I do have a bit more questions, if that's alright.

1.) What's the best way to heat the tank from the bottom? I've heard of people using UTHs and Tape/Wire. What would be the way to go (Brands/types)?

2.) I've heard snakes don't mature until they are 3-5, is this true?

3.) If I get a juvenile, what would be the expected time of when I have to upgrade the habitat size? Is starting with a 10 gal. ok?

4.) I live in a high humidity state (73%-100%, loads of rain and not so nice weather), would that make my snake more vulnerable to scale rot and such? How would I go about lowering it? I know to use items that do not raise or hold onto the humidity.

5.) I was told that a 36-inch by 18-inch by 12-inch was suitable for adults. When I do upgrade, would it be okay if the width was off by 6 inches, or would that just make it harder to put hides in?
