Thanks for the continued replies, everyone! I picked up a Zilla thermohydrometer and have her in the bin in the hottest room in the house. The meter is telling me temp under the substrate is F 74° and opposite just above the waterbowl is saying 51% humidity. This may not be ideal, but it is already a HUGE improvement from what she was in before. I do have the UTH attached, but I do not want to power it without the proper temperature controller. I am definitely going to check through all the links everyone has provided and see what I think of them.

I understand this, but it will most likely not be a problem for me. The dish I use is an Exo Terra large size. It is nearly impossible to tip over, and is buried slightly in the aspen. I will keep this in mind with my future purchases, though.
