Temp gradient / air vs surface difference ?

[KMG]

I dont know why a heavy snake can't use a uth. My 30lb uses one just fine.

Is the rhp on a tstat? Is that the probe that is directly below it on the ground?

If it were me I would place the warm hide directly under the rhp and keep the top at what you want the hotspot to be. That should give it plenty of heat in the hide.

If I put the hide directly under the heat, the roof of hide gets around 110f to get around 88 inside it? If I turn it down the cool end will be even less than 75! Using a mat for hotspot would make my life easier but it states everywhere no mat inside wooden viv even on a stat, thermal block burns etc etc... The heat radiator is on a dimmer rite now for testing which does the job. Is the very cool end being 75 a problem? He doesn't have to use it?
Thanks
