I'm still playing around with it. My understanding is that it doesn't really matter what temp the thermostat says on the hot side? As long as it's getting to 88-90 inside the enclosure? When I put the setting to 90 it was not nearly as hot as it should be in the enclosure, so right now its set to 105, I will check what it is at when I get home. I ended up cutting a small hole in the screen to get the probe in there and it seems to be working for the cool side. I'm still keeping an eye on the temps on the cool side because last night it was 64 in my room because it was so cold outside. I'll work on something to get the sides covered.
I have been looking at the T8 from Animal Plastics and I emailed them with some questions. Would this be big enough to last him for his entire life? So for the T8 I would use a heat panel on the side and a UTH?
