There is still no animal in the enclosure. I already know unregulated it will produce a max temp of 120º inside the enclosure. That is hot enough to be seriously concerning to me. whispersinmyhead that is a really great idea. I have never liked having a probe located where a snake could get between the probe and the heat source and stay there. Yours is an elegant solution. This is my solution... set up much the way it would be for arboreal. I have not found it to deliver stable temps they vary a lot not cooler than I'd want but sometimes much warmer.

It is an interesting experiment but I am not totally happy with it to date. Perhaps I will try the floor mounted elbow next.
Rich what is the accuracy of the VE probe? why is it not stated anywhere?
