[AUDIO Only] Office Hours LIVE Ep. 40: Coco, Feed EC, Mold, Hardware, Plant Pot Proportion and more!
Mandy: Hello.
Hello.
It's Thursday, 4:20 PM Eastern.
That means it's time for office
hours, AROYA weekly session for
cultivators to hear from the experts
and talk to each other about what
they're seeing with their grows.
My name is Mandy and I'll be
covering for our lovely Kaisha today.
She's representing AROYA
out at MJ Unpacked.
So if you're out at Vegas at that
event, be sure you connect with her.
We're also gonna be out out at a
couple of conventions coming up,
like Hall of Flowers and MJ Bizcon.
It's super exciting to be a part of
such an industry that's growing so fast.
So today we're actually here for episode
40, so we're over live on YouTube.
So make sure you post your
questions for me and I'll make
sure I get those to the guys.
If you're live with this here
and you have a question, you can
type it in the chat at any time.
If we do choose you, you can go ahead and
ask your question or I can ask it for you.
But today we're here with Seth
and Jason live and on the air.
Hey, what's up guys?
Seth: Hey.
Hey, Mandy.
Hey.
Mandy: Good to see you.
How's your week going?
Seth: Good.
Yeah, it's it's pretty nice outside here.
We finally got a little rain.
Mandy: Nice.
All right.
Little turn of the seasons
happening soon over there.
That's awesome.
Love to hear about it getting
some more people joining us.
Welcome.
Welcome.
Hi, Laura.
Well, yeah we had a couple of questions
come in over the week and we had
a bunch from Instagram last week.
So, you guys have any other
messages before we just jump right
into the crop during questions?
Seth: Let's get started.
Yeah.
Mandy: I love, I love the game faces.
Let's go you guys.
Alright.
Our first question came in
from Rich over on Instagram.
This week.
He wrote, I'm looking into
getting a tent to store my mom's.
I also plan to use it for
root cuttings and to veg out.
Do you have any advice before I get
Jason: started?
Make sure you've got some
airflow in the tent is definitely
one of the starting places.
Make sure your lights
aren't overheating the tent.
So sometimes, you know, just a good
exhaust fan as well as new exchange
fan either or mixing fans in there.
That's probably gonna be
the number one things.
Other than that, it's just like having a
little sealed silver room for that stuff.
And it's a great idea to kind
of keep contamination down
from from your mom's, your
Seth: little cuttings.
Yeah.
And you know, just remember like if
your veg plants in there, you don't
have any separation between your
moms, your cuttings and your veg.
So, if for instance, your mom's
get any kind of pests in them,
your gonna have some problems
with your clones and your veg too.
So in an ideal world, you might want
three tents for that kind of purpose.
And then the other thing is just I
was like to remind people, you know,
as far as contamination goes, never
go backwards in the life cycle.
If you go in and water your moms and
check your clones and do your veg
watering in the morning, don't go back in
there after you check your flower room.
You know, simple protocols to help
keep your place clean, go a lot
farther than trying to spend a lot
of money on technology to do that.
Mandy: Awesome.
Thanks guys.
We had another question come in from
our friends over at River City Growers
they wanna know Aqua Lab aside.
What's your favorite method for measuring
dried or cured finished product?
Jason: Aqua
Seth: Lab.
Well, when measuring it, I like
to use a scale personally.
Aside from that, I mean, you
can really get pretty scientific
and try to dry it down to almost
absolute zero, weigh the difference.
That's gonna be pretty destructive
on your, your product though.
So outside of Aqua Lab, the
snap and the smoke test, I guess
is what I always went with.
Jason: Yeah, and I mean, I hate
to mention it, but some people
have used wood moisture sensors.
I, I mean an application.
That's probably better than
not doing anything at all.
I don't know how many steps better
it is, but yeah, my, my favorite
and probably just because I have
got access to it, is in Aqua Lab.
If you are processing lots of
product, then it's definitely a, a
good route go to ensure that you're,
you're not losing, you know, 1%, 2%
over thousands of pounds of product.
And another thing that I always
really liked about it that has been
a big selling point is the fact
that quite a few of your labs that
do your COAs are using an aqua lab.
So if you use that Aqua Lab, you know
that your product should get the same
results by the time it gets to them.
If it doesn't, you know, just make
sure that that the packaging going
out the door to get COAs is, is
good to keep that product fresh.
Seth: Awesome.
Yeah, absolutely.
I just wanna touch on that too and
just say, you know, there's quite a
few people I work with that haven't,
you know, they haven't taken that
step to in the Aqua, the Aqua Lab yet.
That's an eventual scale out plan.
One thing that has really helped them
though, is getting as much monitoring
equipment as they can afford into
their dry room and then investing in
their dehumidification capability and
the rest of their HVAC to make sure
that their dry room's consistent.
So even outside of water activity,
one place a lot of people are
starting when chasing that is how
well is my dry room controlled?
Are we, you know, looking at seasonal
fluctuations that we have to deal with?
We don't have it sealed off
well enough from the outside.
That, that is just a big thing too.
Getting your processes refined so that
if you can hit the point where you're
competent, that your quality is very,
very close without equipment, you're at
least having consistency in your process.
And that's even with the equipment, that's
what we're gonna be refining, right?
So look at it at all angles.
It's not just to having an aqua
lab or a moisture content meter.
It's also saying, Okay, can I,
can I handle those first few
days when the plants are really
wet and we're dragging down?
And can I do that without drying
it down too fast and creating
kind of a hard outer crest.
So, you know, just focus on as much data
as you can and then attacking the problems
you can see before, assuming that you
need to always spend as much money as you
can and get, you don't always need the
most expensive tool to view the problem.
You might need it to really, really
define it and really get down to
it, but you can do a lot without it.
Jason: Yeah, that's a,
that's a great point.
Actually just earlier this week I was
working with a guy refining some HVAC
systems to the place and he was very
thankful for absolute humidity reading
that we have in the array system.
And if you're trying to spec out how much
more dehumidification capacity you need
absolute humidity is a fantastic tool for
understanding the capacity of new D Hs.
Seth: Yeah, we can actually figure
out how many pints we need, although
then you're gonna wish everything
was rated a metric after that . Yeah.
Mandy: Awesome.
Thanks guys.
We had a question come in over
let's see on Instagram today too.
Bki Genetics wants to know I'm only
running four lights, but looking to
maximize my yields with my space.
I'm excited to introduce the
tariffs 12 into my next run.
Is there anything on our website where
I can get a guide or how to feed and
what to look for to steer either way?
Jason: I don't know if we
specifically have that.
I know in our user manuals and their
onboarding guides for AROYA clients,
we do provide kind of an outline there.
If, you know, you want some,
some somewhere to start that
explains that kind of thing.
So you could check out like one of
the floor Flex expert Instagram sites,
maybe download some groan white papers.
Those are the places that
I would start for online
Seth: resources.
Yeah, I'll definitely kinda expand it.
So Flora Flex Tech support is actually
like, that's kinda one of the lead ones.
They've got a lot of great guides
on how to do it without necessarily
having access to the equipment.
One thing you do need to understand
though is there's certain limitations
without having that monitoring equipment.
So like with the tariffs, with just the
tariffs 12 and the sous application.
You can have some pretty decent success
with success with that small room.
So long as you can really nail
down that consistency in there.
And then, you know, the next le
level is like, okay, how often are
you there to take those readings?
If you can get a reading every
hour, we're gonna have a lot greater
control than if you can get a
reading twice a day, for instance.
So you can't accomplish quite a lot.
Yeah, and, you know, just
kinda look out there.
There's, there's a lot of good information
and you know, a lot of it comes from
sources you, you might not expect.
Like the groin, white
papers are a great resource.
You can go to their website, sign
up, read about crop steering in other
crops, and start to learn some of the
fundamentals behind, you know, What does
this irrigation strategy do to plants?
And then, you know, the more you
understand about that, and if you're
very passionate about the cannabis
plant in our different phases of growth,
you can kind of start to put together,
Okay, here's why we are steering
generatively during this time period.
Stretch.
Here's why we're bulking when
we're bulking, and here's why
we're ripening when we're ripening.
Jason: Yeah.
You know, if you plan to you know, get
bigger than that at some point, you know,
you right in a production facility or
you know, a hundred lights or something
like that size, then I definitely like
the university extensions as well.
Many of 'em have greenhouse manuals
that they provide to their students
that are enrolled in those programs.
Download 'em and, you know, start to just
dive into the science behind cultivation.
I found that really helped me
out when I began cultivating.
Seth: Yeah.
You know, if you, you can read a, a set
of irrigation instructions over and over
and over, and if you aren't looking at
what kind of physiological changes and
morphological changes we're producing
with the plant, then you, you're kind
of just waiting to see what happens.
Right.
You know, it's, it's kind of
in, in, when you're in business.
Trial and error experimentation
is really, really expensive.
We all know that.
I will add to that though, if you are,
you know, working off of a caregiver
model or some legal cultivation,
definitely hit up our sales there.
You might be surprised with some
of the people we're able to help
out as long as they have the
proper licensing in their area.
Great.
So
Mandy: there's a couple of different ways
you can approach looking for resources,
but it's all about kind of having an
understanding of horticulture Yeah.
And the science behind it.
Mm-hmm.
. Awesome.
Thank you guys for that.
We did have a question
come in over on YouTube.
Gabe wants to know, will the open
sprinkler integration be able
to operate through Xtra as well?
Seth: No,
not, no.
No current plans for that.
Yep.
Mandy: Okay.
Awesome.
Thank you guys for that.
We had some more come in on Instagram.
Okay.
So we had a user ask about
different thyroids the infectious
entities that affects plants.
They're asking about do we
know all of all 15 of them that
typically affect cannabis plants.
Do you guys wanna talk about some of them?
Some of the most detrimental
ones that you guys have seen?
Jason: Yeah, I mean, so probably
way more than any other thyroid
that we hear about top blant.
And you know, over the last
few years it's definitely been
fairly destructive on some crops.
The fact that it's, it does take a
lab to verify that it is hop latent.
Typically you'll see some plants
being gutted and not all plants are
symptomatic, even if they are infected.
And so it's, it's a tough one.
Definitely worth worth getting
your mom's tested before you make
large number of cuts and being
very diligent with cleaning.
Deer cutting tools.
Seth: Yeah.
You know, full fore foreclosure.
I'm not a certified or licensed
or . I have some plant pathology
education, but I can't rattle off
15 s for you off the top of my head.
At the end of the day though, when we're
talking about production systems, you
know, we, we have a certain limit to how
we can treat different things, right?
Like, if you've got hop latent,
what are we looking at doing?
Well, hopefully putting
something into tissue culture
and completely ning the facility.
So at the end of the day, you gotta
look at, okay, how much is it to
you know, Combat this vi, this vade.
And what does it take?
Well, at the end of the day, it
takes cleaning out the facility.
It also takes that tissue culture
clean up, which is difficult
cost and time consuming.
Can it be worth it?
Absolutely.
But then going on from that, you
know, the more important thing
with VIS is to look back and say,
Okay, where did it come from?
How did I get it?
You know, I mean, before we started
to see hops late, you know, one of
the bigger ones was bringing in mites
or root aphids or, you know, all the
results of bringing a potted teen into
your facility from another facility.
Well, the same's true of the virus.
And at the end of the day, we can
explore each of those thyroids.
But, you know, cleanliness and
avoiding exposure is really the
only way to keep him outta your.
Good notes
Mandy: for people out there
who are looking to avoid those.
We had a bunch of questions come in
over on YouTube in just a minute.
So Jason wants to know, Huh?
Another Jason out there.
Hey, AROYA team.
I'm the DC for a license
producer in South Africa.
I was wondering if you have any
thoughts on pollination prevention
and high temp in greenhouses and
how can I get AROYA hardware?
Jason: Yeah, let's start
off with the AROYA hardware.
I not positive we can sell
in South Africa right now.
I think I'd, I'd have to check with
our team and some of the licensing
on our radio for those devices.
We'd love to get you some systems.
So, you know, call our sales team
and, or I can check on check on
if that's an area we can sell to
as far as reducing pollination.
We'll start off with that one.
We'll talk about high temps ways
to combat that in a greenhouse.
So my favorite way of Avoiding pollination
is pressure positive greenhouses.
So in a lot of greenhouses that
we see, traditionally older school
designs, they will have exhaust fans.
So this is going to create
a negative pressure box.
That's what's pulling the
air through the, the intake.
A lot of times that's a pad.
And so if we actually run pressurizing
fans, then we're not creating a vacuum.
So any of the leaks in our greenhouse, if
we are negative pressure, they're gonna
pull in things like pollen, pasts you
know, dust, any of that type of stuff.
And a lot of the newer greenhouses,
especially high tech ones, we're
running positive pressure in there.
So that's my favorite way of waiting.
Pollination.
What, what are your thoughts there?
Seth: Yeah, yeah, I
mean, I completely agree.
Treat your greenhouse like a flow hood.
You know, pollen can't
move upstream in airflow.
So if we have airflow pressurizing the
greenhouse, we're also not only, you
know, Pushing air out of, you know,
the bigger or offices or vents and
everything, but even the small parts
that are really difficult to seal up.
And that can not only help with pollen,
but things like threats and mights
and other stuff that's trying to
crawl in from the outside, you know?
And then the other side of that I think
is starting to identify, you know, where
do your pollination problems come from?
Are you within a mile of a,
a traditional hops field?
Are you really close to
a bunch of outdoor grows?
In my experience and maybe this is
personal, you know, I found that when I
had pollination issues in the greenhouse,
usually that was from hering plants.
And unfortunately, I would find
that if I was grown, say seven
different strains in there, some
of 'em might, you know, throw a.
There any kind of herma trait
statements at different times.
So I might have some
that like to do it early.
So then, Alright, well I'm seeing some
pollination in some part of the greenhouse
around week five, but then I've got other
ones that drop it week seven and then I
don't really see like full seed formation.
I see little seedlets that are,
you know, don't even have a
developed embryo in 'em yet.
So really look around and see, you know,
is it outside or is it happening inside?
And especially sometimes when it happens
early and without a lot of prevalence
with those hering plants, we can see
a lot of seeds deep inside the bud
that get set before we enter bulking.
So really, I mean, yeah, there's
some good tips to avoid it.
One of the better ones though,
is really trying to figure out
exactly the source of that pollen.
You know, it's kind of like we talk
about hops laton just recently, well,
if you can guess it came from hops
because here in the northwest we have
a few regions that are really good for
growing hops and happen to have a lot of
people that wanna grow cannabis there.
So you add in, you know, the
recent push over the last decade
to establish hemp agriculture.
And we have a few lo locations
in the Northwest that are just
a perfect environment for that.
And then at breeding and the
traffic of clones and the lack
of certification regulation for
the clone industry right now.
And now you kind of get to where
we're at, so, always try to
find the base of your problems.
Yeah.
Jason: And I think we can lead into his
next question here is obviously to help
reduce any her mathematic trades, you can
decrease some of the, the stressor points
or beyond stressor points of your plants.
So one of those would be heat in In a
greenhouse, and I'd imagine down over in,
in South Africa, that is a real concern
a lot of, lot of portions of the year.
So, couple ways to, to deal with that.
And we probably just talk about
the, you know, the typical
equipment ways cable vents.
If you've got riffs that can pop
open, that's gonna naturally allow
the hot air that's rising to escape.
So rather than just being a
vertically exhausted greenhouse
or a vertically or excuse me,
horizontally, exhausted greenhouse or
horizontally pressurized greenhouse,
you can run those, those fence.
If you are positive pressurized,
which is awesome, typically
you'll see less gradient from
front to back of the greenhouse.
You may not even have a front or the back
of the greenhouse like you would with
a, a horizontally exhausted greenhouse.
So make sure that you've got nice
cold water in your pad pumps.
If you've got well water, that's ideal.
One of the things that I did try when we
got, we got beyond our cooling capacity
was actually put ice in the pad pump.
And that made a pretty significant
difference on a day to day basis.
Not probably what you want to do, but you
know, if you run practical to two or three
days in a row that are, are way beyond
what you can handle, give it a shot.
Seth: Even getting a water chill in
there in there can help a lot, honestly,
especially if you've got a good return
rate, you're not evaporating too much.
But you said though, water quality's key.
If we're pushing a lot of hard water
through our pad vent, that means
we're gonna have to clean it a lot.
And also from personal
experience, if you do have hard
water, don't turn off your pad.
Vent through that run.
, all that scale's gonna
shoot outta the pad.
Vent all over your crop.
Jason: Blackout.
I, when I did programming on some
local greenhouses, we, I would
basically have a high heat setting.
So it was through a flag.
And when I got, you know, 15 degrees
over my set point, I would basically
go into an emergency heat standpoint.
And what I'd do is end up closing
the blackout a certain amount, right?
So, sure I'm jeopardizing some of
that free light that I could be
getting, but when my heat's going
that far up, at that point, I'm just
trying to, to salvage plant health.
And so I know I'd close it like 25%
if I was 15 degrees above that point.
Go to 50% if I was 20 degrees
over set point or all the way.
Those probably aren't the exact numbers
that I used, but just trying to evaluate,
hey, how much can I sacrifice in order
to, to keep that temperature down?
And obviously a lot of good blackouts
are, are silver on the top side.
And they'll help just reflect any of
that, that solar radiation coming through.
If you do have the roof, you know,
and a reflective blackout, it's gonna
play a huge factor in, in keeping
the, the lower portions of it.
Cool.
If you have hydraulic bench heaters,
a lot of times you can actually
run that cool water through the
hydraulic system and keep your root
zone even cooler as well, and that,
that can play a pretty big factor,
especially if you can't keep the air
Seth: temperature down.
Yeah.
You know, and one thing I always
find myself reminding cannabis
growers about is, especially when
you get in the greenhouse, utilize,
I mean, we always talk about plant
empowerment as being a good resource.
There's several other resources
about greenhouse growing and.
Well, I mean, there's a whole series
of textbooks, , not, not one series,
but several that have been written over
the years that talk about how we can
calculate airflow needs, humidity needs,
and how, you know, greenhouse designs.
So it doesn't matter what we're
growing in the greenhouse, if
we have X amount of humidity and
X amount of heat to get rid of.
Those are calculatable things,
especially when we know some of
the environmental conditions.
So if you look into that a little
further, you can really start to
analyze for yourself, like, Hey,
here's my, here's what I'm stuck with.
Now.
I'm seeing way too high
bpd, way too high heat.
Based on these changes I'd wanna make,
which one might be the most effective
based on movement of BTUs based on, you
know, gaining or losing humidity in there?
What do we want to achieve?
And that's probably the best way
to go about it, to be honest.
Just try to learn as much as
you can about greenhouse design.
That way you're not throwing
money at a problem that.
You don't have quantified, you don't know
how much money it's gonna take, start
there and then go forward, You know?
And then the other thing too it's
gonna sound low tech, but hey, if
your heat is way up and you just can't
keep your vpd under control we're,
we're just joking about this before
the show actually sounds low tech.
Get out there at the hose
and hose down the floor.
You know, if you got a big concrete pad
in there, get it wet a few times a day.
Unfortunately, to keep your
vpd in check at 90, 95 degrees,
we need like 80% humidity.
So, you know, just follow your vpd chart
and start to make decisions based on that.
Mandy: Wow.
Thank you guys.
That was super educational.
We had about five questions come in in
that time, so, and a couple of shoutouts
Mista says, thanks for the reply.
We'll be in contact for sure.
We have a question from Grateful.
Have you ever seen or used scales
under rockwool to determine drive
back percentage and shot scheduling?
Jason: Sure.
So let's talk about
load cells a little bit.
In Dr.
Greenhouses, you'll see
'em all over the place.
People that are running, you know,
the high, high bay greenhouses doing
cucumbers, peppers, tomatoes, you know,
they'll be running 15 foot high plants.
They'll be running the entire bench
on load cells to evaluate water usage.
So, on a really large scale, that
load cells are a great way to do it.
When we go to evaluate our sensors
or do new sensor design, we're
always cross-referencing it with,
with the scale in order to, to get
those, those dry downs and stuff.
So, In, Yeah, in application.
It's fantastic.
When it comes down to deploying
those type of sensors, it
can be a little bit trickier.
Obviously the cost of doing
a, a load cell setup in a
greenhouse is it's pretty tough.
There's, it's, it's a lot of money that's
going into there, and if you're looking
to retrofit, almost never pays off.
And that's where we see the
effectiveness of wireless sensor.
Like the Terras 12 is, anybody can get
that purchased, you know, if they're
in a 5,000 square foot greenhouse or
indoor, if they're in a hundred thousand
square foot, they can have that system
up in a day without any engineering.
You know, any saws, any any construction
workers revamp in that place.
So if you, if you've got 'em,
absolutely take advantage of 'em.
You know, as far as the principles.
Pretty much the same
evaluating water content.
You know, another advantage that TRA
12 s do have is you get temperature
and electrical connectivity in
those substrates so that obviously
you'd have to evaluate somehow
else if you are using load cells.
Seth: Yeah, and you know that,
I think you nailed it there.
It's really an implementation problem that
using wireless technology overcomes here.
You know, if, if, how many load
cells would you need out there?
If you had one per hundred square
foot, that would be so many load
cells in a given facility and the
cost is gonna be so much greater.
But currently, right now, where they
come in handy, honestly, is cloning.
So where your dry rock
will slab, wet it up.
Weigh it.
And then now, you know, every
gram is a milliliter of water.
We can figure out how much water
those clones are pulling out.
We can watch 'em getting lighter.
We can watch 'em not getting lighter.
That's, that's kind of at this point
where scales and load cells come in.
The other thing is you know, over
the years looking at it, if we, we've
gotta correct our measurement on
a load cell because we're building
weight in the plant above it.
So at the end of the day, it is a
really cool measurement, but all we
can really look at is the difference
between right after we water.
And then later in the day and always
know that we have a little bit of
inaccuracy because we have a changing
by the minute weight above the pot.
Jason: Yeah, that's, that's what I was
gonna mention as well as you know, the
high tech growers that have used them
in traditional horticulture, they have
biomass accumulation models in which that
they're using to offset that load cell.
Unless you really wanna dig into the
science of it and you know how fast
your plants grow as far as their,
their carbon buildup, then it's gonna
be quite a bit of work to get there.
If you're running a new genetic you
know, when you're dele, these are all
weight attributes that are gonna adjust
the, the load cell and, and you're gonna
have to account for those when you're
using it for water content if you want.
Seth: Yeah.
And, and I mean, a way I like to look
at it too is you know, using the load
cells can kind of go back, you could
compare it to trade to calculate total
transpiration across the greenhouse
based on, you know, leaf surfaces,
bpd, and approximately leaf area index.
Well, I know my leaf area index is
gonna be a very, very rough estimation.
In fact, I'd just say it's a guesstimation
because it's gonna be wildly inaccurate.
So I know if I'm calculating
transpiration rates and water
usage that way, I'm gonna be.
Looking at pretty wide averages isn't
something that's very approximate, and
that's kind of the same way we look at
that load cell, unless you spend the time
and money to take it to that next level.
And right now, most cannabis producers
are too busy trying to make money.
I, I will say, your, your time is
better spent building your business
and making sure it's gonna be there
next year and the year after than it
is pursuing expensive research in your
little fac in your not little, but
any particular facility right now.
It's, it's just expensive.
You know, don't, don't take chances unless
you're willing to throw your weed away.
That's kind of the way to look at it.
Well,
Mandy: when you put it that
way, it's an easy decision.
Thank you guys for those questions
that are coming in over on YouTube.
We did have a couple more.
John wants to know my new stock
is in Pure Coco this next run.
As for your advice, since there's a
ready to roll you said recently it takes
longer for full spectrum l e d to rip in.
Can you gimme like a ballpark?
Jason: Not, not confidently without
knowing genetics and environment
and light intensity at that canopy.
I, you know, maybe if, you know, you're
riping it over seven days, you might
see 10 to 12 days of ripening, but
it's gonna be quite genetic dependent.
You know, when we look at that,
that spectrum change, it's, it's
affecting different different
chemicals in there, right?
So when we look at Cyros, cryptos
those are secondary tabloids.
And the concentration of
those is, is widely different
from cultivar to cultivar.
And typically those are the ones
that are modifying how quickly we
Seth: ripen up.
Yep.
And I, I wish I'd prepared some
pictures for this question.
I have seen many, many examples of growers
that have both i d and L E D rooms.
Typically they're running a
little bit longer, sometimes
in that four to five day range.
Some strains I actually get quicker
under their LEDs with full spectrum.
Like Jason said, it's genetically, it's
really hard to make that or tell you for
what you're growing, what's gonna happen.
But back to the pictures just because
of the spectrum and type of radiation
that's hitting those buds and that plant
in general throughout its life, a lot of
plants will look morphologically different
under an L E D versus an a, an hps.
So like, and what I mean by that is
when we look up the L e D might just
have a little bit different shape.
We might have a taller bud with
the i d in a shorter fatter bud
with the L E d, we might have a
little slightly different color.
We might have a little darker green with
the i d versus the L E D or vice versa.
So there's a lot of little
differences to look at.
And then even when we get into the
world of LEDs, . You know, do we
have a far red supplementation?
Do we have UV supplementation?
There's a lot of factors in that
spectrum that are gonna influence that.
Jason: And this, this is a
really fun area of study.
Yeah, for me, because traditional
and agriculture, there hasn't
been a ton of energy spent in the
sciences of was photo morphogenesis.
And that would be talking about
how plants, physiology changes
over time in respect to The light.
Mm-hmm.
, and that can be light intensity, like be
intensity combined with spectrum as well.
So really neat things that we're seeing
especially moving to LEDs and we see
some LED manufacturers doing adjustable
spectrum and their LEDs as well.
So if you are using adjustable spectrum,
probably good to start doing some AB
testing on rooms and, you know, playing
with the, the blues maybe earlier on.
And then playing with some,
some infrared to see if you
can't trim down your right time.
Seth: Yeah.
Then make sure you know, I mean, back to
any kind of experimentation, make sure you
document it properly, you know, if you're
gonna be playing with that document.
Every change you've.
At every time.
And then also, you know, we're
talking about the effects
of light spectrum on plants.
Go back to it.
We've gotta look at that holistic run.
So if I just change the spectrum for
two weeks in the middle of the run
and I wanna call that a difference,
or one week or two days, I really need
an extended period of time for that to
actually morphologically change the plant.
Mandy: Awesome.
All super important
things to keep in mind.
John, I hope that answered your question.
Yeah.
Follow up with any other
questions you have.
Just for asks, what pH ranges have you
guys found most successful in rockwool?
Jason: 5.6.
Seth: Yeah.
5.6.
5.7.
5.8.
5.9.
Usually right at 5.6.
Going in though, cuz you don't have quite
as much variability as you would say co.
Jason: Yeah.
I'll add one caveat on that.
When we are wedding up a rockwool that
has a surfactant in it, a wedding agent,
then sometimes we'll actually wanna go
just slightly lower because typically
those surfactants are more basic.
And so if I'm, we up rockwool for
the first time, a lot of times I'll
go in it like five four just to make
sure that I am dissolving the that
wedding agent out of the product.
And then I'll be at that, that standard
5, 6, 5 7 after the the we shop.
Seth: Yeah.
You know, a good rule of thumb
for rockwool or Coco is VDC feed
pH, that's what you're, what
we're typically going in at.
And then if we test runoff, test
the plant, like coco for instance,
if we've got something that's super
salty , well you might wanna rinse it
out a few times per the instructions,
test it to make sure it's good.
And yeah, at the end of the day, I
think best practice is always when
you've got either an old or new media,
wet it up with the solution you're
gonna use, test it, make sure it's
sitting where you want it to sit.
Try to get a little runoff, make
sure you don't have anything that
you don't wanna be planting in.
You know, that's just best
safety practice for your plants.
Mandy: Awesome.
Thanks guys.
Laura had a question.
Laura, do you wanna ask your question?
Sure.
Hey guys, I'm just curious to
know what exactly Coco is made.
Jason: Coco Courier is made out of
coconut husk and it is crushed and
shredded and then it's washed and dried
and sometimes it's compressed into
blocks so that it stores and ships well.
Seth: Yeah, it's a, it's actually
a byproduct of the general coconut
industry that has been around ever since.
They started stripping coconuts can
and sending 'em over and sending
'em overseas, so pretty neat.
Mandy: Awesome.
Thanks.
Super neat.
Thanks, . Thank you.
Yeah, learning, learning things every day.
Back to some of our Instagram
questions cuz we have a ton.
This is a little bit
longer, so bear with me.
What's the easiest way to raise your
substrate ec while generative steering?
So I use smaller shot sizes.
So do I use smaller shot sizes or do I
lower the frequency of irrigation events?
During my P one, I'm currently
doing ten four percent shots
until I hit Mac saturation.
And then sometimes I'll add
a couple of maintenance shots
so I don't dry back too hard.
I'm using six inch Hugo Blocks.
It's been difficult to get
my EC up past two yeah, 2.0.
I'm also wondering if my
sensors aren't working properly.
It's another system that
I won't mention here.
.
Jason: So , yeah, we,
we won't mention that.
Part, either.
Well, I
Seth: don't think we have to
discredit them with this one though,
.
Jason: So a couple things.
I mean, the easiest answer, if
everything else was right in, in
track, then reducing runoff would
be, that's, that's the easy answer.
Couple things going on here, though.
So we're really glad that
you included the details.
You know, if you're running in
a six by six Hugo and you have
to do the maintenance shots then
it's gonna be tricky to do some of
that, you know, reduce and runoff
and, and keeping your ec stacking.
So if your plants are big enough, you
might just consider going in a little bit
larger media you know, possibly into some
slabs and and or run like an eight by
if you don't like slabs for some reason.
I personally love slab.
Yeah, so those, I guess those
would be kind of the, the
more advanced solutions to it.
And then also look at your cdc.
If you're feeding too low, those
plants are gonna be eaten up the
nutrients and they won't stack.
Right.
And so, you know, if you're going in
anywhere under say, two and a half
with a two part salt, then you're
probably just running outta nutrients,
and that's why it's not building.
Seth: Yeah.
And you know, I mean, one really important
factor when you're trying to dial all
this in, especially these shots, and
look at like, okay, how much, how much
runoff can I push and look at, you
know, what my EC is doing after that?
Right now it sounds like there's a
good chance that a lot of the time,
especially with the maintenance shots,
like Jason mentioned, you're just
washing back to your CDCC basically.
And another thing to consider too
is if you are trying to stack it up,
you're, you can't keep up with it.
We didn't come out of veg
with a high enough ec.
Sometimes we gotta up that vdc, you know,
upping from a 2.5 to a 3.0 is a good
place to start if that's where you're at,
which is where, you know, the highest,
a lot of traditional mixes will come in.
Even going up to a 3.5 or a
four sometimes is necessary.
If we've got a plant that
just cannot stack ec, but we
always wanna balance that.
We always need some runoff.
So, yeah, modulating runoff
is typically the way we, we
stack EC on the AROYA program.
Mandy: Great.
Thanks for that advice.
Jason also over on YouTube
has another question.
What's your strategy for plant Dr.
For plant not drying
evenly in our greenhouses?
Overate the slow feeders or underwater,
the strong plant, the stronger plants.
Thanks for any information you have.
Jason: Process review and understand
what's resulting in those inconsistencies
is where, where I like to go with it.
Obviously prevention is ideal, so if
there's places in your cutting processes
that you think you can improve, if you
need to tear out your drip emitters
because they're clogged and not run any
any TOC based additives in the future.
Those, those are definitely
things, you know, making sure you
got enough pressure so that those
PCMs are operating appropriately
across all of the, the plants.
So my first step personally
would be just to review why we're
running into those inconsistencies.
And then obviously if I had to energy
left leftover from that, maybe I
would, I would try to compensate
with, with what we're dealing with,
Seth: right?
Yeah.
So I mean, a few things there.
You know, number one,
we gotta go find those.
We gotta establish, do we have a micro
climate problem in, in this facility
or do we have a irrigation problem?
So number one, if we've established that
the irrigation works, it's consistent.
Alright.
You know, number two processes.
Alright, we, you know, how are
the plants coming out of veg?
Do we actually have consistency?
But you did say one thing that
tipped me off, which is greenhouse.
Now a lot of cannabis greenhouse houses
that I've seen, you know, some of 'em
are changing that, but typically I have
a longitudinal airflow, which means we
have a pretty big gradient from where the
air enters the room and where it exits.
The other side of this is the trend
in horticulture in general, especially
pre cannabis, which is carried into
cannabis, is to install your benches.
Parallel to that longitudinal
flow rather than perpendicular.
And what that means is now we have
irrigation zones that are running a
longitudinal differential across them.
So we have a zone where one end is
drying out faster than the other.
Effectively.
It doesn't sound exciting, but
sometimes in those situations you
know, ideally we'd re reorganize
the room so our zoning was correct.
Well, sometimes we've already
invested all this money into
this bench layout and stuff.
What's the next option?
More zones.
Buy more solenoid.
Zone it off so you can, you know, be more
precise with your irrigation application
and treat those parts of the room that
you know you're having problems with.
But it, but it really all starts, like
Jason said, foundationally, look at
your processes, look at your greenhouse
and actually isolate that problem.
Cuz again, if we have a big differential
and we put in the most consistent crop,
but it's all in one irrigation zone,
then our, our ability to treat any
one plan is kind of out the window.
Jason: Yeah, I I did a video just
on kind of the statistical basis
of population data, and so go check
it out on our YouTube channel.
I think it's called Growth
Behavior or something like that.
And it might give you a couple ideas
on how to identify those issues.
So obviously if you do see a very
clear gradient, like Seth's talking
about it is probably climate related.
If the consistency is spotty based,
then it's probably more likely
irrigation or plant consistency based.
Seth: Yep, that's a good point.
And then we're looking at that too.
You know, remember we're always, we
don't have a sensor on every plant.
We don't have a valve for every plant.
So at the end of the day, we're
always playing a game of averages
and working on a range for every,
every parameter we're looking at.
The best we can do is try to
equip ourselves so we can make
that range narrower and narrow.
Mandy: Awesome.
Thanks guys.
Moving on down our list from our
questions from Instagram this past week.
In our Y Garden is asking I'm looking for
some guidance on Target ec in the first
20, in the first 21 days of Bloom and
target c 21 days until the end of Flower.
Do you guys have any advice?
Seth: What's your EC coming out of Veg?
That's, that's where we'll start.
EC is a very it's not
a static Ranger number.
It's a dynamic value that If we're
gonna approach what's optimal, it's
not even for each strain we're going
down to, you know, each facility.
Do you have h i d, do you have
l e d and then run to run.
How consistent have you been?
Where did you come out of veg
at and what can we expect to
stack up to at these plants?
So some plants, if we come out of veg
at 1.5 or two, once we put those into.
, I can guarantee you most plants
aren't gonna stack up very well
feeding at a 2.5 or a 3.0 because
they're gonna chop through that salt
faster and we can get it on there.
Now, when that's the case
what am I looking to do?
Am I looking to really
jack up that EC right away?
Not necessarily.
I'm gonna go look at plant health and say,
Okay, I might like to be in generative
up in maybe this four to nine range.
That's not gonna happen, this run.
So what do I gotta do?
I've gotta go back to
managing plant health.
And when we're talking about ec, the
biggest thing to remember is that the
plant can adapt to that EC only so fast.
So during stretch, we're
gonna be building up, ideally.
But if we couldn't build up in stretch now
we're gonna be running a little lower in
bulking and a little lower in ripening.
That's just how it works.
So, I mean, I know it sounds
weird that we're always hesitant
to give exact numbers and that's
because there aren't exact numbers.
You know, I could, same thing we were
talking about the same strain under l e d
and h I d I can show you the same strain.
The same guy grew one finishing
out at, you know, over a 10 ec
and then the other one trying to
flush, trying to taper it down.
And guess what?
The bud does look a little different,
but neither of 'em are bad.
And neither of 'em have a heavy
black ash or any problem like that.
So, it really comes down to
your trajectory and then how
well you can be consistent run
to run, to really dial that in.
Jason: Yeah, and I think he's he's
one of our clients up there in
Canada that's got AROYA system.
So set your target ranges and alerts
in your harvest groups and and then,
you know, if, if you don't have time
to be looking at the graph, maybe,
you know, every single morning, then
our system can kind of just help you
keep in in those adjustment timeframes
when you need to make modifications
to that are easy that you want.
Seth: Yeah, and typically, you know,
I, I actually don't recommend that
people set alerts for their ec.
I always recommend you set an
alert for your water content.
Your high EC spike is always gonna
correspond to an over drying event.
And then at that point we just gotta
look at how well did you try it all the
way down to wilting, how far did we go?
And then evaluate the damage there.
Mandy: Thank you guys.
So one love Rebel wrote in on
Instagram crop steering and
larger pots, five gallons and up.
Do you guys have any advice from me?
Any
Jason: general tips, Grow
your plants outside, say big
Seth: plants.
It's all about pot to
plant size proportion.
And then also one thing to
consider about those big plants.
Hey, I, it's pretty cool to like veg
indoors and in May put out a six foot
plant into the ground that, you know,
is gonna get to be 14 feet tall.
You know, the danger, one of the
dangers about that is we tend to see
a lot higher rates of root pathogen
and infection in l plants that are
in a big pot for a longer amount of
time, just cuz we can't get consistent
oxygen penetration into that pot.
So we end up with anaerobic pockets
and depending on your environment,
you could be exposed to fusarium or
pythium or a number of other soil
diseases that we don't want in there.
So, yeah, basic advice if you
wanna do that, you're going big and
then, you know, I, all I can say
is send me pictures down the line.
Mandy: Go big or go home.
That's what I'm gonna say for this one.
Awesome King Green Beast rode in too.
Why are people convinced that
product comes out better when
grown in coco instead of rockwool?
Have you guys heard that?
Seth: Yeah.
I'll touch on that for a second.
Because coco looks like dirt
And I will say there are some people out
there that are running kind of a hybrid
system where they are throwing a lot
of different organic inputs and mixing
up their own soilless mix with coco.
So there may be certain additives
that you can get in there that people
are not able to add to the rock wall.
But man, I I, I need to see some
quantification because a lot of,
I hear, a lot of it, I hear is.
Well, I just feel, and you know, I, I
personally don't think there's a whole
lot of, if I'm running the same nutrient
line in rockwool or coco, as long as I'm
running that, and as long as I don't abuse
either of those plants and they come out
fairly consistent in terms of the way
I grew 'em, I probably, I would defy to
tell the difference, you know, we, we
can go back to those old wine tasting
things where they had the cheap wines
unlabeled next to some expensive ones.
And, you know, even some of the fine
wine people couldn't tell the difference
when they framed it in the right way.
,
Jason: I mean, yeah, maybe it's
better because rock or Coco's more
eco-friendly than rockwool, you know?
Yeah.
Seth: And that, that's debatable too when
we talk about, you know, carbon footprint.
Yeah.
Shipping something across the ocean.
Yeah, like I said, I personally think
it comes down to, it looks like dirt and
it, it has a different feel, you know,
And then on either have their hand too.
You don't typically see many
people running rockwool outside
of a commercial application.
Yes, it happens, but people at home tend
to have a lot more, a lot better luck
watering hand watering coco than rockwool
just because if you miss a day with your
rockwool, we all know that run screwed
or at least the yield on that run is
so the coco better results over time.
Mandy: Huh.
That kind of makes some sense there.
River City Growers also
gonna end another question.
What would the recommended parameters
be for drying and curing, like
temperatures, times relative humidity?
Do you guys have any advice
Jason: for.
Kind of what I start off with without
knowing anything else about what's
going in as far as, you know, product
size or the goals of the facility.
60 to 60, 60 for 10 days.
That's kind of just,
just the starting point.
So 60 degrees Fahrenheit,
60% humidity, 10 days.
Obviously you, it's
pretty tough to hit those.
Exactly right.
You know, the first few days you're
probably gonna be pushing your HVAC as
hard as you can to, to get close to 60.
But if without any other information,
that's, that's kind of what I'd like.
Seth: Yeah, I, that's, that's
a very reasonable goal.
They, my biggest thing to say
there is again, the consistency.
Like Jason said, it might be tough
those first few days to establish
that, but that's where, you know,
dialing your HVAC comes in and saying,
Okay, we need X amount of extra du
capacity for the first three days.
Then we can back it off to maintain that
60 and 60, I think One of the worst things
you can do is dry too fast, too quick
and really kill some of your bud quality
there because it's hard to it's hard to
get that jar peel back after we've really
crunched up the outside of the nu then
throwing it in bins and tumbled it around.
I mean, hopefully we're not beating it
up that much, but hey, it's reality.
If we got 200 pounds of, of product to
pull down from a dry room and if that
product has been dried in away, that makes
it fall apart, we're gonna have problems.
Right.
So just, just that
consistency and being patient,
Mandy: it's so important to be patient.
We had a couple more questions.
It's that simple.
Four 20 is asking when calculating 1%
shot size for coco, do you use US gallon
four liter or nursery trade gallon,
Seth: three liter.
, I try to get the actual
volume from the manufacturer.
So if the manufacturer says a gallon pot,
does it say four liter or does it say
three liter, or does it say 3.78 liter?
So typically just try to get the actual
value from the manufacturer and maybe
look to where, where is your product made?
If we're talking about Canada or Europe,
you know, when they say one gal, it's
gonna be that four liters we're talking
about the us it's gonna be 3.5 probably.
Jason: And when in doubt, major
Seth: it yourself.
Yeah, exactly.
There's there's no crime in that.
Dump it out and measure.
Mandy: All right, there we go.
Anyone on the chat with us,
please submit your questions.
We are rounding out our
hour with Seth and Jason.
We can go ahead and get
your questions asked.
I had one more question from Instagram.
When, when you cannot get your vpd down at
the beginning of flowering what do you do?
What are some what are some
tips you have for lowering p
Jason: d?
I mean, so usually, you know,
temperature, probably you're hitting
the temperature that you want.
So if your VPDs too high, it's usually
because we're having a hard time
getting enough humidity in the room.
A lot of times you will see that early
in flour simply because your plants
aren't large enough to transpire and
add as much water to the water vapor to
the air as you will see later in flour.
So increased humid humidification
capacity would be probably the easiest.
Seth: Yeah, I mean, for a
lot of people I've talked to,
it's come to that realization.
They've hit a room size now where their
small plants can't keep up and it's
actually making that, that first time
installing a humidification system.
Yeah.
You know, sometimes depending
on your, your size of the volume
of the space you're grown in.
Before it wasn't an issue and now
it is, you know, and we see that a
lot with people that move into like
warehouse spaces with very tall ceilings.
Greenhouses particularly because you
have a lot of radiant energy coming
in and actually warming up the air
compared to just having grow lights.
So it's actually in the summer can be
quite hard to maintain that humidity.
So don't, don't be scared to either
buy a humidifier or we go back to it.
If you got concrete floors
in your greenhouse, low tech
spray some water on the floor.
If it's getting that bad.
Jason: Yeah, and you know, we were
just kind of discussing like when,
when you do run into those issues,
if, if it's a one off thing, you know,
it's for, you know, two days of the
cycle, then you may not need to justify
some type of humanification system.
You know, if it's, it's just barely
get something, you know, really cheap
to, to get that humanification system.
If it's a significant impact, it's
happened every time through the cycles
all year round, then then you're,
you're way better financially ahead
just to, to get something in there.
Seth: Yeah.
It all comes back to return on, return
on investment and cost benefit analysis.
If we don't need this all the time,
maybe we can't get around it, but when
it's time for a serious infrastructure
upgrade a lot of times it's a lot cheaper
to take care of the problem rather
than bandaid it for a long time over
and over and throw that labor at it.
. Yeah.
Jason: You know, it's kind of interesting
when we look at the plant life cycle.
So if we look at the room for improvement
it's the largest younger the plant is.
So as our plant grows, our you know,
impacts of making an improvement
to that, that plant environment,
irrigation decreases cuz that plant
has less life left to basically grow
off the improvements that we've made.
So if we can keep things as, you know,
as tight as possible early on, that's
really gonna pay off towards the end.
And vice versa, we have obviously a lot
more plant value as the plant gets older.
So if we can build that value
as fast as possible, then then
we're making the right choices
Seth: in the room.
Yeah.
And then, you know, taking, taking a
second to think about what when you
are making those choices, you know,
prices side, sometimes obviously
there's an obvious winner when I'm
looking at two products, there's
price versus quality or price versus
one on one product versus another.
The other I can't afford, but.
You don't always want to
go as cheap as possible.
Anytime you're upgrading, always
think for the future and say, Okay,
You know, if we're talking about deh,
it's the same thing as humidifiers.
If I'm getting a dehumidifier and I
need to double my capacity, I don't
want one more, I probably want four
more smaller ones, just cuz now I
have a greater degree to control.
The same would be apply to your
humid humidification system.
All right.
In this room, I'm starting to look
at the room size and at the area of
influence that one humidifier can have,
and then also how does it perform?
How consistent is it inside
that area of influence?
Well, In reality, if my room's 2000 square
feet instead of one or two big ones, I
might want a system that has, you know,
12 or 15 different nozzles and access
points that are more evenly distributing
that humidity that's around the room.
That way I'm not just accidentally
blasting the front of one bench,
meanwhile 10 feet back, it's perfect
and 20 feet past that, it's bad again.
So, you know, just really when you're
doing that cost benefit analysis, try to
think of every aspect of that improvement
and that upgrade, not just only that
delta that we're calculating for.
Mandy: Great.
We had a couple more questions coming
over on YouTube, so I'm gonna try
to go through those real quickly.
Gabe wants to know, do you
have any advice to avoid white
mold buildup on top of Hugos?
Jason: I mean, you can
always put a cap on 'em.
That's not my favorite thing to do.
I typically, the molds aren't gonna
affect the plant growth too much if
it's on just the substrate itself.
So I usually don't get
so worried about it.
Obviously, it is unsightly and not the
best thing in the world, but when we look
at how much energy it is to combat versus
how harmful it is to our production,
it's usually towards the bottom of
the list on corrective actions that we
Seth: need to be taking.
Yeah.
And you know, I mean, some to look at
there what is causing the mold, typically
what we'd see is a lot more algae.
Do you have a root drench that you're
doing that has an organic component that
stays behind that the mold can grow on?
What, what's going on there?
Typically that question
comes a lot more from al.
And again with the mold, probably
what I would do afterwards is just
start dissecting those blocks and
saying, Okay, like algae, we could
pull apart a, a Hugo and I can start
shaving it down and show you that the
algae actually isn't competing with
the plant for water or nutrients.
And we can calculate that
the uptake of that algae.
And it's the percentage you're losing in
efficiency in your system is negligible.
You're losing more to run
off than you are to algae.
And then again, that's the reason to go
and at the mold and dissect it, is that
actually like, do I have good roots?
Do I have good root growth, or is this
mold happening because I have root rot in
this top block, in that that dead organic
material is actually what's feeding it.
So look, it's, it's an indicator that
you might wanna look deeper at what's
going on, but just like Jason said, once
you've investigated the problem, I mean,
I've even said this about fungus snaps a
bunch of times, you know, and I do a lot
still talking to coco growers, especially
ones that wanna run compost teas.
You know, and then do a
drench for fungus Nats.
I'm going, Okay, well quit
chasing your tail here.
You're spending money on the compost,
then you're spending money on the drench,
and then you're putting more compost
tea on and you're getting more nats.
And the reality is those, those
fungus nats don't feed on your roots.
They feed on the fungus in your root zone.
So where fungus Nats really do well is
if you bring in organic soilless mix and
you've got decomposing matter in there
and you've got beneficial fungus in your
soil, that's what those fungus nats eat.
So if you're just worried that you see
a fungus nat or a few around, eh, you
might wanna put some sticky cards out.
Start evaluating, Okay, how many am I
catching inside of a certain time period?
At what point do I think there's
so many fungus snaps in here that
are gonna like, stick to the buds
and people will see 'em in the jar?
Like really identify is it a problem
that bothers you or is it a problem that
actually affects quality and output?
You know, And the same can go if
you here's a classic one, switching
from generative to vegetative.
Washed my ec out, ran too much runoff.
That happens all the time.
Okay.
Try to build it back up a little bit.
But I got some burnt tips.
I got some yellow leaves cuz I was
deficient for a few days while I
was trying to get that back up.
The plant didn't like it.
Well those leaves aren't
gonna turn back green.
So part of, part of I guess being a
grower is learning when you need to
let, when you can let things bother
you and when you need to put 'em down
and say, Okay, that does bother me.
But that is not a a factor I need to worry
about for profitability in my system.
Cuz at the end of the day, if you're
too worried about your garden, I
mean, we all gotta go home and sleep.
We gotta have a life
outside the garden too.
And you know, I don't think
anyone's in this to have a bad time.
Most, most cannabis growers are
I find to be fairly passionate
and enjoy what they're doing.
So I like to do my best to
keep it that way for 'em.
Mandy: Thank you guys for that.
They did have a follow up.
They don't have any organic inputs and
they've never appeared on my plants.
They're just unsightly.
So sounds like that's
some good advice for them.
I'm gonna go, sorry.
Jason: You could use just a, you
know, a small concentration of hyper
course acid in your feet as well.
You know, that's gonna do two things
to help keep your lines clean and
sanitized and give a little bit more
dissolved oxygen to that roots that'll
help prevent any anaerobic areas in.
Seth: Substrate.
Yeah.
And to that point too, I do know
a few growers who do a very light
zero tall spray in, they're under
canopy early on after they've cleaned
it up just to keep the tables.
And it's, it's a sanitization
maintenance spray.
You're not actually ducking the
roots or putting, you're not
getting any into the root zone.
You're just doing a light
mis for sanitation reasons.
And a lot of times that's places
where they've had history of you know,
fusarium or pithia in their trays or
irrigation system, and they've just
developed some great sanitation measures
and sometimes developing that can
also help the some of those accessory
problems, like the mold and stuff.
If the rooms, if there's no mold in
the room, that also helps as well.
You know, finding that source
of, okay, is it in the bedroom?
Is it in the flower room?
Where's the mold in my facility
for these sports to come from?
. I mean, it doesn't, it doesn't
appear entirely out of nowhere.
Although sports are ubiquitous.
If we've gotta control
the environment, it is.
But if we've got a controlled
environment, we should be reducing
some of that compared to having
a trashcan full of moldy bread in
the room, you know, for instance.
Jason: Yeah.
I wonder if like a UV air purifier would,
would help in that kind of case too.
Yeah.
Seth: You know, any kind of air pur
via air sanitizer, you know, even
though I'll, you know, like you said,
those mold supports are everywhere.
They're ubiquitous to our environment.
, any effort does help.
Anytime you seal off an area and you
do start cleaning the air, you know,
getting too surgically clean in that room.
Yeah, that might be kind of hard.
But anytime we reduce
sport count it's better.
Less rates of infection.
I mean, that's even why we see for
compliance purposes and testing.
You know, we don't, we don't say,
Oh, it can have zero bacterial
fungus fungal spores in it.
No, we have a CFU count that
it's allowed to stay below.
And that's just because we know
if you go above well, we're
more likely to see problems with
bacteri and mold in the product.
Mandy: Awesome.
Thank you guys.
I'm gonna quickly cover our last question.
Jason, over on YouTube
wants to know what you see.
Do you expect to see in runoff during
week four flower compared to going in?
I'm seeing pH drop in one cult
in one cultivate, one cva.
How do you interpret a pH drop?
Staying steady or rise in runoff pH?
Jason: Usually pH imbalances come
from the nutrient composition, the
way that the plants up taking it.
So you know, if you're seeing one cult
bar in an area that the pH looks good on
runoff no drift, and then one where it's
too low, it's likely that other cultivar
is just just trying to indicate that
it has an imbalanced nutrient pull up.
Meaning that the nutrient composition of
feed is not getting eaten up in proportion
for the elements in that nutrient on
Seth: that cultivar.
. Yeah.
And I mean, you know, treating
that there's, there's a
range of things we can do.
Typically the easiest to do is to
start to up your ec in your feet
and push a little more runoff to
try to correct that imbalance.
What it is really often a sign of, again,
if it's drifting down, you're plants
feeding, It's pulling those negative
i, those cat ions outta solution.
Pushing that down, making the
solution more positive if it's going
the other way, well , why, why are
those negative ions accumulating?
Why are we going the wrong direction?
And usually we do want to see a, a
fairly static, if you know anything,
a slight drop in pH, but not much.
Mandy: Great.
Thank you guys for that.
That was all of our questions for today.
Yeah, we covered I feel
like a record amount.
I think I've said that before,
but we got through 'em all today.
Thank you guys.
Any other messages you guys wanna tell
our audience before we sign off for today?
Jason: Well, if if you're at Hall of
Flowers next week, come say hi to me.
I don't know if we'll
be doing office hours.
Maybe.
We'll we'll have a chance just to
highlight some of what's going on
down there at that, that exhibit.
And Seth can hammer out all
the knowledge on his own.
Seth: Yeah.
Hopefully we'll have some live
coverage next week, but who knows?
We gotta, Jason, Jason's
not a full news team.
We don't have a van to send for him.
So , we'll see what happens.
Who knows?
We'll have,
Jason: we'll
Seth: have planned.
Yeah, she's, she knows a little
bit more about that than we do.
There
Mandy: we go.
Who knows?
You guys are gonna have to log
in and see . With that, I'm
gonna go ahead and sign us off.
