I first would like to thank everyone who has helped me with my questions up to this point. Its very much appreciated. The only thing I have learned on this sight but haven't applied yet is co2. Please school me if I'm wrong but heres my take on it. I have a 4 by 2 small tent with a carbon filter inside that creates negative pressure. So much so that the walls suck in. I think that's a good thing for odor control and fresh air being replaced rapidly. So my point is if I put a co2 tank in the tent, won't the filter suck it out so fast that its not really doing much good. I don't want to waste my money by having my basement full of co2 and not my tent. Am I right about this?
