hey, thanks for replying.
there isnt air flow underneath the UTH. the UTH is just sitting on my carpet floor. there is air though between the UTH and the enclosure.
the enclosure is wooden by the way, so it insulates a little better than glass.
the temps at the actual base of the enclosure, under the substrate is about 95f, and surface of substrate above heat mat is 88, ambient of 78 or 79. - dropping to 76 or so on the cool side.
so its all good then now pretty much yeah?
i will be looking at getting a thermostat but nobody answer my questions about them.
