I'm planning to get a hoggie soon (my first snake!) and after some research, I still have some husbandry questions. Can any hognose owners help me out?

- for a PVC enclosure, should I use a RHP or UTH? is just one of either of those sufficient for a hoggie? or do I need both?
- I'm considering getting a herpstat. For whichever heating setup you'd recommend, which model is appropriate? Would an intro+ be enough? I don't really know which to get.
- is ambient humidity with a moist hide sufficient? (is the moist hide for regular use or just during sheds?)
- should I make any modifications to a PVC cage? someone suggested I make additional vents or widen the existing ones for better airflow for a colubrid. In general, is there anything else you need to do with PVC other than put holes in it for wiring?

Thanks in advance
