Remember no CO2 in people living area's. If your room is in your house be very careful. Co2 can displace o2 and fill a house with enough to kill everything that breaths. It is heavier than air and will suffacate.

With that said. You have 1080 cubic feet or 360 cubic yards. Lucky PigLet. Your regulator will tell you how much you release into the room but a meter to go with that would do all the work. You would flood the room to 1500 ppm's and raise temps to 85 degrees. Make sure your rez water stays at 70 degrees. You need a big HPS light too. After about 4 hours flush the room with fresh air and then flood with co2 again. flush with fresh air again and then you don't need it during the dark cycle just fresh air.

Or if you just want extra. Run a hose from the regulator to above your plants and when the lights are on give them a slow leak of co2. fans help move it around good. Be careful I have seen some that waste a whole tank in one night cause they leaked to much.

You really need the meter control to go with it. That way you won't waste it.
