i have a grow room set up in my closet with 9 plants and right now cfls. heat has been a problem in my room for a while and when i go into flowering im going to use a 400w hps so i imagine that the heat will go up even more so i was planning on using co2. but i didnt want to buy one of those crazy co2 systems or whatever so i was thinking couldnt i just use a 20oz paintball co2 tank with a release knob on the end of it and leave it in the room for a while. would this work?
