cut a hole in the top and put screening around it, since heat rises this will let it escape. if you are concerned about your bulb emitting to much heat i would have a fan blowing up towards it with the holes on top. make shure you make one big hole that you can cover instead of a bunch of small ones, my bad.
santacruz_organic Reviewed by santacruz_organic on . My new lights, Opinion Needed! Alright I just went to the hardware store to pick up lights for my first one plant grow. Just a little detail, There going into a grow spot of 31" H x 16" W x 10" D I bought 3 23 watt mini soft white CFL's ( 1600 Lumens, 2700K) Will this be a problem because one, i was looking for 30 watts. and secondly, i didnt realize they were "mini soft white" i was looking for daylight. Will this be a problem for vegging? For flowering I bought 2 40 watt Soft white CFL's with 2600 Lumens and 2700 Rating: 5
