Can anyone recommend a good C02 system for a 8 X 8 X 8ft grow room? I tried the Exhale bags and they seemed to make a difference but I would like to step it up a notch. We had a couple of hot days up here in the 90s and with the LEDS on full 100% they temps stayed under 90 but if I can add C02 and leave the AC off. It would be great.
I wonder what would happen if I mixed C02 into the air pump for the RDWC? Is that a totally stupid idea?
