[00:00:00] Kaisha: Hello, how's it growing? Friends, welcome to Office Hours, your source for free cannabis cultivation education. My name is Kaisha, and today I am moderating solo, but she know we do, we're going live on YouTube. So if you're logging in over there, make sure you send us your questions. You're active on social media.

[00:00:17] Kaisha: Be sure you're following us on all the platforms. We are on Instagram, TikTok, YouTube, LinkedIn, and Social Club. If you're live with us here and have a question type at any time in the chat. And if your question gets picked, we'll either have you unmute yourself or I can ask. For [00:00:30] you, Jason. It's just me and you today.

[00:00:32] Kaisha: How are you? Yeah, it's quiet. Quiet

[00:00:35] Jason: show. Quiet house. I'm doing pretty well. Awesome.

[00:00:38] Kaisha: Good to see you. All right, well, let's get through it. We already have some questions that we received. Dave Ray wrote in if we have plants that are smaller than we would like in early flower, would it make sense to start steering vegetatively before the typical day 21?

[00:00:55] Jason: Possibly, I mean, obviously the ideal situation here would be to. [00:01:00] Veg for just a little bit longer. And when we're talking about crop registration, for me, you know, that's one of the biggest factors in making sure that I have a predictable reproducible crop. And that is looking at plant height when we're coming out of edge.

[00:01:13] Jason: And so, Ideally, you know, taking a plant height, coming out of edge, we're hitting that day. Every time that we do veg, a specific genetic and then keeping track of plant heights throughout that generative sharing. Most of the time if we do go back to some vegetative, [00:01:30] bulking a little bit early in flower, we're gonna see some of that buds structure stretching out a tad bit worked with.

[00:01:37] Jason: A number of people where, you know, they'll see like two, three inches of growth in the first couple days of going back to veg bulking. And that's an easy indicator that hey, we still need to be putting some g generative steering to that plant to make sure that we're getting the best bud quality possible.

[00:01:57] Kaisha: Awesome. Yeah. Thank you for that. Jason. I actually, I am gonna [00:02:00] drop in the chat here. We have a really great blog post on the data you should be keeping track of when you're doing registration, so that's a good one to reference as you go forward. Dave, Ray, good luck. Keep us posted on what's going on. All right, I'm gonna keep it moving to our submitted questions, and if you have a question.

[00:02:16] Kaisha: Be sure to drop it in the chat so we can get Jason's insights. Diane submitted this question last week. We didn't have time to get into it, but he wrote in, Seth was talking about plant metabolism. He says 82 Fahrenheit leaf [00:02:30] temperature, or 82 Fahrenheit room temperature is the optimum metabolism.

[00:02:34] Kaisha: What's gonna happen if we go above those numbers? Any insights into that?

[00:02:40] Jason: Yeah, a absolutely. And so, you know, when we're talking about some of the ideal metabolisms, leaf temperature is gonna be the most important number there. And that's just gonna help you target what your room temp should be. For rooms that we have a little bit less far red light.

[00:02:56] Jason: So if we're running under maybe C M H or [00:03:00] especially with LEDs, we're gonna run the room temps a little bit higher than we would typically with an h Ps setup. And so we're shooting for that, you know, probably about 82 range for leaf temperature. Obviously there can be some slight genetic variation in what is gonna help that plant metabolize the fastest.

[00:03:16] Jason: If we go up. Too much higher. That plant's actually gonna start metabolizing a little bit slower as it's using more energy, using more water to try and cool itself. So those stone mates are gonna start to close up a little bit to try and retain water, [00:03:30] and it's gonna push water through the plant faster in order to transpire as much as possible, even though those stone mates are starting to close up.

[00:03:39] Kaisha: Awesome. Thank you so much for that. Diane. Thank you for that question. We usually see you on the show, so if you have any other follow ups, be sure to post those. All right. Caesar submitted this question, and I think we kind of talked about it a few episodes ago, but let's get another overview here.

[00:03:53] Kaisha: He wrote in, do non-top plants yield more than top plants?[00:04:00]

[00:04:00] Jason: Typically you're gonna get a little bit more yield if everything else is the same as far as how long we're growing these you know, same nutrients, same de leafing practices. A lot of times a top plant is gonna give you just a little bit less, right? So this plant is building biomass throughout its entire life cycle and Really what happens if we are topping is we're just getting rid of some of that bio mask.

[00:04:21] Jason: It's gonna sometimes slow down some of the growth to that plant. Obviously topping does have its place. It depends on what's your facility configurations. [00:04:30] If we have, you know, limited light at the canopy, we wanna get as much bud exposed to that as possible. So we might do some training. And some topping to try and make sure that that we're getting as much light exposure to the top of those plants as well.

[00:04:43] Jason: You know, same thing with limited height. If we've got like a two-tier or a three-tier flowering room or we just have a really short flower room, we might need to do a little bit of height restriction in order to get the best. Production outta that plant. You know, that being said a lot of people are [00:05:00] successful with pinching to try and do the same type of response in the plant or instead of having a apical maritim We're gonna have a few branches that are competing for that top light.

[00:05:11] Jason: You know, hi historically with unlimited facility constraints and really good genetics. Most of the time, you know, if we're growing a five foot tall plant, we're gonna see a little bit more bud production, a little bit more total mass than we will if we're you know, damaging that plant and or removing some biomass from it.

[00:05:29] Jason: So,[00:05:30] and my preference usually is to try and have as best of cloning and consistency up to the point. And then you may not need to do topping to even out the canopy quite as much.

[00:05:42] Kaisha: Yeah, that's a good tip. Okay. Excellent. Well we got a question in from Iron Armor on YouTube. They wrote in doing a small pheno hunt and wondering how to keep the seedlings from stretching so much.

[00:05:55] Kaisha: Roughly how much P F D can a new seedling take, and what is the minimum veg [00:06:00] time before I can switch a seed to flowering? What advice do you have for iron armor?

[00:06:05] Jason: Oh yeah. So, you know, maximum amount of P F D for a seedling, I, you know, it's gonna rapidly increase. It's almost on a daily basis as that thing is becoming more mature.

[00:06:18] Jason: You know, when we're germinating those seats can germinate in pure darkness. You know, maybe for the first few days we wanna be at like one or 200 micromoles. You know, typically by the time that we [00:06:30] are a week or two in, we'll wanna be up in that 300 plus micromoles range so that we're making sure that we're keeping those plants, like you said, keep 'em from stretching.

[00:06:39] Jason: You know, a lot of times plants that are not. Getting enough light for the stage in the life cycle, they'll start to elongate. What they're trying to do is get closer to the light. They're trying to capture as much energy as possible, so, and is really genetic dependent as well. You know, we see some strains that will mature much quicker in the early stage.

[00:06:58] Jason: And then we see some [00:07:00] strains that don't mature as quick and they catch up. You know, late veg, early flower timeline. So, I wish I had exact numbers and times to, you know, to put out there. But it just really comes down to what what are we working with? And, you know, it also comes down to what your light types are.

[00:07:17] Jason: You know, I mentioned here a little bit earlier, the increased solar radiation, or excuse me, just radiation from. Far red and what that's doing is increasing our leaf temps. And as these plants are smaller, they have [00:07:30] even less capability of regulating their leaf temps, obviously. Less total stone mates because there's less surface area.

[00:07:36] Jason: And so the little bit tighter controls do help those plants stabilize themselves. You know, so that being said, with something like an L e D. You might be able to actually push a little bit more P F D you know, especially if it's a l e D that doesn't necessarily have a lot of of the higher end wavelengths.

[00:07:53] Jason: Okay, so your fluorescence that's a great way to start as well because they're nice and even, you know, it's really nice, consistent soft [00:08:00] light. You know, that being said, you know, We're getting the most light to those plants early on. Fluorescence. You're just gonna run out of P F D fairly quickly and have to transition to a more powerful light type.

[00:08:15] Kaisha: All right. Awesome. Thank you a armer for your question and you know, if you have any follow ups, let us know. We are live with Jason. If you have any questions for the experts, be sure to drop those in the chat on YouTube and here on Hangouts. We got something new here from M five B W [00:08:30] they wrote in. Do you have a template schedule for working with five G P H in meters to four for six by six rockwool?

[00:08:41] Kaisha: On vegetative and generative feeding. For example, if my lights turn on at eight, my first feeding would be at 10. And for how many minutes then when would be the next one be for P one and for P two? Did I say that in a way that makes sense, Jason? Yeah. So,

[00:08:59] Jason: Half [00:09:00] gallon emitters what did I say?

[00:09:01] Jason: What is here? Six by six by four pots. It's not really gonna matter as much. You know, you'll just adjust how long you are for the size of substrate. My baseline recommendations when we are running generative you know, point pilot gallons in a nice, fairly slow ammeter. You know, my favorites are a little bit lower than that.

[00:09:20] Jason: Anytime that we're getting into the one or two gallon per hour meta we definitely need to increase the the number of shots so that we can try and help the [00:09:30] substrate stay saturated, like the capillary effect, trying to avoid runoff. Or nutrient channeling basically. And so, you know, instead of like for 0.5 s I would do, you know, if, so if your lights are coming on at 8:00 AM I would probably irrigate my first shot at 9:00 AM then I'd do 9 15, 9 30, 9 45.

[00:09:51] Jason: Tell 'em up till to saturation. So per a fairly A fairly aggressive generative irrigation, trying to get up to field [00:10:00] capacity within an hour of that first irrigation. And usually we're starting that first irrigation one to two hours after lights on. And so in kinda getting back to the point, if you heard a higher drip rate, like a two gallon per hour, I'd be like, Hey, let's try and get, you know, Eight irrigations in to get up to field capacity just to try and reduce how much water we're putting in there at a fast rate.

[00:10:21] Jason: So that would be for your generative irrigations, you know, just running P one s you know, most of the time, like I said, as we'll see between I like to run at least four irrigations [00:10:30] and you know, you could be running up to eight. Or 10, maybe a little bit more up here really fast with your drip P two s.

[00:10:37] Jason: So when we go into more vegetative steering, I like to actually. Keep the same P one that I had. I might need to adjust how much volume I'm getting there at that time, just depending on the plant's needs and how big my dry backs were. But same thing. Eight o'clock lights on nine o'clock we'll start our P one irrigations.

[00:10:57] Jason: Around 10 o'clock we'll be at field capacity [00:11:00] and then we'll start our P two irrigations to maintain fairly high water content. We may not be all the way up at field capacity. You may be just slightly above it, depending on how much you need to monitor your ec. So anytime that we're above field capacity, we're gonna have some amount of runoff.

[00:11:16] Jason: And that typically is gonna lower our ec. As long as the substrate EC is staying high in our PD C then some of that runoff will usually push our EC a little bit lower. Obviously if your EC is below your substrate ec, [00:11:30] or excuse me, If your substrate EC is below your feed, you see, a lot of times it just means that we're feeding a little bit too too less of nutrients.

[00:11:39] Jason: We wanna up our feed ec just slightly. And so it's easy to see that because when you're doing irrigations, if you see your EC and substrate rising, then then you know, hey, the plant has used up more nutrients from the substrate, then we typically feed it on a day-to-day basis. When that's happening, it's obviously gonna be really difficult to employ.

[00:11:58] Jason: Some of the generative crop steering tactics [00:12:00] that we talk about specifically with decreasing the osmotic difference between the plant and the substrate.

[00:12:09] Kaisha: That was a breakdown. M five bmw. Hopefully we answer your question. Let us know if you wanna dig a little bit deeper. Thank you for that. Thank you. Jason, might, I

[00:12:18] Jason: might come just a little bit more as far as P two, you know, if we're pushing extremely. Vegetative. And maybe sometimes if we've got a super small pot size, you know, we're running really big plants, you know, we can [00:12:30] run a vegetative irrigation window for, you know, 10, 11 hours.

[00:12:34] Jason: Kind of the, as, as vegetative as I like to ever go is gonna be a 10 hour irrigation window. That's irrigate first. Time one after. One hour after lights on and then last irrigation, one hour before lights on. You know, if you can't do that, then you probably need to up the size of the substrate just so you can retain some amount of water until the next day's irrigations.

[00:12:56] Jason: However, you know, a little bit more balanced vegetative irrigation [00:13:00] schedule might be an eight hour window. And then typically when we get on the six hour window, it would be like a really balanced irrigation strategy. So much

[00:13:11] Kaisha: to think about as far as irrigation goes. Awesome. Okay. Thank you for that, Jason.

[00:13:16] Kaisha: All right, cipher dropped a question here in the chat, cipher. I'm gonna read it and feel free to unmute yourself if you wanna add, but he wrote, can you suggest a product that has the accuracy of the atmos 14? I'm interested in a thermometer, humidistat that will give an accurate [00:13:30] reading.

[00:13:32] Jason: Yeah, so there, you know, kind of a couple different.

[00:13:36] Jason: Categories of what you're looking for. You know, as far as if it's a handheld, I typically like to go with something that's n i S T certified. You know, one of the best things you.[00:14:00]

[00:14:08] Jason: That are a little bit cheaper, that are typically pretty good. Go in and read the specification manuals and see what the accuracy is on those devices to try and get an idea of hey, does that accuracy match what the Atmos 14 is? So when I'm within a, you know, plus or minus two degrees air on a utmost 14, if I'm in plus or minus two degrees air on a Handheld, well, that means I [00:14:30] could be four degrees off and still be within the manufacturer specifications.

[00:14:34] Jason: So anytime that, you know, we, you know, we get a lot of questions about, you know, Hey, does this need to be calibrated? Doesn't agree with my other sensors, et cetera. You always have to include those plus or minus accuracy ranges on both devices because if we're on the high end of the accuracy on one you know, we're maybe in the top end of those temperatures and So let's say that room's 80 degrees and one of the sensors reading 82 degrees and the other sensor would be reading 78.

[00:14:59] Jason: Well, [00:15:00] both sensors are doing what they're designed to do. So it's nice to get ones that agree as best as possible so we can consistently make those decisions. So, you know, N I S T certified, that's definitely one of the first things I look for. Good known brands. That's one of the things I like to do as well.

[00:15:16] Jason: You know, if you're doing a hobbyist thing, you know, there's some stuff on Amazon, some of those Chinese models they're gonna be probably okay for what you're trying to do. But at a commercial level, it's nice to have equipment that you can really trust when you're doing this. So check out those specs [00:15:30] manuals.

[00:15:30] Jason: And the way I do things is I always try and read as many reviews as possible. And get an idea, Hey, you know, 2000 people had really good success with this sensor. I can probably trust it if every everybody else had a good experience with it. Another category, or thermometers or hemostats, I mean, you're looking at like wall mounted stuff that's controlling an HVAC unit.

[00:15:52] Jason: You know, ideally we're always trying to control our HVAC systems from a canopy mounted sensor. And so, [00:16:00] Typically those types of sensors are gonna come from the automation industry. So building automation management, those type of sensors. And again, tons of that stuff on the market. Look for one that's well regarded.

[00:16:11] Jason: It usually doesn't hurt to spend a little bit more money too. Not that saying that's always gonna get you a better sensor but typically it costs a little bit to manufacture a rugged, high accuracy sensor. And so, you know, in the end, you're gonna have to pay for it a little bit in order to get something that you really rely on.

[00:16:29] Kaisha: [00:16:30] Cipher, you got anything you wanna add or ask further?

[00:16:36] Kaisha: Yeah, you Fantastic. Thank you. Awesome. Thank you for that. Jason. I, you know, do you mind giving, like an overview of the Atmos 14? It doesn't get a lot of airtime on office hours. Do you mind telling the folks a little bit about it?

[00:16:48] Jason: Sure, yeah. I I'm gonna actually just look up. The specs manual specifically for the atmos for our team, because I did say plus or minus two earlier here on the show, and I think it's actually quite a bit better than that.

[00:16:59] Jason: Can't remember the [00:17:00] numbers right off the top of my head, so let me just look up those numbers.

[00:17:10] Jason: I guess I need to log into the internet first, just a minute, everybody. So yeah, Atmos 14. Probably one of the questions that we get a lot as well is that you know, do I need additional repeaters? So the Atmos 14 that AROYA installs is actually, it's a little beehive and then it's got a sensor in the beehive.

[00:17:28] Jason: That's beehive is a [00:17:30] radiation shield. And this is all actually connected to your standard AROYA repeater. So anytime that we need better signal in a room, we need to go a little bit longer range. Atmos four teams work for that as well. And so, it's just a repeater with a sensor connected to it.

[00:17:44] Jason: And so that's the high overview of what, you know, our atmos fourteens are. We do manufacture 'em to be supplied over typically p o e in injection. Right now we're working through some things to make it active P O E enabled as well. So right now it's just a [00:18:00] passive 48 volt DC supply.

[00:18:02] Jason: The reason we're doing that is because, It's easy to run low voltage cap five cable throughout your facility so that you can install this in the best place possible. Cap five's relatively inexpensive. It's lightweight. You probably already have it running all over your facility for your camera systems security camera systems.

[00:18:21] Jason: And then the best part as well is you don't need a certified or licensed electrician to install that type of stuff. So in almost all these cases, we're avoiding [00:18:30] running extension cables. Pretty much every facility I've ever been in, it's like running outta outlets already before they put the AROYA system in.

[00:18:37] Jason: So definitely nice to have that kind of infrastructure, easy installation designed to it. And the, what the radiation shield is doing is anytime that we're in the lighted environment some of those far red light waves that we were talking about are. Increasing the surface temperature of anything that it's hitting.

[00:18:56] Jason: So just like leaves you know, comes right back around to the leave surface [00:19:00] temperature versus air temp. Well, we're trying to represent air temp with the Atmos 14. So if the body of that sensor is getting warmer, then the air temp simply because of the radiation that's hitting it and warming up the solid body of the sensor, then you're gonna have an accurate reading.

[00:19:14] Jason: So that's kinda the whole point of our radiation shield. Pretty common in almost any environmental monitoring systems is having a good radiation shield. So a little bit of airflow through that thing. Just the natural airflow is gonna help keep the body of that at the same temperature as [00:19:30] the air.

[00:19:31] Jason: So yeah, let's jump in and do you want me to share the specs on this or I'll just read through 'em here?

[00:19:36] Kaisha: Yeah. Drop 'em out.

[00:19:44] Kaisha: I also have 'em up. I I have the specs here. We're looking at the temperature specs. Is that what you wanted?

[00:19:49] Jason: Yeah, I was just gonna go over some of the relative humidity and temperature specs. So, All right. Relative humidity for the Atmos 14 Gen two s, we're looking [00:20:00] at a resolution of 0.1% relative humidity.

[00:20:03] Jason: So resolution is just talking about you know, how many decimals out are we taking our reading. So, if we could be at 55.5 percent humidity, or 55.6 that's the resolution on some of the cheaper humidistat. You know, you're looking at either 55 or 56, percent. So nice to have kind of an understanding of where we at.

[00:20:22] Jason: In between those in intervals it's accuracy. It is actually based on humidity and temperature, [00:20:30] but in the operating ranges of. Cannabis cultivation facilities, it's on a plus or minus 1.5% humidity. So, you know, same thing if the rooms at 55% humidity, that means that our sensor could read up to 76.5 or as low as what, 70, or excuse me, 55.

[00:20:51] Jason: Whew. I got kind of wild there. Let's just go to 50% humidity would be the actual room humidity. And the sensor could read [00:21:00] 51.5% and still be within accuracy specs or as low as you know, 58.1%. So always keep that in mind. And typically the, a lot of the sensors that I see, some of, one of the most common sensors I see out there is actually on a plus or minus 7% relative humidity, which is.

[00:21:19] Jason: Kind of just way too far off to be even making much value from those readings. So nice that I think super tight as far as those those accuracies. And [00:21:30] for, let's see, for vapor pressure deficit obviously that's gonna be based on the humidity and the temperature accuracies, but looks like they already did the math for us.

[00:21:40] Jason: So in the operating ranges of cannabis, we're looking at Five to 0.2 accuracy in that V P D. So, same thing there. Resolution, in this case, we're looking at 0.01 k p, I do believe in AROYA. We actually round that to 0.1 k p a. So keep that in mind that sometimes when you see your charts that look [00:22:00] like stair steps that's basically just rounding off the numbers coming in from the sensor.

[00:22:07] Kaisha: Fantastic. Thank you for that, Jason. And actually this is a perfectly timed question that we got from Kenny Keefe over on YouTube. They wrote in is one climate station in a 20 by 30 room enough or should I do two?

[00:22:19] Jason: Yeah. So 20 by 30 room. We're looking at 1200 square foot. Kind of our run of the mill Ill suggestion is one at most, 14 per every [00:22:30] thousand square foot.

[00:22:31] Jason: Obviously if I have a thousand square foot room that's like. Weird dimensions, then we're going to we're gonna want two of them in there, but, so let's, you said 20 by 30. Excuse me. So that's 600 square foot. And so one at most 14 should be pretty adequate. As long as you're making sure you get that in the canopy height.

[00:22:50] Jason: A lot of times it's nice to raise it up a few times as those plants are getting bigger, just to make sure that it is, you know, at the top of the canopy, you know, you're not getting blocked [00:23:00] airflow by being. In the meat of the leaves, and yet you're not, you know, two or three feet up above the canopy getting readings that aren't representing the the canopy.

[00:23:12] Jason: Kaisha, did you say you found the temperature accuracies on there? Cause I can get to

[00:23:16] Kaisha: that. I had it. Hold on. I pull it back up.

[00:23:23] Kaisha: Oh, where'd you go? All right, so, We have here for temperature [00:23:30] accuracies, plus or minus 0.2% degree two degrees Celsius. Is that what you're looking for? Resolution 0.1 degree Celsius.

[00:23:41] Jason: So I'm gonna convert that for those of US Americans here,

[00:23:51] Jason: that's gonna be about 0.35 degrees Fahrenheit.

[00:23:55] Kaisha: All right. Bilbo dropped a couple questions in the chat. [00:24:00] Bilbo, you wanna mute yourself or you want me to ask it?

[00:24:05] Kaisha: I'm just gonna start reading. Okay. Yes, do it. You want both of them? Yeah. Start with your first one

[00:24:12] Bilbo: when calibrating an irrigation skid. I've experienced different readings when I calibrate each injection. Ingredient injection individually versus the entire line as a group. The deviation is approximately 100 to 150 ppm.

[00:24:29] Bilbo: And do you [00:24:30] have any insights or have experienced anything similarly? The probes that are reading that PPM slash EC have been recently calibrated.

[00:24:40] Jason: Yeah. You know what? That is to be expected up to a certain degree. Obviously as those ingredients are interacting, they're going to be changing the electrical connectivity of the signal that most of those sensors are using to read that.

[00:24:55] Jason: And so typically, you know, when we're in an ab ingredient in a b ingredient, [00:25:00] they, a lot of times they won't add up. So if you know, we're at say, five EC of our base and maybe two ec of our Of RP component. A lot of times, you know, we'll see that a little bit higher or lower. The one thing to kind of make sure they're obviously, and it's pretty easy, is just making sure that the nutrients are mixing into solution good enough that we're not seeing some fallout so we definitely don't want have a precipitate.

[00:25:24] Jason: And that's usually, well, that is why our ingredients always come in two parts [00:25:30] and that's why we need to make sure we're having. Good mixing chambers in between any of our dosing systems to make sure that all of those nutrients are fully suspended in solution. Cool.

[00:25:44] Bilbo: And does the AROYA system have a pro provision now or in the future to incorporate an infrared sensor to monitor or track leaf surface

[00:25:54] Jason: temperature?

[00:25:56] Jason: Right now we do not have a leaf surface temperature that [00:26:00] that you can get with the AROYA system. I have played with them quite a bit in the past. Kind of just comes down to some list logistical challenges is one of the reasons that we haven't put the energy to pursue that as a commercially available option from aur.

[00:26:14] Jason: Thanks.

[00:26:16] Kaisha: Those are great questions. Bill Bow, always good to see you. Thank you so much for that. All right, we got another question from Iron Armer, also asking about some future plans from AROYA. So they wrote in, does AROYA have any plans on introducing a product that would be able to [00:26:30] integrate your HVAC and dehumidifier system to be controlled by the Atmos 14?

[00:26:35] Jason: Question. We've gotten tons in the past. And you know, for me, the, probably the biggest challenge is that right now our Atmos 14 limited readings are limited to three minutes. So every reading comes in three minutes and that's just not enough to make good HVAC changes. The best HVAC systems are used in p i d loops to make sure that they're continuously trying not to overshoot their set points.

[00:26:59] Jason: [00:27:00] And and. So right now, probably not in any of the near future. We, you know, we. Might have the opportunity to turn up some of the, those data reporting speeds. We're not currently working on that right now. However, we do have an api. So, I've worked with a number of clients that have set up some types of integrations, taking the data right out of AROYA.

[00:27:20] Jason: So, API basically just asks our server for the data Our server replies the most recent 500 data points for every sensor [00:27:30] in in a facility, and then they can start doing information with that. What I do like to do with our Atmos 14 as far as HVAC stuff is making some programming that validates what your HVAC sensors are saying.

[00:27:42] Jason: So even though I'm only getting a reading every three minutes not enough to make a decision, it's enough to throw a red flag if it is. Significantly different than the reading from your HVAC system. So obviously being that the Atmos 14 is pretty damn reliable and[00:28:00] it's extremely accurate as we just went over, it's nice to use that as a checkpoint and say, all right, maybe I do need to invest in a better HVAC sensor, or now is the time to pull my wall mounted HVAC controller and make sure that the sensor is in my canopy.

[00:28:15] Jason: So, as far as you know, other types of integrations got some people using the API for pulling water content and easy information and doing it as they please with it. So that's one of the beauties of the Open api. And you know, why we don't support necessarily [00:28:30] the ways and the technical background on how you could build that programming, any of these larger facilities.

[00:28:36] Jason: Some of the MSOs that we work with, they have dedicated. System engineers, IT teams that are capable of understanding how it's a very basic, it's a standard rest API system. So.

[00:28:49] Kaisha: Fantastic. Thank you for that, Jason. Yeah, like, AROYA has got a lot of functionality. There's a lot that's possible with the way we have our system set up, so we always appreciate these kinds of questions coming from folks.

[00:28:59] Kaisha: Thank [00:29:00] you for that. Bilbo wrote in the chat here, that's a whole separate business. Yep. We're always watching it, so Awesome. All right, I'm gonna keep it moving here. Got a question here from Cuban se they wrote in. Heard its best to increase pH at the end of flower in Coco, say 6.0 to 6.2. I have always just run 5.8, 5.9 pH clone to harvest.

[00:29:24] Kaisha: Is there a pH chart you'd recommend to see the value in increasing? The reason I [00:29:30] ask is all the pH charts online are different, so how to be sure which one is the most accurate. Thanks guys. What advice do you have for Cuban se.

[00:29:39] Jason: Yeah. So, yeah, I actually don't mind the pH rises up a little bit kind of specifically exactly in the ranges that you were talking about.

[00:29:47] Jason: And let's see, nutrient availability by pH I was actually just looking at these on Tuesday. I did some instructing down there in Humboldt County. And I was bringing this up [00:30:00] to talk a little bit about how it. Changes nutrient availability to the plant when we're at different phs. And one of the reasons that it might be, you know, those charts that you're seeing are so much different is it's very dependent on the substrate that we're in.

[00:30:16] Jason: So definitely don't use the soil pH chart if you're in coco and don't use the rockwool pH chart if you're in Coco. For examples, and I don't know necessarily if I have a direct.[00:30:30] Preferred link for the Coco one. pH chart for Coco. I'm just gonna Google it and see if we find one that we like. And actually I might jump on here and share with the audience so that they get an idea of why we're talking about this.

[00:30:49] Kaisha: We do love an overview, Jason.

[00:30:56] Jason: See if we can build a gnarly feedback loop when I joined the call.[00:31:00]

[00:31:05] Jason: All right, let's chair.

[00:31:13] Jason: So this was my search term between availability pH chart coco, and.

[00:31:21] Jason: Some of them don't do a great job of labeling specifically, which, what they are for. You know, one of the easy ways is also [00:31:30] to kind of just look at where those nutrients are at as far as the pH goes. I'm just gonna pull up a few, and if I don't find one for coco, we're just gonna talk a little bit about how it affects plants.

[00:31:49] Kaisha: Lot of options out

[00:31:50] Jason: there. There is, some of them are nicely colored and some of 'em are a little bit different shapes than others.[00:32:00]

[00:32:03] Jason: One sw.

[00:32:05] Kaisha: So if you encounter discrepancies between a couple of different pH charts, like what's a good rule of thumb for that? Pick a number

[00:32:12] Jason: in the middle. Use the more reputable one. Okay.

[00:32:18] Kaisha: There it

[00:32:18] Jason: is. That's what I would do. All right. I didn't just quickly find. Yes. So don't do what I'm doing where I'm just pulling up one of the first easy ones to read that I can find [00:32:30] this one is for soil.

[00:32:31] Jason: I, sorry, I couldn't find the coco one real quick, despite by browsing here in a few seconds. But why does this matter? Why does it work to let it rise a little bit towards the end of flower? Basically, so at specific phs, the plant has better or worse, Solu ability to macro and micronutrients.

[00:32:49] Jason: So up here in the top, this chart with stand nitrogen, phosphorus potassium, and then getting into some of the micro sulfur, calcium, magnesium, et cetera. And as you can see, some of these [00:33:00] nutrients are much more available to the plant and low phs, and then some of them are more available to high phs.

[00:33:07] Jason: And for the bulk of the growing cycle, we want. To be able to have some availability from all of this. So we're gonna be kind of just riding the line right there. Where. We can see that. All right. We've got just a just starting to get on the edges of specific ones. So the low edge of maybe phosphorus and calcium, for example.

[00:33:27] Jason: We're pretty close to middle [00:33:30] range iron. We're actually at the high end. So, you know, if we are getting towards the end of flower, then wouldn't we let that pH rise a little bit? We're just gonna change How the availability changes to the plant as well. And so there's gonna be a little bit better balance of nutrients available if we go up, say, 0.2 points.

[00:33:49] Jason: You know, as far as in application you know, you're not gonna huge see huge changes in the plant's response to this type of activity. But you know, if it, if you're doing it and you have had [00:34:00] success, do it. Keep doing it.

[00:34:04] Jason: And

[00:34:05] Kaisha: yeah, if anybody out there does find a really good reliable pH chart specifically for Coco, feel free to let us know. Give us your recommendations. We do appreciate the feedback. All right. Well folks, we are gonna actually hop off a little bit early today, but wanted to make the announcement y'all are in California.

[00:34:20] Kaisha: Next week is the big show, hall of Flowers, span of Rosa. You're for sure gonna see me and Jason walking around. Right? So yeah, [00:34:30] if you're gonna be there too, let us know. Hit us up so we can come by, say hi. If you see us come over and say hi. But Jason, before we hop off a little bit early today, anything else you wanna say,

[00:34:42] Jason: have a great day.
