My readings are off. I moved the temp/hyrometer to the center of the tank and its now reading at 80 degrees. When I probed the substrate on the hot side the top of the substrate read at 95, the cool 80. I did add a humidity cup to the mix now. I do know that Grim will need a larger tank eventually. In March I have a friend giving me a 125 gallon tankThanks for the information! Hopefully by tomorrow in the AM things will look different!
