You're very welcome! You'll probably want your ambient temp closer to 78-80 F, if possible. It's good to hear that you were able to boost up the humidity, though! For target humidity, I believe the general recommendation is 55-60% when not shedding, and 70-75% during the shedding process. However, I will say that from my personal experience, both of my BPs were still struggling with their sheds a bit when I was staying within these ranges. I currently maintain humidity at around 75% when not shedding, and go up to 80-85% during shedding. They've had perfect sheds ever since, and no issues with respiratory infections or scale rot. I think the key to avoiding these complications is that you want things humid, but not WET. If there's a lot of fogging/condensation on the sides of the tub, that's too much. If there's a really soggy patch on the substrate, clean it up and don't let your snake sit in it. But if things look pretty normal, and it doesn't feel like a mini sauna when you open up the tub lid, then you're probably okay.
