I obtain an acu-rite humidity gauge from Home Depot. It's in the middle of my Pyxie's tank just above the substrate floor. More than half of the tank's top is covered with plastic wrap and there's a towel over that. The gauge reads only 62% at the moment, but since I just heavily misted the substrate and walls I'm not sure if that's right. And if it is, how I can raise the humidity to 80% as is preferred by Pyxies?

Temperatures in the mid 80s by day, mid 70s by night, via infrared and night-glo bulbs. Never had the desired results with heat mats/cable.

I've had my frog (got as an adult) for nearly a few years and have never resorted to any fogging or other such devices before and she's apparently done well without them.
