There's a lot of conflicting info out there on hognose temps. I've seen some sites that recommend a hot spot of 95, but most say around 90 (some even say lower around 86 like you'd keep a cornsnake). They don't need as much room as a BP especially the males which stay smaller.

I would say once you find a breeder you like, ask them what temps they keep their hogs at and do the same.

I would also suggest getting a more well started snake. I got a juvie that was around 12 grams last July and have had feeding issues with him, which is why I'd suggest a larger snake that is already feeding regularly on f/t or whatever you want to feed. Apparently feeding can be a common problem with hogs, so just be prepared. Other than that, he has been a neat snake temperament wise.

Here are a couple breeders that I have heard good things about.
Cahaba River
Extreme Hogs

This is the breeder I got mine from. I think their prices are a little high for normals, but they seemed honest and I didn't have any issues with doing business with them.
