SO I have two AP T10's with 80 watt RHPS and cant seem to get the hot spot up past 85 without overheating the cage and having both boas plastered to the cool side. Anything over 85-87 and it starts getting up to 83 on the cool side.
Although on the same note both boas Never use a basking spot..My female wont use the warm side even after a big meal.She sits in the 80-81 degree side but has never had a problem.I just moved the little male into his new cage, he is very active and is all over the cage right now, but rarely used the UTH when in the small cage.
So should I even worry about it and just leave it at 85 degrees on the hot side?

I also have one AP T8 with a 40w RHP and its also has the same problem. I did put in a kitty litter pan hide on that side and its up to 89 on top the hide and 81 on the cool side.So at least this cage is stable..
