Wow ... quite a lot to take in for a dyslexic / aspie ..
I noticed a few little things ..
First off I'm thinking your layer of substrate maybe far too thick .
In the uk I think it's suggested at 1" , two inch max ..
As for type of substrate .. I love using Orchid bark / Repti-bark .
Looks great , shows off your snake's colours , holds moisture- humidity well.
May I enquire as to what you're using to check the surface temps and humidity?
One similar to these maybe. ?
