You asked how I had the Sterilite containers set up, so here's a photo:



As you can see, each one has its own individual digital indoor-outdoor thermometer/hygrometer. Each also has a heat source underneath, two hides, newspaper substrate, and a water dish. Seymour lives up top and mostly stays under the rock in the back middle. Hanover lives in the first drawer and mostly stays in the pvc hide on the left or on the left under the paper (when I found he was doing that, I put a pad under the paper to keep him from getting burned and he stays on top of or to the side of it). Snyder lives in the bottom drawer and mostly stays in her little tree. The easiest way to keep both temps and humidity right so far has been to use the 49 qt. drawers with a human heat pad with adjustable heat.
