That's a very good point. The first tank I set-up had a small UTH with no controller. My room temps were 78-80. The first time I checked the UTH with a temp gun it was cooking at 103F. Fortunately, I caught it before my snake got burned. So yes, depending on alot of factors, ie. the individual heater, ambient temps, type of enclosure, etc... you may be able to get away without using a controlling device, but it is going to be a gamble that only you can determine whether or not you are willing to take. You can get thermostats that range in price from $25-30 all the way up to over $300. A relatively small investment for the health, welfare, and safety of your pet...Originally Posted by tizzle89
... buy a zoo med uth for a 10 to 20 gallon cage.. on the glass right over the uth in my cage gets to 93.1 max with no light.. but like i said my room is 55 degrees if you have an 80 degree room then yes you would push alot more heat. substrate i use is dirt with coconut fibers..
