Kittycatpenut had a typo, its Hydrofarm. I am using three of them and they work very well for the money. Here is the link:

You can also get a thermometer/hygrometer at walmart for $8. You HAVE to know your temps and your humidity. Please take a look at the ball python caresheet as well.

I would try to find something else to keep him in. Wal-Mart sells 10 gallon tanks for about $10 and that would be much easier keeping your temps and humidity in.

As far as sitting in the corner, a few of mine have done that the first day I got them, but they figured out to get inside the hide after a while, just give him time.
