I'm making up plans for an enclosure for my largest ball python. I'm making it 48in long 24in wide and roughly 18in high out of wood with glass sliding front panels. My question is about heating. I want to use a 20x20 under tank pad on the warm side. What are my options? I'm thinking about a glass bottom for the entire enclosure, or maybe glass on the warm side? I think I'll probably need a ceramic lamp in addition to the warming pad. Anybody have any thoughts/advice? I know there are probably lots of threads with this same question.
