For christmas I got a Zoo Med UTH #RH-4 and it says not to put on plastic but I remember seeing on another post that they only say that cause it wont stick properly to the bottom of the tub so he just taped it on which I dont think is a good idea but it seemed to work for him.
I'm thinking of taping it under my BP's tub near the center where I keep the water dish so I can get more humidity and a higher ambient air temp but I dont want to screw up and have something dumb happen so I wanted some input on what could happen and what I can do to make this work.
