it'san exo terra LCD thermometer, and the other is also exo terra but a different type. I have the both placed inside on the back wall if the tank, near the subtsrate, the warm side reads about 84, and the cool about 78-80, the warm side is noticably cooler to the touch. Would the snake be injured should it burrow in the warm side? the UTH is only covered by the substrate. would this be an issue if the snake was to press right against the glass?
