if your really worried about himidity you could add some moss, I won't pretend to be an expert and say I know what the exact humidity should be but with the container I use I do see a bit of condensation from the water dish. I'm sure I'm way higher than I need to be but his shed was perfect a couple weeks back and he is frequently out and about looking around and is active when he sees me peering in on him. I will probaly add a couple more holes to the container or move him/her into something else and lower the humidity for mine as i don't want to cause respiratory issues.

maybe KLG will shed some more light on specific husbandry practicies for us I only know what I've read from the few articles online.
