whas up, i just got some excellofizz, to produce co2 in my tiny ass grow area 2'x3'x5' and i was just thinking.....if that area (air tight) is full of co2, then won't the pump that pumps air into the airstone in my resovoir just pump co2 into the water instead of oxygen....you know for the roots? I don't see any air inlet on the pump, but the air has to come from somewhere right? can anybody tell me what to do?
as long as your grow room/cab has good airflow, by this i mean are there at least one fan inside circulating air? if air is constantly moving, it's all good. the plants breathe c02, and expel o2. the roots need o2. you'll be fine.
