Wow. Im shocked at how few people here havent even heard of a "perfect" sealed room. In my opinion it is a necessity if growin over 2000 watts in flower alone. By itself will add 1/3 more bud to your harvest. I am running a 4000watt sealed room w/co2 injection which i must say isnt that expensive. It is the original set up that is costly. I have 3 20lb tanks and for me i can ussually make in a 6ft wide by 20ft long & 6ft high can make it 1 tank last about 6 weeks so approximately 30dollars to have your yield enhanced by a third is less than your electric bill for thos 6 weeks. I thik co2 burners are the way to go in a large opp./ for me co2 injection has worked wonders took me from max 5-6lbs to easy an ten pounds. Which allows me to go for quality over quantity as well as having complete control over the room. If you are not growing this way you should seriously consider it. Peace, M3
