Scottychaos: I have no idea why I got another heater. I guess cause I'm an idiot and thought it would solve the problem, lol. I am using two 120V 15W incandescent bulbs. The light is built into the hood so I can't move them higher. I have them on all day, from 7am-8pm. Nope I don't have real plants. I just took out one of the bulbs, so I'll see if that helps, it should though. I'll go get some fluorescent bulbs this weekend. I just didn't think 2 15W bulbs would do this!
