I just bought digital thermometer/hygrometer from Walmart. It is a national Geographic one that was about $20. They didn't have the accurite brand here in Canada. I am just using it for humidity readings as I have two pretty accurate thermometers.

My question is where do I place the unit to read. I have in up a couple inches in the middle of the cage. Should it be middle or cool side or hot side? Should it be right on the floor or up a couple inches?
