From my experience and having used UMAI bags a lot I avoid case hardening by placing two bowls of water in my frost free refrigerator laced with salt. The salt cuts back on bacteria that can collect in the water. I have a small USB fan blowing over the surface of the water distributing moisture. I have had great success with this technique. Although UMAI bags are wonderful and keep a pretty good humidity inside the bag if your refrigerator tends to run on the low side adding water will help and avoid case hardening.
