I do use sorgum moss in my BP's warm side hide, but this time of year the humidity can be a real pain in the rear. I have hit on two things that help me keep the humidity right. I bought a small humidifyer and run it 24/7 in the apartment. Also, I picked up one of these:

I bought the small size, and I put damp, almost wet, papertowels in it. It realeases humidity without getting the substrate wet, and the design keeps Bacchus from getting to the wet towels inside.

Hope this helps.
