So I've added a thermostat to my uth and made the warm end more "hidey" by covering the structure with plants. The floor temp is a stable 90F. I picked up a ceramic heat emitter and have that on a dimmer as well. I've placed the fixture over the Center/right of the enclosure and covered the screen on the top with space left for ventilation. Cool side is now regulated to 75 overnight and 83 through the day.
Humidity is between 45 and 60%.

Fingers are crossed. I usually attempt to feed on Weds evenings. Here's hoping. Thanks fellas! I really appreciate the help.
