Please note - the temperature is not controllable on this item. We recommend also purchasing the Zoo Med Repti-Temp Rheostat to control temperature setting. A rock heaters function is to facilitate digestion. A rock heater should never be the sole source of heat. Never cover or bury the rock heater with anything. If your reptile never leaves the rock heater then your terrarium is too cold and you need an additional heat source. Designed for use in glass terrariums only.
