Last night I began the process of switching from stand alone tubs to a 4 shelf 15/32qt rack from Herptastic Reptiles. I am having a problem dialing in my temperatures. The rack comes with recessed heat tape and I have it connected to a Herpstat 1. My temp probe is in a small pocket routed out of the rack shelf so it can sit directly against the tape. My herpstat is set at 88 degrees. I'm able to get a fairly consistent reading on the tape and am providing a hot side tub surface temp of approx 90. My ambient temps though are nearing 84 degrees, is this dangerously high? In the past in my standalone tubs I maintained ambient temps at 80.
