redaaron Reviewed by redaaron on . Heat, Exhaust and Co2 for new room I'm starting a new room and want to add a co2 generator. I'm starting with a space of 6'Wx12'Lx6'H. I have a perfect exhaust opening ( 6"x4") leading outside. I am starting with a 1000w switchable HID ballast with Raptor reflector that has 8" flanges (adding one more light for second grow), 8" can-fan with appropriate can-filter and c.a.p. air-3dn controller (wanted the option of a heater at night if necessary). Question is I would like to add co2 and wondering if a CGE method is good Rating: 5
