Humidity, how low is TOO low?

[FeathersRuff]

I'm just asking this for assurance, as of right now I'm working on ways to keep my humidity stable. But right now as sometimes I am away for multiple hours and cant mist. I need to know what the bare minimum is for humidity percentage, just the amount that would be the lowest but not cause a risk of RI. The lowest I've seen it go when I've come back after a length of hours was 43-45.

When I had royals in exo terra vivs it would consistently go down to 40%. As long as I put sphagnum Moss in the vivs when going into shed I never had a problem

If you're around 45%, I think that is "okay"... ideally, a little higher would be preferred. I had a lot of trouble in my first enclosure with humidity. I ended up getting a decent size bowl and putting a big handful of sphagnum moss in it and then wetting the moss and putting about an inch of water in the bowl. I'd check it every other day or so and re-wet it if needed. That seemed to really help me and kept me from having to mist daily.
