That's a lot of crammed in text to plough through .. I'd try and start typing in sections or even Bullet points?
Sooooo ... there are so many issues here ... I'll prioritise..
Anyways I'm wondering if he's just two warm ...
Are you using one of those stick-on , plastic round shaped thermometers ?
Is the heat LAMP regulated by a thermostat?
Is the heat MAT regulated by a thermostat?
Are both heat sources at the same end or are you heating BOTH ends ?
I'm short of time but note it really needs two , similar/identical sizes hides , one at the warm end , warm at the cool end
