No tribble a tall, aye lad.Thanks Ghostwolf! Mean mr.mustard said that using two ballasts (two lower watt bulbs to achieve the same watts as one larger watt bulb) would actually produce more heat than using the single bulb. So, I decided to go the route of the single bulb. I may also consider installing a small computer fan (I think I've got one laying around somewhere... just have to find it!) to vent it like you said. Again, thanks for the input!!
