Woah, Thank you so much Craigafrechette!
I didn't even know about PVC enclosures, so it seems that I have a lot more research to do.. This also sounds like it would be a great idea for ball pythons? Is there a reason that PVC is cleaner than glass? Or easier to clean?

For the reptibark/ecoearth cocofiber mix, is that one to one? How humid is "too humid" for corn snakes?

I'll look into a thermostat for sure! Are there any reliable brands/sources that I can find?
I will definitely do more research on these as well.

Seems I've only begun to scratch the surface!
