I'm planning to buy an air cooled reflector for my 400 watt HPS and considering getting a Metal Halide conversion bulb as well. The thing is the ballast gets real hot and I'm afraid to leave it on when I'm not home. I already have a bunch of fluorescents totaling about 20,000 lumens. Can I keep the fluorescents on all the time and use the metal halide for only 12 hours a day? Would that mess with the plants at all?
