I have a tub for my ball python, and the ground temp on the hot side is 92 degrees and the cold side is 82-84. The problem that I'm having is that the ambient air temp is only around 68-69, and my parents won't let me turn on the house heater to 80 because it costs so much money: they don't seem to be very happy about getting a space heater either. So, should I just switch all my stuff to a glass tank and get a ceramic heat emitter in order to raise the ambient temperature, or is there a way to use a CHE with a tub? I know that a CHE will make keeping a good humidity level much harder, but I can't really think of another option. Any bit of advice would be very helpful, and if any of you have any other ideas please send them my way. Thanks!
