Do people do this? I think soon I'm going to plunge into a PVC cage for my boa as she is growing and I can't stand the tank, even though the humidity is fine, it's just very unattractive because it's old and water stained and heavy, plus she'll need bigger enclosure soon anyways.

I would rather not spend an additional sum of money for the heating element when I have a spare UTH still unpackaged. I assume it's really no different than having heat tape, or when people use UTHs on tubs? I feel ridiculous asking this, lol.
