Thanks for the tip, the 50cfm fan is not even making a noticable difference with the temp. Anyways, I got to run out the door, but later today, I should get a chance to get the fan.

A couple of the plant are drooping really bad. Maybe I should take a couple pics in normal light once I get back so you guys can see better. I think I may still be overwatering, but I waited until the first 2 in. of soil felt dry, but after I watered last, it seems like they drooped a bit more and one hasn't really grown since.

And the bulb is correct, 400w, ballast is 400w. I read more on this though, I guess its not the ballast that needs to cool down, but the bulb...it makes sense, if you look after you turn off the light, you can see it glowing, I guess you know its ready when the bulb stops glowing. The bulb and ballast seem to be working just fine now.
