Ok, so I taped black foam board around 3 sides of the tank, leaving one of the long sides uncovered so you can see in. I kept the carpet, but moved the heating pad to the bottom of the tank (it included little plastic feet to put on the bottom of the tank for airflow, too). I also doctored the screen top so that most of it is covered in tin foil and duct tape, but left a strip of screen about 2 in or so in the middle uncovered for ventilation. I also put a little of the damp sphagnum moss under each hide. The heat got up to 92 on the warm side and about 82 on the cooler. However, the humidity still wouldn't get up high enough, so I put a layer of aspen bedding down over the carpet and put the sphagnum moss on top of it under the hides. The rheostat is on its highest setting, but the warm side of the tank is sitting at 85 and the cool side at 78. The humidity is still only around 52. I'm misting more often than I think is healthy for my little girl. I'm running out of ideas here. I might try taking the carpet out and just trying the bedding and moss to see if that allows more heat into the tank to evaporate the water from the bedding and moss and get the heat back up as well. What do you guys think?
