Ok so I took some temps of Twinkles tank and on the side with the UTH it ranged from 88-90deg, and on the cool side of the tank it ranged from 82-86deg. overall tank temp is 80.6deg... Humidity has been a steady 55-56%.. All the readings I took were from ground level.. I looked a all the substrate I have, and I have mulched cypress (which is in the tank), dry aspen, and dry coconut fiber (last two came with her)
