OK, so I have been using a set-up where I had the UTH & a red lamp on the warm side for heating purposes. I had two humidity mats in the tank, one on the cool side & one in the middle, a water bowl, a hide in the middle & a hide on the warm side. With this set-up, i was able to keep the warm side between 88 & 94. After i hung out with Hissy today, I made a few changes. The changes made were mostly for the sake of humidity. I put the heating arrangements back the same as they were before. All of a sudden, about 45 minutes after i put her back the tank, the warm side was almost 100 degrees!!! Mind you the temps out here have done nothing but drop a little bit over the last few days so this did not happen because it got warm out or anything!!! Immediately i took the lite down & I turned my rheo-stat down a bit. All day long now since then, my temps have stayed at the 93-95 mark on the warm side with ONLY the UTH!! How in the hell could this have happened?? Why, all of a sudden, is the UTH plenty of heat!!?? Does this make any sense to anyone!!??
