So despite my powerful google-fu I can't find all that much information on sealed grow rooms beyond the basics: CO2 is added and monitored and the plants soak it in expelling all the oxygen needed for the grow with climate control being taken care of within the room. No air in, no air out, just CO2 in. Beyond that there's really little practical information that I can find. What I mostly want to make sure I get right is the whole oxygen thing... As I'm in the market for an air conditioner and CO2 supplementation system I might as well go the whole 9 and seal things off so that no CO2 goes to waste.
As it is I built the room by sealing a framework in with panda paper and gorilla tape, so It's basically a giant balloon with a garden in it. I've sectioned off and light sealed a quarter of the area for vegging and threw together 4 flowering 'modules' (4x4's lit by 1000w HPS in Adjust-A-Wings, either E&F or drips). At the moment two 740 CFM valu blowers ducted to 10"x40" carbon filters suck air out and a single 400 CFM valu blower pushes it in. A dehumidifier I bought at Sears keeps RH around 40% but with 3 lights on I'm going over 85 degrees any night the temperature outside floats above 55, So I'm going to add an AC. My house already runs on LP, so a gen is the obvious choice for CO2, especially since my garden ultimately fills a 16x9 area roundabouts and I feel like that's pretty big to be running a tank system.
So all that said; how does one calculate their gardens "respiration?" How much CO2 will a given area of canopy consume, giving off how much oxygen? I don't wanna get everything set up and then suffocate the first time I go in to fiddle with the ph! It can't be as simple as throwing an AC and gen in there and just sealing it shut. I'd also like to know if I can actually push the CO2 up beyond 5000ppm with a gen like growers will with tank systems to kill off pest invasions. I'd really love to suffocate all the spider mites that have been keeping me in my grow room on squish patrol.
I have loads of questions on the construction and maintenance of sealed grow ops so even if you just point me in the direction of some good resources that would be awesome; thanks everybody for your time!
