I have a question concerning CO2. If one had a sealed room that was about 158 cubic feet, how much CO2 would one have to use to keep the gas at 1500ppm? I used the calculator-link on the sticky in one of the other forums, and according to that a 20# bottle would last about 7.24 days in a 158 cubic foot space. Somehow this doesn't seem correct. I was wondering what some other folks might think. In this situation, about how long would a 20# bottle last if one were using the "sealed room" approach, as opposed to just using CO2 to "boost" the atmosphere periodically during the light cycle in a non-sealed room? Thanks, in advance, for the input!
