i think you may have misunderstood what i said. Their is no window, i am just recirculating the air in the room, hence why i want to use co2. I'm just wondering if co2 will move through the tents or just lay on the floor. Thats what i'm asking really; will the co2 in the room be moved around by my setup or will it just sit on the floor not doing anything.
Sigur Ros Reviewed by Sigur Ros on . Co2 Question Okay basically i have a questions that hopefully someone can answer. I am running 2 grow tents in a sealed room with aircooled hoods that are hooked up like this: carbon filter --- > hood --- > fan --- > the air is exhausted out through the top of the tent back into the room. The fans are 530 m3/h (one per tent). I am not using an intake fan, its passive. Rating: 5
