Sorry, not the thermometer, the thing that reads the humidity.
I just used aspen, that bedding was way too damp.
Should I wait to feed him till tomorrow since I mucked with his tank today?
it looks like you are using an acurite which means the reading is above 90 percent.
i would, whenever you decide to feed, take a hair dryer and air out the substrate to dry it out. make sure you put it on low so the substrate doesnt fly everywhere.
