Thank you everyone for all the helpful recommendation! I do think I'm going to buy another small UTH for the cool side because sometimes the room can get quite cold. I just want the best for my snake!
EDIT:
My whole set up will consist of the following:
1. UTH heater (40 gallon)
1. Red bulb to maintain proper heat
and maybe I'll buy a small UTH for the cool side, so I can maintain 80-84 degrees throughout the day.
Also where does the ambient temps fall into all of this? I know its a silly question!
