i always hear heat issues about 5 + 20-40w cfl's. but what about 1x 250w cfl? in a 0.6mx0.6mx1.2m tent, with a desk fan aimed at top of plants, and a few computer fans for vent. air intake is there of course. any idea's?
jay2431 Reviewed by jay2431 on . CFL heat question Hi all. I'm working out the details for a rubbermaid grow setup that is going to be 7.39 sq. feet. It's going to have 2 passive intake holes about 1 1/2 inches wide on one side, and 2 computer fans hooked up on the other side for active exhaust. I want to put 8 40 watt CFL's in it for a total of 21200 lumens. My question is, am I going to have a major heat problem with this much lighting and this small of an exhaust? I don't want it to get over 85 degrees and I would prefer not to burn Rating: 5
