I haven't been able to find a definative answer on this. How long should I leave my exhaust fan off while the co2 cycle is doing its thing? I know it takes 9 minutes to fill the room to the right ppm...but how much longer should I let them sit there and soak up the co2 before I turn the exhaust back on?
