I am thinking of buying a plastic enclosure from either boaphile, ap, or pro line. The ambient temps in my home are in the low 60's, so I will be using a RHP in the new enclosure, My questions is if the RHP can give a 90* hotspot inside the hot side hide? Or if the temps will have to be hotter on the outside of the hot side hide in order to achieve the 90* inside the hide? Or would I need to use a UTH for the hotspot and the RHP for ambient temps? Any experience with colder ambient temps welcomed!
