I am setting up a grow cabinet made out of two identical storage cabinets. One will be for vegetative/cloning and the other for flowering. I am running a 400 MH in the vegetative and a 400 HPS in the flowering. Both lights will be vented separately. The grow areas will be roughly 4'x3'x2'. I need to know how much ventilation will be needed, where the venting should be located, and what kind of fans would be best. I'm thinking either 8" duct booster fans, which I'm not sure would be strong enough, or maybe squirrel fans which I think might be too loud. Any input is helpful and appreciated. Any pics of someones similar setup also very helpful.
I got a 6x6x9 ft grow room and I use a 256 CFM Bathroom fan and it pulls warm air out real well. I only got a 400 hps in there though. I put this in the grow room design setup section.
