With a terrarium setup I have found it works really well if all heat sources are on one side of the tank. With this example, the heat lamp and UTH are both on one the same side. This seems to help create a perfect basking spot from both the top and bottom and the heat from the lamp on warm side, creates the perfect ambient temp on the cool side. I also find having the heat lamp on the same side as the UTH doesn't seem to kill my humidity as much. This is based off information I found on a boa care sheet from redtailboas.com, I don't see why it would not work for ball pythons. This may not work for everyone one but seems to be worth an attempt especially with glass setups.
