That depends on air movement. If you have fans blowing then its going everywhere no matter what. If it has zero air movement then i suppose your theory would work just fine assuming your releasing it under all the plants equally. Either way , i would have the sensor right below the canopy.
Ah right yea that makes sense, I got like 3 oscillating fans pointing down at the canopy
A can of expansion foam works great
Well my set up is a room in a room. I built a timber frame with white panda film stapled to to it on the inside of the grow area, so the timber frame is visible from the outside, then a zip up door for entry. I’ve caulked the ceiling timber and the timbers that meet the wall either end. Then I’ve duct taped the fuck out of it too haha I’m hoping it’s ok. I’ve had to build my portable ac into the wall so the rear end where the intake is doesn’t suck all my co2 out haha SO much fuckimg around but hopefully wil be worth it
its time for me to add co2 myself but im too lazy. Thats a LOT of shit. intake, ac intake, outake/s. The outake is going to steal all my co2 so i would have to stop all movement for x amount of time , then turn it all back on..... fuck that seems like a lot.
You could just get a regular window AC
hes right and im pretty sure the portable units are the same. its gets its air from inside the room. The one going out is just for heat to go out.
Yeah I can't imagine how you could hook up a single hose portable unit so it doesn't suck out CO2, but it sounds like the OP rigged somthing up that might work
My portable works so wel I’m so happy with it. I had it in the room at first with the exhaust hose coming through my panda film and up through the ceiling into the loft but then I realised it will juts suck all my co2 in so had to reset it all. Literally cut a rectangle in the panda film, have the front of the unit where the cold air comes inside the grow room and the rear of it where the intake and and exhaust is out of the grow room so basically it’s half in half out, then I’ve juts duct taped the panda film round the whole unit and I’m hoping that should be air tight enough lol! Proper DIY job but fuckkkk it
Just built it into the wall so the intake and exhaust (both on back of unit) are out the grow area and the cold air outlet is inside the room. The seal the panda film to the unit
Yea you can’t really run outake fan it will just cost loads of money in co2. Need ac to control the environment, I’m new to it myself but inthink
im running lights on during the day atm and the environment is spot on atm, but that’s probably because It’s winter and the day time temps don’t get above 10 degrees where I am right now. When the summer comes i probably will switch to light on at night like you say
Well your portable AC has to pull the cold air from somewhere also, so it will be pushing non co2 enriched air into your room, right?
Yea I guess that will be the case but that will be fine won’t it? As long as the co2 I’m adding doesn’t get sucked out, I guess it will be regular air pumped in through the ac mixed with pure co2 that I’m adding
Yes that is true. but im thinking if you had your intake inside your room then it will just recycle your co2. the ONLY thing that gets vented and "wasted" is heat. The intake will just suck up your co2 and toss it right back into the room, mixed with cold air.
