Overall ambient temp should be in the low 80's with a hot side floor temp of 90-95 and a cool side floor temp of 80-85.
Try and get the accurite from Walmart for about 15.00 you can get a temp w/ probe and a hygrometer all in one. Be able to get readings for cool side, hot side and humidity
Sounds like your heat pad is producing good temps for the hot side.
How are you monitoring your temps??
