Use UTH with Colubrids?

[Daybreaker]

My questions for now:

1. Who uses UTHs for their colubrids?
2. Does anyone use supplemental lighting along with the UTH?
3. How are your ambient and cool side temps?
4. If your room isn't warm enough to keep ambient/cool side warm enough, how do you do so?

1) Me! Though I usually turn them off in the summer.
2) Nope
3) Ambient temps and cold side stay about 79/80 with a slight night drop since it's colder right now. They're in the snake room that's heated to those degrees.
4) We keep it warm enough, I would think a space heater on a thermostat would work though.
