So as per the instructions from someone I know, I cranked the infrared bulb all the way on the dimmer (it is a 50W) and turned the UTH down on the herpstat to about 91. The new temps I am getting are:

91.9 F above the UTH under the substrate
89.6 F on the warmer side ground level outside the hide
78.7 F on the cooler side ground level

Are these better temps now ? At night, my temps seem to drop too, I will have to do an update later on tonight..

As for the type of enclosure.. I am using a regular 20 gal glass tank with coco husk plantation soil substrate, two identical hides on each side, water bowl in the middle, screen top with a big book cover half of it, infrared heat lamp w/ dimmer on the warm side.

Humidity has been around 60% all week, only today is it floating around 50%.
