if you want a good thermo go to lowes. they have a home use one that does indoor/outdoor temp and indoor humidity. you have to keep the thermo in the cage but its not that big or ugly. so i put that on the cool side and it reads the cool side temp and humidity. and theres a probe and i run that to the hot side and tape it to the floor of the cage. it has double sided tape on it from factory. and it works great. for 12 bucks i couldnt beat it. and i just bought another for 12 bucks again for a new carpet im gonna be getting. they often have bag sales and other coupons too for 20% off so keep an eye out. saving money is great.
