Thanks everybody! I knew I'd get tons of good help here. Ok, so I'm testing the temps using a infrared heat gun (one of the types with a laser) The UTH is an 8x6 Zoo Med Repti Therm. It says it's 8watts....should I get the next size up which is 8x12 and 16watts? I will fit under this tank, but I need a bigger tank anyway. So I assume without a thermostat, it's cranked at full power all the time, right? I'll get a thermostat for it! So the thermostat probe would lay right over the pad in the tank, right? I would set that to 90F? How do I know if the larger UTH can get there? Maybe I should put the smaller pad under the right side since it only does like 72-3?

The bulb is 100watts and red.

She barely fits in the plastic hide I have, but if she fits one way or the other, she's fine with it, right? I have two of them so I'll def put them both in. Oddly, I used to have two in there, and she never went into the one on the left over the heat pad, but it seems like it's only 75. Maybe it's WAY hotter inside the hide and especially once she's in there?? Thus the need for a thermostat huh.
