Currently running 6 23watt CFLs for veg with only a cracked open cab door and a processor fan for circulation (no powered exhaust or intake) - temps stay a pretty consistent 74-77F. That's why I thought maybe with a 50 CFM I could get away with the 12 30watters, but RoughRider makes a good point. I'd still really like to run the 12 30watters but maybe I'm getting a little greedy for lumens? Just really want a decent sized, good quality crop.
DasPachy Reviewed by DasPachy on . Amount of light vs. heat generated Growing in 2ft x 1ft footprint, 3ft vertical space (6sq ft). Want to run 12 30watt CFLs. Temps between 72 and 78F currently running 6 23watt CFLs. I know CFLs do not create much heat, but that many is bound to create some. Anyone have any guesses as to how much? Options are 50 or 70CFM fans. Think 50CFM would be enough to suck out a lot of the heat? Rating: 5
