I'm not sure where to begin..
I don't yet have a ball python yet but I have plans to get one in April. I'm not completely unknowledgeable, as I've spent the last 6+ months extensively researching just about everything imaginable in the husbandry aspects of BPs.. My questions are just ones that would require the already owning of one to answer, which is why I'm here
So, here's my questions:
1) in the whole glass tank vs plastic tubs debate, I think I've finally decided to go with the plastic tub, but I'm still struggling as to how to perfectly set one up. What is the proper setup for a plastic tub?

2) (This may seem like a ridiculous one) Does the amount of humidity in your tank affect the room the snake resides in?? It's gonna be in my bedroom and I'm gonna build a rack for its tub, but I'm nervous that it's going to make my room stuffy and humid all the time.

3) Can somebody please just tell me everything is gonna be fine? Hahahah. I want to do this right and I want to give this animal the longest and healthiest life possible, but I am just so stressed about doing this right.

All advice and answers are GREATLY appreciated!
