well ihave a rheostat (which sucks) but with that and piling up dirt over the pad, im able to keep it at 95 or lower, it usually fluctuates from like 88-94/5. but someone from rtb.com said 92-95 is a good hot spot for boas, so i guess i'll wait to get a few more opinions on that. shes usually in the coldest corner though where its only in the mid-high 70's. idk, i think im just paranoid with baby snakes, we accidently killed my first baby cornsnake from over feeding when i was 10-11, so i think im just freaking out lol
