I currently have a thermostat and humidity gauge in the tank but i have yet to purchase a rheostat.. i was thinking about turning it on only at night while my blue night lamp was on, it keeps the temp at about 85 but i figured it would help with it on, after looking at that forum tho.. i dont think i should be putting 115degrees right into astro turf then my snake.. i think i will just hold off with putting it on until i pick up a rheostat... thanks again
