You want the UTH about 90-92* max. If his hide is right over top the UTH, I'd move it over to one side, so all the heat rising from the UTH isn't just
over-heating the hide. Snakes typically choose to hide over being the right temperature, if & when they can't do both at the same time...so when the
hide is too hot, he won't realize until he is injured. You want to offer snakes at least 2 hides, one without heat and one with heat (regulated so it's not
too hot) so they can always hide at the right temperatures. It's obvious that you care about this snake & you're doing the best you can under the circum-
stances (being unprepared), so I'm glad you found your way here where we are happy to help you sort all this out.
