I disagree...I said what I meant, don't put words coming from me when you don't evidently understandIf the room temp is 80-85, and he has a basking lamp that is 111 degrees (that is a little too hoy by the way...), then the temperatures should be fine. Do you mean to say that humidity will be too low in an open topped tub? That might be the case, even in a humid climate.
