Is there anybody here that uses heat panels and could tell me how they work? How do you hang them, from the side or top of cage. Do they dry out the air like bulbs? I was thinking of getting rid of my lamps and UTH if they work like they say. And how much am I looking at to heat a 36"w x 26"d x 44"h wood enclosure. Or if you have any other ideas I would appreciate them.
