Thank you! The UTH is on it's way via snail-mail... It's cypress mulch and eco-earth? mixed. I also have a RepitFogger that keeps it at 99%. I'm going to put it on a timer so that it is not running 24/7. Also, both hides have moist sphagnum moss in them. I will figure out how to cover the top once my UTH arrives and I can ditch the lamps. Do you think the fogger/timer is a good idea? Thanks again!
