help with martha tek FAE

i’ve grow martha before but read that i might not be getting good enough FAE. i have a fan on a timer that cycles multiple times per day and an aquarium pump. is this good enough? i’ve had success before just wondering if it’s limiting me

Going to be hard to say without a CO2 sensor. Better to give too much FAE vs. not enough. If you don't have a CO2 meter, you'll want to just eyeball your grows and figure out if they need more FAE.
CO2 will build up pretty quickly in an enclosed area.
Personally, I think CO2 is probably the only thing really worth monitoring closely, and I may or may not have gone full nerd mode and built my own CO2 sensor system from scratch, programmed an IoT device to control vent fan speed (the 11% you see when it's on there is basically turning super slow... can't even feel any air coming off it).

...that's what I may or may not have done...
My real point is look at the CO2 buildup when the fan isn't running (it kicks on at super slow speed at 1500 ppm and turns off at 1200 ppm).

hey, growtech - you got any more info on that thing you may or may not have put together? I'm sure I'm not the only one who may or may not want to do something similar

Not sure what info there is really... it's a bunch of sensors/hardware soldered together... has a little 1" OLED screen that outputs CO2, humidity, temperature and atmospheric pressure from the sensors. Has a mechanism for calibrating CO2 levels (you basically take it outside and it will calibrate itself to what outside air should be (400 ppm). Then a bunch of code to run it (even down to building a driver for the OLED screen). Honestly it's probably outside the scope of this website. Not sure I have the patience to teach people how to source sensors and stuff from various places, how to solder them together, doing voltage regulation, how to code in C++, how to compile that code, how to get it on an IoT device, etc.
Maybe everyone here is secretly electrical and software engineers, but it's not a beginner type project to throw together if you have no background, and not sure I have the patience for it right now. Probably easier to just get something off the shelf like so: https://www.co2meter.com/products/co2-controller-for-mushroom-growers
That doesn't work for me because I wanted something a little more granular than all on/all off (I just need a tiny bit of airflow that varies based on the CO2 level)... and I wanted to make charts and nerd stuff like that. If you just need an A/C plug to kick on/off based on CO2 (like any old dummy fan), that should work.

yeah no I get you for sure - I can go looking for parts and such, I was just curious if you had any documentation or whatever you could share as a head start. The only part I'm less familiar with is the coding but I know some folks who can help with that. not interested in dropping $250 on a premade one though.

I'll see... I literally put it to use 3 days ago, so probably will have some bugs/features to tweak here and there. Give me a little time to see what works/what doesn't and I'll see about doing some documentation. Right now it was just me winging it so didn't really do any documentation or anything along those lines.

word! no hurry, it's super cool that you did it at all, glad I'm not the only one who is neurotic nerdy enough to want to know those numbers
as for OP - someone here has a "dialing in your martha" tek but I'm struggling to find it. it basically involves sitting and watching and timing when the humidifier kicks on and brings the humidity to your max setting, and again when it drops 20% or so, and adding small slits to increase the FAE until it rises and falls over about a 15-20 minute cycle. don't quote me on that number though, as I said I can't find the exact tek, but maybe someone here knows the one I'm talking about. maybe that's what you're already doing though.
It's also going to depend on what kind of mushrooms you're interested in growing - there are quite a few different teks out there, some for pans, some for cubes, some for gourmets. when I first set mine up for gourmets I didn't realize I was following one for cubes and choked out my oysters pretty bad. they're good now though.

In what fucking world do you need a CO2 meter? The amount of CO2 produced is so minimum in any growing environment.... This just seems like a lazy excuse for why your mushrooms aren't doing good. Or an easy excuse why your mushrooms are the best.

say, a world where you're interested in knowing that kind of thing on a more granular level. It's totally an art, but there's a science to it too that many people are curious about.

There is very little you *need*. You also don’t need petri dishes, agar, aseptic procedure, etc. Everything is a tool to make things easier. For me, I don’t use a thermometer or humidity sensor (no need). However, if I left my grow without airflow for a couple hours, CO2 would be up around 10,000 ppm and stuff will stall. It’s whatever you need for your setup. I’m also lazy... I’m not into fanning manually, I’m also not into over fanning (which you can’t due if you just care about CO2, but I’m also lazy with misting). Minimum fresh air to flush CO2 out = no misting or fanning ever required. For me the CO2 thing is simple and easy and allows me to be lazy.

OK what is the number 1 pinning trigger? I can tell you it isn't CO2 removal.

Arguably... Although no one ever said anything about using it as a pinning trigger, so not even sure who you are talking to there. Again, for *me* (and I'm not suggesting anyone do anything that works for me) is it has to do with me being lazy. Now I can leave for a week without fanning or misting or just not pay attention to them.
But ya, I'd guess there are some that might say CO2 levels are actually a pretty important pinning factor... as a bonus, the very low airflow also creates evaporation without drying. but again, no one brought it up except you, so I'll let you have that convo with whoever wants to have it.

We were talking about what someone should do with an enclosed grow area (a martha) and if they should give it fresh air or not.

Oh thats right, you invented a machine to track CO2 levels in the air. I thought, Hmm thats a dumb idea, why not just run a fan and cool mist humidifier. You stated that your design was too advanced and complicated to share with us. I was like, ok cool bro cause you don't need that thing you designed because I am not concerned with the level of CO2 in the air because the mycelium do not produce that much CO2 In my opinion, or at least enough to off-set the oxygen levels. And then I thought, why would you build a Martha that is sealed.... Thats also dumb because we fruit in open air. The only purpose of a martha is to help maintain humidity levels and we can run a fan for FAE which creates evaporation, and as the moisture levels change on the surface of your substrate you will triggering pinning.
But here is where I forgot what we were talking about, when you said "Arguably... Although no one ever said anything about using it as a pinning trigger, so not even sure who you are talking to there. Again, for *me* (and I'm not suggesting anyone do anything that works for me) is it has to do with me being lazy." Because I think that being Lazy is cool, but giving bad advise is equal to the asshole at the front of the plane trying to tell the pilot how to land next time.

Yep, agree with most of it. Although the point of showing the chart was to show how much CO2 mycelium actually does produce. The second the fan turns off, CO2 starts to spike way up. If you think mycelium doesn’t produce much CO2, you are mistaken. The underlying reason you do FAE is to get rid of the CO2 build up at the most fundamental level.
And correct, not trying to teach an electrical engineering or coding class here, so not high up on my priority list to teach someone how to build something similar when you can just buy something off the shelf (I didn’t invent it).

Clearly not growing oysters there huh? CO2 certainly is a factor that can indeed be measured/monitored to tweak conditions, and certainly is a factor in the quality of your output. . .

co2 is not your enemy and the fact is a fruiting sub doesn't make a lot of it, that happens during colonizing. the only thing you need to measure in a Martha is rh, can't have too much fae but you can have to little but it's an easy judgement call
