Contrary to popular assumptions of higher levels, my lot do very well between 45 and 65 % humidity which I control via spraying their enclosures manually or having a heat source under their water bowl. Up here, I have found shedding issues with humidity constantly under 40%, but Im not sure how that will work in the cooler climates.
Feeding for adults is once a week on an adult mouse ~40-70gm but I have heard of other variations too. Don't be surprised if you get a difficult feeder as I have found several and it takes a bit of fine tuning of a variety of husbandry requirements that can be the cause.
Plenty of hides in a taller enclosure recommended and if a heat source is required, I aim for a top spot of 34 and a min of 22. Heat for me is provided by heat cord and is only on 3 months of the year.
All in all, a stunning snake and very rewarding to keep
