yeah of course um first of 0:19:38.480,0:19:44.400 all guys i always want to thank you guys for the  last like few weeks i've been on um i'm definitely 0:19:44.400,0:19:49.600 seeing improvements all throughout my run yeah  whether it's my veg or my flower cycle right now 0:19:49.600,0:19:55.600 so appreciate it a lot um had a quick question uh  this shouldn't be too complicated but how large 0:19:55.600,0:20:01.280 do you guys like to keep your p1s relative to your  p2s so i feel like i have an understanding of how 0:20:01.280,0:20:06.640 many shots to bring it up and you know how long  to do it but i'm not understanding what size they 0:20:06.640,0:20:11.840 should be because usually there's a recommended  oh let's say like one to three percent or for veg 0:20:11.840,0:20:17.840 but is that one to three percent the size of the  maintenance shots or the size of the ramp up shots 0:20:17.840,0:20:24.640 and how should you think about that and would  you change that throughout your vegetative or 0:20:24.640,0:20:30.800 um generative steering or it's just like a  set amount for ramp up so i think i'm just 0:20:30.800,0:20:34.560 going to start off with the basics here i don't  necessarily like to think about shot size relative 0:20:34.560,0:20:39.600 to each other uh for generative for example a  lot of times i won't even run any p2 shots we'll 0:20:39.600,0:20:45.280 just be running p1 shots i like to think about  those shot sizes in reference to the substrate 0:20:45.280,0:20:52.480 size and how big our drybacks were so for kind of  just a very general outline of running p1s i like 0:20:52.480,0:21:01.360 to have four shots in one hour and so if i see  about a 20 dryback then i'll need four shots of 0:21:01.360,0:21:08.080 approximately five maybe six percent if i want to  get right up to my field capacity within that hour 0:21:10.160,0:21:13.520 yeah you know i mean it does change it  can change a little bit so when we're 0:21:13.520,0:21:17.280 talking about generative we want to go  minimum shots so if we can hit that in 0:21:17.280,0:21:22.480 four inside one hour and get a 23 hour drive  back that's a great great generative strategy 0:21:24.240,0:21:27.600 when we switch over to veg what we're  looking at is more and more irrigation 0:21:27.600,0:21:32.240 events in the day to push that plant  to grow more that being said if we 0:21:33.920,0:21:38.240 lengthen that out a little bit maybe to two  hours we can fit a lot more one to three percent 0:21:38.240,0:21:43.840 irrigations in and get more events in and push  that that plant more vegetatively in the daytime 0:21:44.480,0:21:51.760 however pushing a plant harder that way is not  necessarily always what we want to do so it's 0:21:51.760,0:21:56.400 really important to go back to taking some of  those manual readings and notes and pictures i 0:21:56.400,0:22:00.720 think pictures speak a thousand words and we're  talking about plants i mean they always do but 0:22:00.720,0:22:06.240 especially to the grower we're used to staring at  plants so uh if you can start to relate some of 0:22:06.240,0:22:09.840 those things in the future it's gonna help  you a lot a couple things to keep in mind 0:22:09.840,0:22:16.160 as well is every once in a while you just have  equipment limitations that don't let you perform 0:22:16.160,0:22:22.000 perfectly as your intentions for crop steering  so thinking about the drip rate of your emitters 0:22:22.640,0:22:27.840 if you've got high flow emitters that are you know  are dripping faster than you'd like you may need 0:22:27.840,0:22:34.320 to split that into shorter durations of irrigation  just to allow the substrate capillary effect to 0:22:34.320,0:22:41.280 help unif or get uniform water content throughout  the entire media and then another thing to kind 0:22:41.280,0:22:46.320 of keep in mind is how much runoff that you're  trying to push for to modulate your ec levels 0:22:46.320,0:22:50.640 and so if if you need a little bit more  runoff sometimes you'll want slightly larger 0:22:50.640,0:22:56.800 shot sizes so that you can pull that ec down yeah  and that's something we're always working with is 0:22:56.800,0:23:01.600 the limitation of the medium that we're working in  you know and rock wool if we put on too big of a 0:23:01.600,0:23:06.720 shot too fast we're gonna get channeling coco same  thing it's gonna run off before we actually hit 0:23:06.720,0:23:11.360 field capacity because as jason said it doesn't  have time to move through the medium with the 0:23:11.360,0:23:16.080 capillary effect so sometimes you know like in  an ideal world if we want to go for a bigger 0:23:16.080,0:23:21.680 and bigger shot with fewer for generative we will  inevitably hit a point with coco it's uh you know 0:23:21.680,0:23:26.640 it can be higher up closer to ten percent maybe  a little more with rockwool six percent seven 0:23:26.640,0:23:32.000 percent is generally pushing on as big of a shot  as we want to put on you know and if we're trying 0:23:32.000,0:23:37.520 to push these push these plants as generatively  as possible we would have and i mean you can see 0:23:37.520,0:23:42.960 this in some very old school growing text you  have a big media size big pot we hit that thing 0:23:42.960,0:23:46.880 once in the morning if the pot is big enough and  the plants small enough we might wait a whole day 0:23:46.880,0:23:52.560 you know two days before we water what we're doing  is giving it one irrigation pulse and then a lot 0:23:52.560,0:23:58.000 of generative stress but at the same time growing  that way we end up with a plant that might be 0:23:58.640,0:24:03.840 four maybe five feet tall out of a five to seven  gallon pot and just not have the weight that we're 0:24:03.840,0:24:08.720 looking for it might have the quality but we  never we never got to that bulking phase the 0:24:08.720,0:24:13.120 plant really couldn't go into overdrive and  that's what we're kind of trying to do is uh 0:24:14.640,0:24:18.160 really time when we want to shift gears with  the plant i guess is a good way to put it 0:24:18.880,0:24:26.800 yeah substrate size one of those things that it's  pretty easy to dial in uh in comparison to some of 0:24:26.800,0:24:31.120 the other challenges that people face and when  it you know if you're a soil grower you're used 0:24:31.120,0:24:37.280 to having larger substrates that you can store  some of the the nutrients in that that living 0:24:37.280,0:24:43.760 soil the thing about hydroponic medias is all  our nutrients are coming from our fertigation 0:24:43.760,0:24:48.640 anyways so as long as we're not causing a  volumetric issue with the roots we can be in 0:24:48.640,0:24:54.560 a little bit smaller substrate and and be able to  keep that plant healthy on the other side of that 0:24:54.560,0:24:58.640 is obviously if our substrate's a little too small  we're going to run into challenges keeping the 0:24:58.640,0:25:03.520 water content high enough when we're doing a long  maybe a 23 hour drive back during our generative 0:25:05.120,0:25:11.200 yeah you know if you're finding that uh you  you can't ripen after bulking just because 0:25:11.200,0:25:16.800 the plant dries out too fast get a bigger pot  quit beating yourself up beating yourself up 0:25:16.800,0:25:23.680 everywhere else and solve the problem in a simple  way or cut your plant size in half but um yeah 0:25:26.240,0:25:30.800 eric did that answer your question uh  absolutely more than enough thank you 0:25:30.800,0:25:34.480 amazing awesome thank you so much for asking  and just a reminder to everybody's on with us 0:25:34.480,0:25:38.480 we're here for you please feel free to type any  questions you have in the chat and actually if 0:25:38.480,0:25:43.120 you want to be entered to win a limited edition  to royal t-shirt type in your email address too 0:25:43.760,0:25:50.400 all right you guys we got quite a few write-ins  this week um this one came from pat who emailed us 0:25:50.400,0:25:56.400 hi folks i have a question regarding ec versus  moisture level starting with the thought of dry 0:25:56.400,0:26:01.680 out causes ec to rise i have a blue lab pulse  and when checking in the morning the moisture 0:26:01.680,0:26:08.960 level may be 25 and the ec 1500 as the irrigation  cycle starts the moisture content starts to rise 0:26:08.960,0:26:14.880 and the ec seems to rise also then the ec  starts to fall as the moisture continues to 0:26:14.880,0:26:19.840 rise is the ryzen ec due to needing more  water for the sensor to read properly 0:26:20.880,0:26:28.320 did you get all that yeah i don't know the  specifics on on what this um blue lab pulse 0:26:28.320,0:26:34.160 meter is using my guess is this is actually just a  physical parameters of the pot and or the pot size 0:26:34.160,0:26:39.280 as that water content is moving through  it during an irrigation you know honestly 0:26:39.280,0:26:43.360 when i look at that right off the bat is if  you're saying 1500 we're talking about ppm 0:26:44.000,0:26:49.600 uh if we convert that with the standard ppm  500 scale over we're looking at about a 3.0 ec 0:26:50.560,0:26:56.320 if you are pushing enough runoff um basically  your plants eating through some of that ec in the 0:26:56.320,0:27:02.640 daytime it's dipping below 3.0 when you go ahead  or 1500 in your case when you go ahead and water 0:27:02.640,0:27:08.880 with a 3.0 ec it's going to come up a little bit  just because that nutrient solution has more salt 0:27:08.880,0:27:13.920 than your than your media does but it's going  to go back down a little bit and then as the 0:27:13.920,0:27:20.640 media dries out we do expect to see that you see  value go up unless it's already a fairly low value 0:27:21.360,0:27:26.640 if we're at a fairly low value which 1500 would  not be very high 3.0 it would not be surprising 0:27:26.640,0:27:32.400 to see that go from 1 500 down to 1 000 back  up to 1500 throughout the day if you had 24 7 0:27:32.400,0:27:36.960 data logging yeah ec is a concentration so  if we have the same amount of nutrients and 0:27:37.520,0:27:43.520 less water then our ec is going to be higher  and the truth is for vice versa as well yep 0:27:43.520,0:27:48.960 and it's just like i said that as you get to  the lower range of ec a lot of times we don't 0:27:48.960,0:27:53.440 see the plants behaving quite like we expect  them to behave at a higher ec in the root zone 0:27:58.000,0:28:00.960 excellent thank you so much pat thank  you for writing in your question 0:28:01.760,0:28:07.200 we got a question from hippo they wanted to  know besides doing generative steering is there 0:28:07.200,0:28:15.840 any other way to get the bud to ripen faster  by adjusting the environment ppfe co2 and dc 0:28:16.880,0:28:22.880 there might be a few things you could try to do  but typically when we look at uh ppfd for instance 0:28:22.880,0:28:28.560 light intensity okay we want to use as much of  that light as possible in the timeline we're given 0:28:29.680,0:28:33.760 losing intensity especially if we have a plant  that you know if we're trying to get it to 0:28:33.760,0:28:37.360 finish that means it's still growing right we're  still packing on a little bit of weight we're 0:28:37.360,0:28:42.320 still ripening trichomes we don't really want to  limit any of our crop limiting factors too hard 0:28:43.040,0:28:46.160 so let's say if we a week early  back off on the light intensity 0:28:47.200,0:28:52.000 well we just created a limitation in the amount of  energy we have available to the plants same thing 0:28:52.000,0:28:58.880 with water we say oh we're going to run them dryer  at the top end you're limiting your plants so uh 0:28:58.880,0:29:04.000 you know a lot of it unfortunately will go back  to genetics there's a few things we can do but 0:29:04.560,0:29:09.600 pretty much once you kick a plant into flowering  it has a timeline that it has to live on you know 0:29:09.600,0:29:15.120 in a big way we can see that as a lot of screens  if we run them at 56 days they'll have a certain 0:29:15.120,0:29:24.640 thca percentage versus thc we pull that at 65 you  might see that ratio reversed so kind of the old 0:29:24.640,0:29:28.880 adage without door growers goes if you want it to  be done and you think it's about ready wait a week 0:29:30.800,0:29:34.640 you know we're i'll go back to  it we're just hitting that point 0:29:34.640,0:29:39.040 in genetic development in cannabis where breeders  are starting to pull together things like 0:29:39.760,0:29:43.280 you know how long is the flowering period  we're really nailing down some of these 0:29:43.280,0:29:47.920 traits that before we just we you know  no one had solid crop registration on and 0:29:48.640,0:29:54.080 no one was sharing it so do i want some  of my strains to finish faster yes but 0:29:54.080,0:29:58.560 do i have to accept the limitations that  running that strain presents absolutely 0:30:02.720,0:30:07.120 that's it mother nature will always be in charge  won't she yeah and i do want to stress that there 0:30:07.120,0:30:12.880 are techniques that people will use like drought  stress or you know low temp stress to try to speed 0:30:12.880,0:30:18.640 that up if we do that we are strongly risking  damaging the plant and pulling down a less 0:30:18.640,0:30:24.720 healthy plant which isn't what we want you know  if we're trying to force it to finish or force it 0:30:24.720,0:30:28.080 we are probably compromising some  quality somewhere along the way or 0:30:28.960,0:30:32.880 you know like if we're talking about temperature  stress looking at potentially running into 0:30:32.880,0:30:37.520 mold issues and other facility problems  that we just don't need to have present 0:30:41.280,0:30:45.360 excellent that's great thank you so much eric  you had another question you want to go ahead and 0:30:45.360,0:30:50.960 admit yourself uh yeah um so one  question for you guys i recently 0:30:50.960,0:30:56.480 got some winches installed so my lights are  much easier to adjust i guess up and down so 0:30:57.200,0:31:03.120 you know you get that uh that flexibility  you'd like and i've been pretty close like 0:31:03.120,0:31:07.760 within that one foot of my canopy and  i don't see any signs of light burn 0:31:07.760,0:31:13.280 but have you guys noticed anything like other than  maybe the leaves like my leaves look healthy um 0:31:13.920,0:31:19.840 that would indicate you're pushing too hard and if  you guys have any guidance there so specifics to 0:31:19.840,0:31:27.440 life cannabis is a very light hungry plant it  grows fast it can harvest a ton of energy and 0:31:27.440,0:31:32.080 so you know if you're using something like leds i  don't necessarily get concerned about being within 0:31:32.080,0:31:37.360 a foot of it here's something like hps's you get  a little concerned because the heat from those is 0:31:37.360,0:31:42.240 going to modify your environment your vpd so the  relative humidity temperatures are going to be 0:31:43.120,0:31:47.840 less controlled less ideal than you want  right at the top of the canopy but if your 0:31:47.840,0:31:52.400 light quantities are what you want with that  led and you're not seeing any negative impacts 0:31:53.520,0:31:58.720 i'd keep doing what you're doing yeah in terms  of light typically it'll tell you like in the 0:31:58.720,0:32:05.680 led situation i have run lights too close which  is basically touching them and they turn white 0:32:05.680,0:32:10.400 they bleach pretty hard or you know like with  the hps basically it just gets really hot the 0:32:10.400,0:32:14.240 closer you get to that light so if you're inside  i'm guessing you're at led if it's a foot because 0:32:14.240,0:32:20.160 with hps you probably would have have some of  that clawing dried out bud leaves general torching 0:32:21.200,0:32:27.200 um yeah what do you mean by getting too  white so basically they'll look albino 0:32:27.200,0:32:30.800 if you have them too close to those  leds like they'll just bleach it out 0:32:34.800,0:32:40.320 gotcha all right thank you thanks for your  question eric this is a perfect segue into 0:32:40.320,0:32:44.640 a question we got from ryan at wild west  genetics they're looking for some advice 0:32:45.200,0:32:49.280 we wrote i have an led room that is about to  harvest but the plants don't look as finished 0:32:49.280,0:32:54.000 as they normally do in our hps room some plants  still have light colored hairs when normally 0:32:54.000,0:33:01.760 they look more finished now the canopy is  at 990 to 1050 mole any thoughts yeah so 0:33:02.720,0:33:07.120 we're looking at the spectrum from leds  versus hps that's probably going to be the 0:33:07.760,0:33:13.520 factory that's playing in into this and so a  lot of hps's have quite a bit of red and far red 0:33:14.320,0:33:20.560 typically that's something we'd see in fall and  that's going to encourage those plants to ripen up 0:33:20.560,0:33:27.200 a little bit with leds they're going to be usually  closer into the actual photosynthetic ranges 0:33:27.920,0:33:33.120 for chlorophyll a and chlorophyll b so i  like that sometimes because we can grow 0:33:33.120,0:33:38.400 quite a bit larger plant maybe we'll have to  extend the harvest session by a few days in order 0:33:38.400,0:33:44.000 to achieve the same ripeness typically you know  even on top of the efficiencies that we've added 0:33:45.200,0:33:51.200 for utilities of using leds but a lot of times  you're going to get more weight because they're 0:33:51.200,0:33:55.040 pushing the right wavelength for those plants  to harvest and it is going to be brand dependent 0:33:55.600,0:34:02.160 fortunately leds have come a long ways in the  last five to ten years and manufacturers are 0:34:02.160,0:34:07.680 much more likely to have a well-tailored spectrum  so you know if you have any concerns look up the 0:34:07.680,0:34:14.080 manufacturer the model that you have take a look  at those spectrums and then do a little bit of 0:34:14.080,0:34:19.680 research on how plants behave yeah and you know  something to remember because like that hps we're 0:34:19.680,0:34:24.560 running that far red we don't have the ability to  like slowly bring that in one thing we are doing 0:34:24.560,0:34:28.720 is pushing a little bit of stress on the plant  that way the whole time by having not quite the 0:34:28.720,0:34:34.560 ideal spectrum so one way to look at it is like  yes maybe i do add a week switching to leds on 0:34:34.560,0:34:41.040 this strain however that's an extra week to grow  more mass and i have a more efficient light that's 0:34:41.040,0:34:45.200 allowing me to grow more mass per amount of  energy i'm putting in in the form of light so 0:34:46.800,0:34:50.800 again do we want them all to finish  early of course we do but if we can 0:34:50.800,0:34:54.080 work more with the plant rather than against  it we're always going to get a better result 0:34:54.800,0:35:01.200 and another thing is thinking about the rim  parameters so your environment with leds because 0:35:01.200,0:35:05.280 you've got less radiation hitting those leaf  surfaces a lot of times you're going to need 0:35:05.280,0:35:10.080 to up the temperature in your room uh slightly to  accommodate the change that the plant's feeling 0:35:11.120,0:35:15.760 yeah and that's i mean that's another tool  that's always good for a grower to have is a 0:35:15.760,0:35:21.120 small laser thermometer go get your leaf temp see  like how much radiant energy that light's actually 0:35:21.120,0:35:25.920 putting out you know if you're seeing a leaf temp  that's spiking up in the upper 80s and low 90s 0:35:26.640,0:35:31.200 move your hps up a little bit you know what you  might find though is like with the leds and a 0:35:31.200,0:35:35.360 lot of them just put out i mean some of the newer  models with uv supplementation a little bit of far 0:35:35.360,0:35:40.960 red will help out with that leaf temp but a lot of  growers find that taking that heat source of the 0:35:40.960,0:35:45.440 hps out of the room really does result in having  to significantly pump up the temperature in there 0:35:46.000,0:35:49.680 like the difference being that before  they never had to run their heat ever 0:35:50.240,0:35:54.000 and now they have to for quite a bit of  the year just to get it up to let's say 0:35:54.000,0:36:00.480 82 as a leaf surface tent it's one of the reasons  we love using paper pressure deficit to analyze 0:36:00.480,0:36:05.520 a room when we think about that temperature being  higher with hps as well hps's are also burning off 0:36:05.520,0:36:11.040 relative humidity so make sure that you've checked  in and that your room and those facilities can 0:36:11.600,0:36:16.400 accommodate the change that you've made  from running hps now and running led lights 0:36:19.360,0:36:24.240 dropping the knowledge i love it okay so just  a reminder for everybody who's on with us don't 0:36:24.240,0:36:30.160 forget to type your question in the chat  um this question came in from uh bmg 389 0:36:30.160,0:36:35.360 you guys spoke a little bit earlier about light  intensity so um they wrote some growers lower 0:36:35.360,0:36:43.600 light intensity and co2 later in flower any cons  to this save a little money yeah i mean it just 0:36:43.600,0:36:49.840 depends on how much you're talking about lowering  it obviously uh during the end of the cycle 0:36:49.840,0:36:55.600 the the plan is a little bit less vigorous in the  amount of growth is it's turning its chemicals 0:36:55.600,0:37:01.200 into a ripened product and so you might be able  to get away with it as long as you're not seeing 0:37:01.200,0:37:08.320 a significant decrease in your production yeah i  would you know much much like tapering off your 0:37:08.320,0:37:13.280 nutrient regimen you know do it do it minimally  you don't have to do it too much and uh you know 0:37:13.280,0:37:19.440 typically as far as light intensity goes um  we still are not really approaching indoors 0:37:20.320,0:37:26.400 what direct sunlight is outside so lowering it  back say 20 on your indoor grow light typically 0:37:26.400,0:37:30.880 isn't going to have the same kind of effect as you  as you know putting a shade glo cloth up outside 0:37:32.400,0:37:37.920 so looking at it you know you'd really to say for  sure that you want to do that i would want to have 0:37:37.920,0:37:42.960 some trial data and say all right when i did this  did this in fact increase my terpene content or my 0:37:42.960,0:37:48.640 thc content what what exactly happened because  some of those pathways too we're talking about 0:37:48.640,0:37:55.840 cannabinoid and terpene formation in the plant  have to do with time and energy inputs so if we 0:37:55.840,0:37:59.360 don't have intense enough light at the right  time you know some strains are going to ripen 0:37:59.360,0:38:03.520 earlier but they would actually be ripening  in some pretty warm months like late august 0:38:03.520,0:38:09.120 early september where they're from we may not  necessarily need to have a big overnight diff or 0:38:09.120,0:38:14.480 a big you know softening up at the end to try to  bring them down i think a lot of that knowledge or 0:38:15.200,0:38:19.040 techniques kind of came from the idea that  you know in the fall we get less intense light 0:38:20.640,0:38:24.960 then that's somewhat true but the far  red has a much bigger impact on that 0:38:25.760,0:38:29.440 than say lowering your light intensity  a little bit and as far as co2 goes 0:38:31.040,0:38:36.080 you know if it saves you money cool i  would just never drop my co2 below my ppfd 0:38:39.680,0:38:45.280 excellent thank you guys um so ryan at wild  west genetics had a couple other questions 0:38:45.280,0:38:50.800 specifically about um larging harvest data  in AROYA so they wrote when recording harvest 0:38:50.800,0:38:55.920 data is there a way to specify plants taken for  live extraction they wouldn't have a dry weight 0:38:58.640,0:39:04.160 so if you're using uh our metric integrated  version of the software that actually can 0:39:04.160,0:39:09.040 get captured because you're immediately going to  be putting it in a package however we are still 0:39:09.040,0:39:13.680 coming out with more and more analytic options  over time to give you control on how you want 0:39:13.680,0:39:18.560 to evaluate your harvest because that's a good  point we do have several growers that are going 0:39:18.560,0:39:23.600 straight to only fresh frozen for instance or a  certain portion of their crop is going to fresh 0:39:23.600,0:39:29.520 frozen a certain portion is going straight to  wet flower we're working on having more options 0:39:29.520,0:39:34.640 to evaluate that and one of those in the future  would be hopefully you know a historic poll which 0:39:34.640,0:39:38.800 we're looking at being will access some of your  previous data that's held in compliance databases 0:39:40.240,0:39:45.200 and uh yeah just overall trying to  get more harvest analytics for you 0:39:48.000,0:39:52.960 success their other question was any plans to  link harvest data data with metrics so currently 0:39:52.960,0:39:57.840 you can link harvest data to metric yes if you're  doing it in metric it all pipes right in because 0:39:57.840,0:40:02.560 you're getting the weights directly through arroya  that data actually is generated in roy and then 0:40:02.560,0:40:08.480 pushed up to metrics so that goes right in but  then we have to be clear that this functionality 0:40:08.480,0:40:14.800 does depend on where they're located right correct  yeah so right now market you're in yeah we support 0:40:14.800,0:40:22.320 california colorado michigan massachusetts nevada  i do believe for the the states that we have an 0:40:22.320,0:40:28.000 inactive metric integration for we're working  on uh deploying that in other metric states 0:40:28.000,0:40:33.120 one of the exciting things for uh those people  that we haven't addressed their state yet or are 0:40:33.120,0:40:38.880 not using metric is kept rolling out with  our generic our generic harvest workflow 0:40:38.880,0:40:43.520 and so that's going to just help people  capture those harvest weights using 0:40:43.520,0:40:50.800 the rfid and bluetooth scale that we sell with  the system we call it our touchless harvest system 0:40:50.800,0:40:56.480 it's great because you're not getting trichomes  all over your uh your computer or your cell phone 0:40:56.480,0:41:02.400 or in your notebook and it's also eliminating any  of the chances of error because you swipe your 0:41:02.400,0:41:07.280 your tag you weigh up that plant and it's going to  capture those weights pretty quickly yeah no more 0:41:07.280,0:41:13.440 change in the glove just to try to write it down  and be able to let go of the pen you know i know 0:41:16.640,0:41:21.360 awesome thank you okay so we have our son who's  on with us arson uh you have a question you want 0:41:21.360,0:41:28.000 to unmute yourself and ask away yes hi guys uh  first time viewer again sorry if you went over 0:41:28.000,0:41:34.160 this like a thousand times um i have i have a  room right now and we just harvested this is my 0:41:34.160,0:41:40.560 i want to say third one fourth one so i've had  some success but i feel like every time i cut my 0:41:40.560,0:41:44.880 plants and i hang them and going through the  whole drying and curing process i feel like 0:41:44.880,0:41:50.800 that's where i'm lacking some sort of guidance  or direction because it always seems to go south 0:41:51.680,0:41:57.600 so i don't really touch the humidity all that  much i just keep a fan on for air circulation in 0:41:57.600,0:42:04.480 the room and just maintain a temperature of around  70 degrees more or less um and that normally takes 0:42:04.480,0:42:08.240 about seven to ten days to dry so that's why i  haven't really been messing with the humidity or 0:42:08.240,0:42:14.480 anything at all um and the curing process once  we trim the trim the buds and put them in their 0:42:14.480,0:42:22.000 individual packages i uh put in those humidity  packets to maintain around 62 humidity so i just 0:42:22.000,0:42:25.440 want to know is there anything that i'm doing  wrong is there anything that i'm doing right 0:42:25.440,0:42:31.200 is there anything i can do better just general  guidance would be very helpful when when you say 0:42:31.200,0:42:36.160 that part of the process goes south can you detail  us kind of what uh what goals you're not achieving 0:42:37.680,0:42:44.640 well the the first the very first batch  that i did i was pulling in about 2.2 to 0.3 0:42:44.640,0:42:50.320 uh pounds per light and then after that i have  not been able to even hit that so it's been more 0:42:50.320,0:42:55.440 around like 1.7 uh 1.9 i think was that was the  max that i got and i don't know what's going to 0:42:55.440,0:43:02.160 be the next run this this run but um i'm not  anticipating it being over 2.7 again or 2.2 0:43:02.160,0:43:07.280 again so i just want to be hitting more yield  essentially so i don't know if i'm messing up 0:43:07.280,0:43:13.440 on the whole grow or just the drying process but  um yeah that's the that's the phase i'm in right 0:43:13.440,0:43:21.360 now so i just figured i might ask yeah so this is  where i would uh utilize different checkpoints of 0:43:21.360,0:43:26.240 data analytics so looking at your wet weights you  know the wet weights coming through consistently 0:43:26.240,0:43:31.360 or you know is it you know a decreased  proficiency in the cultivation that's actually 0:43:31.360,0:43:39.360 uh less dry yield uh if those wet weights  are all fairly same we endure increasing your 0:43:39.360,0:43:46.240 decrease then definitely take a look at the drying  process and that means attributing your cultivars 0:43:46.240,0:43:52.480 are you know we're looking at cultivars that maybe  just dry lose more wet weight than others and so 0:43:52.480,0:43:58.080 obviously those variables are going to help you  determine which uh which process to to take a look 0:43:58.080,0:44:05.120 at and how to run that one of the tools that we do  sell is called a water activity meter and it's a 0:44:05.120,0:44:11.520 very common sensor and industrial applications  of uh cereal manufacturing uh jerky process 0:44:11.520,0:44:18.000 control and any of those other food industries  it's actually what we've used the sensor for uh 0:44:18.000,0:44:23.200 quite a bit here in the history of meter group so  we're selling those into the cannabis industries 0:44:23.200,0:44:29.280 that you can go in and document what the the dry  downs or the water activity you know the loss of 0:44:29.280,0:44:36.560 moisture during your dry cycle looks like and help  you really standardize and make sure that your 0:44:36.560,0:44:42.800 your product is going out safe so if we do  have a plant that's got much larger buds we 0:44:42.800,0:44:47.360 may need to keep it in the room a little bit  longer and by documenting that water activity 0:44:47.360,0:44:52.720 you'll know exactly when to be taking it out to  achieve the correct wet weight keep the quality 0:44:52.720,0:44:56.960 of the product up and then also keep that  weight on the bud and make sure that it is 0:44:56.960,0:45:03.040 going to be satisfying your test constraints for  sale yeah if if you haven't been having you know 0:45:03.040,0:45:08.480 any quality problems or big problems with mold  forming in your dry room i would keep doing what 0:45:08.480,0:45:13.360 you're doing for the most part typically i run a  little bit lower temp you know around 60 and 62 0:45:15.360,0:45:21.200 but otherwise if you're not if quality is not your  problem i would definitely be looking more into 0:45:21.200,0:45:26.800 the cultivation side however one thing to always  watch out for you know seven to ten days for some 0:45:26.800,0:45:32.800 strains is a little even on the short side um  having some kind of sensor in the room so we can 0:45:32.800,0:45:36.960 monitor you know humidity in the room while it's  drying down and try to keep things consistent is 0:45:36.960,0:45:40.960 pretty key because we want to get past a certain  point when we first dry down to avoid mold 0:45:41.600,0:45:47.280 then we want to slow that process down if we dry  too fast that cure is just not going to work right 0:45:47.920,0:45:52.400 if that's bone dry in there we can't get the  chemical breakdown we want we can't get that 0:45:52.400,0:45:58.000 quality cure so another thing to kind of think  about uh you know as i mentioned those those 0:45:58.000,0:46:04.080 data choke points if you will is thinking about  the other handling involved with that product so 0:46:04.080,0:46:11.360 if you are carrying it just perfect and it ends  up in a processing room you know maybe during 0:46:11.920,0:46:19.200 breakdown trim rolling whatever your post process  is there are that humidity might be able to be 0:46:19.200,0:46:25.040 increased in those rooms to to help that product  stay at just the right water activity now if that 0:46:25.040,0:46:30.720 water activity goes in it's a .55 on those plants  and then they go into a room that's 30 percent 0:46:30.720,0:46:36.800 humidity they're going to actively lose weight and  they're going to lose some quality to that room 0:46:36.800,0:46:41.840 trying to get to equilibrium with the humidity  in any environment that they're residing in 0:46:42.640,0:46:46.640 absolutely that's a good point bringing  up processing and uh you know especially 0:46:46.640,0:46:51.760 joint rolling a lot of times that is not the  quickest process the product is you know in an 0:46:51.760,0:46:56.000 open environment for a fair amount of time we're  working with something that we grind you know 0:46:56.000,0:46:59.680 there's a few different ways to do that but we're  grinding it up we're exposing more surface area 0:47:00.320,0:47:05.280 so that's that's another point you know we want  to make sure that we're keeping that consistent 0:47:05.280,0:47:11.040 the whole time all the way into packaging  uh yeah we're just losing grams to the air 0:47:13.280,0:47:17.680 and so just you know a good example is  if our product goes into a processing 0:47:17.680,0:47:22.880 room and the product is at 0.55 for  water activity if our room is at 55 0:47:22.880,0:47:27.840 humidity there's going to be no increase or  decrease in the water activity of that product 0:47:32.880,0:47:39.200 arson did that answer your question absolutely  did thank you so much gentlemen awesome thank 0:47:39.200,0:47:43.200 you for joining us and for submitting your  question we we're happy to have you and 0:47:43.200,0:47:47.600 would love to send you an AROYA hat if you're up  for uh dropping your email address in the chat 0:47:49.440,0:47:53.440 yeah for sure i'll do that right now wonderful  excellent and then that's a reminder everybody 0:47:53.440,0:47:57.200 else on with us if you ask a question for  the first time live we will send you a hat 0:47:57.760,0:48:01.760 um all right well we've got a few more  questions just to close out the show just 0:48:01.760,0:48:07.600 kind of some general looks like some crop steering  questions so let's get to this one from space dog 0:48:07.600,0:48:13.760 select they want to know what's more important  substrate conditions or hitting specific drybacks 0:48:15.200,0:48:22.720 i think drybacks are a substrate condition um so  i guess it's gonna be really hard to prioritize 0:48:22.720,0:48:28.560 those because they are interrelated uh you  know obviously if your substrate conditions are 0:48:28.560,0:48:32.880 way off maybe you dried back too much or  you didn't get back up to field capacity 0:48:34.880,0:48:39.120 not sure where to go with this question yeah  so i think there's a few things to talk about 0:48:39.120,0:48:43.440 here like substrate condition in terms of how  well it's maintained the functionality we want 0:48:43.440,0:48:49.840 it to so in terms of rock wool really value your  rockwell's ability to retain water and have a high 0:48:49.840,0:48:55.520 field capacity over pushing a bigger dryback  so let's say we're running 55 field capacity 0:48:56.080,0:49:02.800 or at 55 in our rockwool and we just had a  burning desire to run a 30 dryback because 0:49:02.800,0:49:08.480 we've heard that's cool um yeah losing  your field capacity is not worth it 0:49:09.600,0:49:14.480 basically you know your media is what's  keeping your plant alive so we always have 0:49:14.480,0:49:20.800 to work inside of keeping that media inside of  a good you know a workable range of conditions 0:49:21.520,0:49:27.120 so as jason said they're very interrelated but you  can start looking at with different media types 0:49:27.120,0:49:30.560 where the limits to your dryback might  need to be to maintain those conditions 0:49:31.360,0:49:35.680 so in rockwool you know we're trying to keep it  above 35-40 percent all the time and in cocoa 0:49:35.680,0:49:39.920 usually call about 20 percent the bottom  line just so we don't have a plant that's 0:49:39.920,0:49:44.080 on the other end of the table that's a little  drier than the others hit 12 and actually wilt 0:49:48.720,0:49:54.800 wonderfully guys thank you so much i think this  is a good one for us to close off on here los 0:49:54.800,0:50:01.040 greene goss wrote in why is it important to give  intervals between shots during irrigation and how 0:50:01.040,0:50:07.440 long max should i wait great question uh i think  we hit it a little bit earlier on just talking 0:50:07.440,0:50:13.520 about giving the substrate a chance to to soak  up so that's capillary effect of a substrate 0:50:13.520,0:50:17.280 be slightly different for different  types of medias rockwool for example 0:50:17.280,0:50:24.960 has very good capillary effect just because it's  a unanimous it's very consistent uniform product 0:50:24.960,0:50:29.760 and i think i've used this analogy a couple  times before and it's just a you know dry sponge 0:50:29.760,0:50:36.240 and so if we've got a dry kitchen sponge and we've  got it under a sink that's dripping slightly then 0:50:36.240,0:50:41.040 it's going to help get that entire thing  saturated up as the capillary effect 0:50:41.040,0:50:47.040 pulls moisture throughout the sponge now if  we've got the sink on high it's very likely 0:50:47.040,0:50:51.760 just going to saturate the middle of the sponge  and then start running through the bottom before 0:50:51.760,0:50:56.560 the capillary effect has the ability to catch up  so it's one of the reasons that we like lower flow 0:50:56.560,0:51:03.680 drip emitters and it's one of the reasons that we  do intervals in between shots yep and we also want 0:51:03.680,0:51:09.200 to maintain a healthy root zone so for instance  if we had a dripper running on there let's say 0:51:09.200,0:51:15.200 24 7 constant flow we're really not giving the  chance for the media to drain a little bit and 0:51:15.200,0:51:20.400 pull air down into the root zone we really  need a heavily oxygenated environment so 0:51:20.960,0:51:25.040 if we're you're getting too much and not allowing  a dryback like let's say we're trying to go for a 0:51:25.040,0:51:30.160 point one percent and maintain a straight line  all afternoon we're not giving the planet the 0:51:30.880,0:51:34.960 media a chance to have any you know the right  amount of water and air movement through it 0:51:35.840,0:51:42.400 which is very essential yeah and so it's a  it's a vacuum that i mean is caused so when 0:51:42.400,0:51:47.280 we irrigate that water is going to pull  down through the substrate and behind 0:51:47.280,0:51:54.240 it it's pulling fresh oxygen and basically  rejuvenating those roots uh easy indicator that 0:51:54.240,0:52:00.400 there's not enough oxygen or maybe some other  issue is roots that are a little brownish so 0:52:00.400,0:52:06.720 obviously we're looking for very healthy robust  white roots uh some people do increase the 0:52:06.720,0:52:13.040 dissolved oxygen in their fertigation systems to  also help provide that uh that fresh air the roots 0:52:14.160,0:52:18.320 oh yeah absolutely that's you know that's probably  one of the keys there just watch for those 0:52:18.320,0:52:24.000 traditional over underwatering stress signs if  your block is super wet and your plants wilted 0:52:24.000,0:52:29.120 and it's kind of squishy down by the base you got  brown roots you're probably not really letting it 0:52:29.120,0:52:34.160 get enough of a dry back and really uh  refresh the root zone it's drowning yep 0:52:38.320,0:52:41.840 amazing thank you guys you also have me  uh thinking i gotta take a look at my 0:52:41.840,0:52:46.560 little can of babies in the backyard i am a  notorious over waterer i'm always so worried 0:52:48.560,0:52:55.760 get some pearlite get some pearl okay excellent  i'm on it you guys posted um seth and jason thank 0:52:55.760,0:53:00.560 you so much for what an excellent
