I currently have my BP (about 3 months old) in a ten gallon glass tank. I have two identical hides in it (one over the UTH and one on the cool end), a large water bowl, and some fake plants. Besides the UTH, I use an infrared bulb to heat the tank (93 on the hot side, about 85 on the cool end). I've been using Desert Snow as the substrate but decided to switch to cypress because of the low humidity levels in the tank. I'm also using some sphagnum moss. Despite using both the moss and cypress, the humidity levels consistently drop to 40%. I have to mist the tank multiple times a day just to keep it around 50%. I have half of the screen top covered with aluminum foil; should I cover more of it? I'm really at a loss here and don't know what to do. Using a plastic sweater box isn't really an option because the air temp in my house is 70 degrees and will be 68 degrees all winter. How would a UTH be able to raise the air temp enough in a sweater box? What measures should I take to help raise the humidity levels? I'm afraid my BP is going to suffer because of the low levels. Any suggestions/help would be greatly appreciated. Thanks.
