You should not have a temp variance of 7 degrees on one side of the tank. I.E. you said it runs from 87-94??? Thats way too much change. As the others said that should be kept right around 90 and your cool side 82-84. The advice given on hides is also correct, make sure they are identical and provide appropriate security- dark and snug the reptilebasics one while plain and boring are very functional and good for the snake. They are also inexpensive which is a plus. Your UTH is on a thermostat i hope?
