My thermostat is usually porgrammed so that the mat reaches about 90F but then the temp of the bedding in the enclosure is only about 70-80F in the hotside. I've seen a video from the channel Snake Discovery on Youtube (that appeared very professional and well-informed) and the girl from the channel said to set the tub with the thermostat probe inside the enclosure above the heat-mat under the bedding. This though, does not change my problem since whatever the case the temp of the actual bedding is always way lower that the temp of the UTH.

Do you think I should still put the probe sandwiched between the mat and the enclosure as you said and set it above 90F so that the temp of the bedding and hides where the snake actually is rises too? Or maybe I should use just a half as thick of aspen fiber layer?
Yes, the probe goes OUTSIDE, for the reasons I mentioned above.

Also, the substrate temp is not important. The ACTUAL SURFACE temp is what's important
