How dry is too dry? (And how do I fix it?)

[Striving Spark]

Hello,

That's great Autumn is doing well. The desert sand is probably the type that is made of calcium which will clump up. Usually that type of sand is notorious for causing impaction if ingested. Washed & sifted playsand is a lot better if you are wanting some type of sand box.
Humidity sounds fine. It is normal for it to fluctuate like that. At 20%, that is pretty low. You can let it get into the 30%. If she doesn't have a respiratory infection, then keeping the humidity at 30% or so is perfectly acceptable.
The F10 is a great cleaner, very safe.
I hope she has gotten her appetite back!

It's quartz sand, actually - supposedly natural desert sand, at that.

The humidity is sometimes reaching 30% but usually is more around 20%. Literally nothing I've done has been able to change this.

That 20% is fine -
