yeah i use aspen bedding, and a large water bowl under the heat tank, as well as a uth underneath her hiding log. still was a pain to keep up. so tonight i tried using tin foil on the long side, and on the side thats up against the wall. im hoping that would help keep the heat in, and not need the heat lamp on as high, and ill see if that helps the humidity a little. i would go with a plastic tub, but i like seeing it.
