So I guess my question is what are my options for heating my enclosures?
Oh man, this is sounding like a broken record... but here goes:
It all depends on WHAT ANIMAL you are trying to house. Not all reptiles were created equal. Actually, they weren't created at all. They've evolved for millions of years to exploit specific niches. If you want to have us tell you how to create that niche, then tell us the animal you are trying to house.
