I also have a question about tub temps, and rather than making a new thread I'll just post it in here.

I'm ordering a rack from reptile basics at the end of the month with belly heat. I'm going to order a helix and set it to 94 for the warm side temps, but the room it will be in stays right around 70 (can dip into the upper 60s at night).

Should the heat from the tape be enough to raise the cold side temps?
