How hot do those get though...? I'm second guessing myself on my own frogs' temps at night too, though I still think 73 at night is not too low I just don't know if they're used to it yet, and I don't really want it getting lower than 72 at the most. I did read somewhere on here that someones WTFs got to 68 or 69 at night and seemed to be perfectly fine, but I don't even let my African violets get that low at night and the frogs will wind up being in the same room as them.
