i recommend using a lower wattage che, unless the room is cold and you need 100 watts. i kept arboreals using 40 watt che's (that's in a heated room though). when you can, i would use a good thermostat like helix,ranco,etc to regulate that che. use a decent themometer to keep an eye on the temps like taylor,cooper,accurite. i would put the thermometer probe on top of the substrate if your heat source is overhead.
