You are not far from solving the problems of humidity. Get an undertank heater about 1/3 the size of the tank, and a thermostat, set the thermostat till it reads 88 under the warm hide, then put spagnum moss in the warm hide. This will solve the problem. If its still a problem zoomed makes a reptifogger that works really well. I use one cause it gets really dry here on long island in the winter. I put my fogger on a timer to go off every 6 hours, and have never had a bad shed yet, and my guy is over a yearold.
