I just made a switch from two 20w fluro to one 400w Metal Hallide w/ reflector in my apartment closet. After the first day I noticed my babies were burning with temperature around 95 F. I don't have a fan blowing and I'm looking to add one to the system. Will the fan actually decrease the temperature or will it only create wind? Should I rely on ventilation to fix my high temperature problem, or are there other methods?
