I'm looking to build custom wood enclosures for my ball pythons. I've done a lot of reading on this forum and others, and I'm getting a bit confused. Is it better to use a heater such as an Intellitemp mat or a CHE for a wood enclosure? I would like to build 2 identical enclosures, and I wanted to make them stackable, but I realized there are lots of problems with the stackable idea. If I used the intellitemp mats, I think the stacking would work easier, but I'm not sure they're the best option. Please advise!
