If it comes to a choice between risking scale rot or maintaining humidity in the 40% range....I'd opt for lower humidity. 49% is FINE. 50% is not a magical number. Mid-40's is fine. Higher might be a bit better, but its not an absolute.


Just be sure to keep an eye on your snake and be aware of when its getting ready to shed so you can then take extra measures to up the humidity, such as a humid hide and/or a bowl of water for soaking.
