If you are worried about the temperature in your enclosure getting too cold on the 'cool' side, you could always have 2 uth's (or however you are heating the enclosure) hooked up to a thermostat that allows multiple inputs. For example, on the 'hot' side you could put it between 88-91, and the 'cool' side at ~80. I looked it up because I live in Canada and it gets pretty cold here, especially in my apartment. I hope it helps. Also, there are tons of posts on here detailing pro's and con's of different enclosures and how to keep them as well as 'thrifty' options. I hope I could help and welcome to BP.net. I hope you are able to add a BP to your family as they are wonderful pets
