On another note, after reading some of your previous posts you say you do not use a UTH or "need" one. Ball pythons are not like many other reptiles that rely on warm ambient temps only, they absorb most of the heat they require through their belly, hence the emphasized need for a UTH in all of our stickies.

Further, if you do indeed have 87-92, and no UTH, your overhead lamps must either be VERY strong, or your live in a very warm climate. If the overhead lamps you use provide the majority of your heat then I can guarantee your humidity is lower than is should be.
