Typically, if you've decided to go with both the UTH and the lamp, you should have the UTH on the cool side at a controlled lower temperature. NO LOWER THAN 75 F. Any cooler, and that is bad bad bad. But too warm is bad, as well. If you can't keep the temps on the warm side between 90-92 with just the lamp, try upsizing the bulb. Also, regarding the hides and water dish, BPs are secretive, and they should have same-size hides on BOTH sides. This way, they will not ignore their needs over security. Hope this helps, and hope any of the experts out there catch any false info I may have accidentally given you!![]()
