Since hind sight is 20/20 and I didn't find this forum until after it was built, I now know it's much too tall and a bit long for a BP's needs, but I went with it anyway. I've been able to maintain a hot side of 92 and a cool side of 82 with ease. Humidity is a little low at 40% but if I mist it goes up, so I'll have to keep up on that.

On the left side is a moist hide with sphagnum moss. I put a rock on top to keep her from knocking the lid off, and we found the plants at a craft store. The water pan is a small kitty litter tray. Behind the water pan is a tree we had in her old tank, and then to the right is her stone hide we moved over.

I put in an indoor outdoor thermometer/hygrometer, you can see it on the left side mounted low on the wall, and fed the probe over to the hot side, where it pokes out from under that rock right in front of the hide.

2 heat lamps, a 250 on the cool side that is barely turned on, and a 150 on the right side that is about 3/4 the way up on the dimmer. I had the 250 on the right side, but it seemed to have less even coverage, like there was a cooler spot in the center, so I decided to use that on the cool side. I'll probably get another 100 or 150 bulb for that. I tried a 75 earlier today and it didn't keep it warm enough. Both of the bulbs are wired to separate dimmers, which are mounted in a switch box on top of the cage. I also have a vent like you'd use on a heat duct on top, that can be opened and closed to help regulate things. The entire top part is hinged and opens up for access to the bulbs, and the window in front is hinged at the bottom, to allow for easy cleaning and access to the cage floor. The whole cage is about 4' long, about 21" deep, and the window is 24" tall including the frame around it. The light box is 6" tall.

When we put her in, she explored all over, took a soak in the nice warm water, and then retired to her hide on the right side of the cage.
