Check this out http://www.ball-pythons.net/forums/s...ight=tub+setup

It gives some pretty good pics and info about tub setup. It's not perfect, but should help.

As far as thermometers and humidity gages go -- most people on here agree that if it's not an accurite it is garbage. You can pick one up at WalMart for about 12 bucks.

Good luck!!
