That's a great idea! And it gets me thinking. Maybe I could get a hatchling hog, and keep him/her in a tub placed inside the divided T8. I could use the RHP to create the ambient temp needed and then use a UTH under the tub, again inside the T8, to create the hot spot. I plan on getting a Herpstat 6 so I'll have a few channels spare. It'll take a bit of experimentation to get the set up and temps right, but it should be doable.
Thanks for the suggestion!
