extracting co2 from mono tubs for plant use
    #19075486 - 11/02/13 02:44 PM (10 years, 2 months ago)

hello i am looking for other users who could help me find a way to transport co2 from my monos or other growing chambers to my plant grow room.

here is my initial idea

in my grow room i would have a reservoir with a pump. the pump would send water thru a hose to my mushroom room. connected to each of my monos would be a suction hose that would draw off co2 from the bottom of the tub( the area most concentrated in co2. the suction tube would be connected to a venturi valve or aspirator of some sort(haven't began sourcing any parts yet). after the venturi the water carrying the air sucked in by the venturi would make its way back to the plant grow room. and be degassed by a degassing column, stripping the water of any co2 over ambient growroom concentration. the cycle would then continue

im sure i made some mistakes in writing this but if theres anyone that could help me with my idea it would be appreciated here is a diagram of my system. i intend to have many monotubs/growing chamber

your better of with bags of myc in the room and tjetes probly mote co2 at the top of your chamber thhen then the bottom as it rides heat currents putt off by your sub

lol sorry on my phone, there are companys that sell bags of myc for such a thing and was just pointing out that the bottom doesnthave higher co2 levels as it rides up with heat currents

yeah for $30 lol. i can buy 30pounds of bottled co2 for that price.
my goals for this would be to exaust co2 from my tubs while using that "free" co2 for use in my grow room.

ive always heard that co2 settled to bottom. thats why it is suggested to pack the holes on the top loose and the holes on the bottom tight.

It doesn't. It mixes with the air.  In most fruiting chambers the CO2 is higher near the top because that's where the air exhausts.

You won't get enough from your monotubs to do your plants much good unless you have a shit ton of monotubs.  I'd suggest making up a bunch of substrate bags.  I'm using nearly 100 in my grow room, and I can keep the CO2 level above 700 ppm most of the time.  You'll want the substrate bags in a closet or other separate enclosure so you can shut off the CO2 to your plants during their dark cycle.

roger im doing a shit ton of monotubs, 75-100 at a time.. thats why i want to tap into this if i can, why pay Airgas when i can use existing resources.

i actually have a plan b if you could take a look RR. it involves using trays instead of monos

i missed something in my diagram the intake will have a nozzle that will release fine mist from a low output nozzle at 120psi. at set timer intervals

The exhaust should be on top, co2 rises.

not to quote roger rabbit, but this IS simple chemistry,

otherwise the co2 in OUR enviorment would layer and float into the upper attmosphere, on calm days. and we wouldnt breath a solution of

Nitrogen (N2) 780,840 ppm
Oxygen (O2) 209,460 ppm
Argon (Ar) 9,340 ppm
Carbon dioxide (CO2) 397 ppm
Neon (Ne) 18.18 ppm
Helium (He) 5.24 ppm
Methane (CH4) 1.79 ppm

. the only reason i had thought that it was highest at the bottom right on top of the substrate was because thats where its being released from, plus some of you stoners brainwashed me

We all know co2 mixes with air (including hacker) He was saying you should be pulling the co2 out of the top because it rises. Not because the co2 itself rises but because the warm air in the fc rises. The RR quote also states that

Yes, it mixes with the air, which is rising....there is more co2 at the top because heat and humidity both rise, pulling the co2 laden air with it.

So in this instance, co2 does rise to the top of the chamber, not because that is where the exhaust is, but because it just rises.

I believe you should stop listening to everyone on line and try it out! I have seen multiple times where a boatload of people tell someone on here that certain things won't work or simply can't be done that I already have tried and have found at least some success. That said I couldn't figure out why last year my plants were growing faster and yielding more/healthier until I looked at exactly what was different.  I realised when everything was going ape shit that I had 4-5mono's running at all times and they were just on the floor in the same room no hanging or 1000s of lbs of mycelium just a couple tubs.                                                                                                                                                                        Ever since I came to that realization I've tried to keep mycelium running at all times in the room and it helps keep the rh up and even at one point set off my gas detector in my home!

just a little update, i believe i found the perfect solution.

i decided to stick with monos, their just to easy. im misting once before the first flush. for CO2 extraction i use a telaire 8002 ventostat, i have it connected to a heavy duty relay. its controls two fans, one injecting fresh outdoor air into my grow room and another exhausts CO2 laden air into my plant grow room. i have it set to start the fans up at 2100ppm, and shut off at 1500ppm. my grow room stays at about 1350ppm, i can live with that as im only running 1000Umoles/sec/Meter2 ppfd at the canopy.

ps im running 4 gavita 1K DE lights at 1150w. 2200Umoles/second PPF baby

i agree with you i take what i read online for a grain of salt.

what kind of gas detector was that
