I got rid of all the undertank heatpad I have. I am only going to use the 60w incandescent light to heat one side of the tank during the day. The room I keep my snakes in is always around 75-80 degrees anyways, will this be sufficient for San Diego and Sonoran Gophers? I hope only one heat source will work for them. That picture of the poor snake convinced me, Thanks for the help.
