Hey, I did read the help guides and stuff on these things..but I have a few questions..

Enclosures:

Is it really better to have a small one vs a large glass one? Because everytime I see the small plastics I think "is that snake really getting the most out of it's life?"
So I'd just like to know, is it better to have it smaller or larger? Because my BP has a 30 gal glass tank with lots of things in it. (log, 3 water dishes, cave, and driftwood)

I read that some like to explore, while other people say they like being someplace small. Mine likes to climb the walls of my tank. So was just wondering..does it depend on how the snake started off or no?

I do like the idea of using plactic containers for caves and water dishes and stuff like that. But not for housing..but then again, I'm kind of against keeping any animal in too tight of a living arrangment. XD


Heating:

I have been to pet stores all over my area and can't find a digital thermostate. And I think I need one, right? I have four readers, the regular ones? For both sides of my tank so I can tell how hot the warm side/cool side is. But the warm side isn't getting over 85 degrees. I have a 20 gal heating mat on that side and a 30 gal heat emitter too. Humidity is pretty fine though. It's sitting at 70% most days. I don't let it get under 60%, I mist it when it needs it.

But I looked and couldn't find why it wouldn't get very hot in my cage. =/
It's hot where I live and we have the ceiling fan on all day long in the summer so I have the enclosure covered with a towel to lock heat/humidity in.

Any advice on how to keep it warmer, or where I might find a digital thermostate that I can stick to the base of the tank will be greatly appreciated!

(p.s. if this is posted in wrong area or anything. I'm sorry! ><)
