Thanks for the quick replies! I suppose it is very possible the hygrometer isn't working. It also reads temperature and that usually matches up with my gun, thermostat, and another thermometer, but I will have to pick up another and see if I get a different reading. I did think it was odd how hard it was to maintain in a tub. I'll also look into a different substrate, I have been using paper since its easy to clean, reduces any ingestion risk, and I work for a newspaper so it is readily available lol. However, if mulch or reptichip would be better I'll look into it.
