Well, at $5.70 a gallon, you must have a pretty good idea that this will work. For 100 plants and 96 btls on the wall. Will be anxious to watch your grow. I doubt the C02 would hurt the plants, since they synthesize C02 and give us cleaner air! Grow a ton of 'um outside and they will not die in the C02. The more trees and plants the cleaner the air! Wonder, if they work harder for photosynthesis if that makes them stronger bud. . .and counting 96 btls and filling um up! pr
