Ok, I've gone through many pages of threads and posts, as well as read the caresheets and DIY guides for habitats. I still cant find the info I need.

So, quick question ...

I have a 15q tub for my BP with flexwatt tape on a ranco therm set to 91*. The warm side is constant, the humidity is constant at 40% (unless shedding) but the cool side is much too cold. It stays at about 70* and went down to 68* this evening. I need a way to warm it up without putting a heat lamp on it (would melt the plastic) and without adding another strip of flex watt (would have to purchase a second thermostat). I've resorted to putting my clothing (an old shirt or a towel, a sock, whatever is clean and lying around) in the tub on the cool side just in case she wants extra warmth. She is usually in her deli cup hide on the cool side so she doesnt seem to be bothered by the temps. But I am.
