muddoc, thanks for the reply i will have my rack setup in a closet that is ventalated. Rght now i have my one and only BP in there. i am however putting a deposit on 2 Females from Markus Jayne this week. Anyway, the ambient temp in the closet stays in the mid too high 70's. I may buy some 3" flexwatt just in case i do need it. I am planning on building a new house next summer so i will difenetly have a seperate snake room. just gotta make due for now. thanks for the help.
