ok this is confusing me cuz i asked this wuestion a while ago when i got my fist corn and I thought that the temps were supposed to be cooler then a ball pythons and for a while i didn't have extra heat over the corns because the room temp was in the 80's already. now the corn care sheet on this site, which i was told to look on says this
"Temperatures & Heating
Provide your corn with a basking spot of 88-90° F and an ambient (background) temperature of 70 - 75° F. The ambient temperature should not fall below 70° F. It is vitally important to KNOW the temperatures at which you are keeping your snake(s). DO NOT GUESS!! A great way to monitor temps is to use a digital indoor/outdoor thermometer with a probe. Stick the thermometer to the inside of the cage on the cool end and place the probe on the warm end, and you'll have both sides covered at once.
There are several ways to go about heating the enclosure: undercage heating pads, ceramic heat emitters, basking bulbs (both regular daytime & red "night" bulbs) are just a few. Use thermostats, rheostats and/or timers to control your heat source. Do not use hot rocks with snakes as they often heat unevenly over too small of a surface area & can cause serious burns. "
infront of me i have a book"Corn and rat snakes" by Philip Purser that says that says the temps should be 82*-84* on the warm side, yet i was told that , that was wayy to cold for a corn. so you can understand my confusing now reading this thread...
