I went ahead and took my spare humidity controller along with a small humidifier that was in my small accelerated drying chamber, and hooked it up. Put the humidifier in the ferment can; set the controller to shut off at 78%RH, turn on at 77%RH. the overshoot puts it round 80.5% before falling. I also put a sheet over the can and cracked the lid for just a little air exchange. Will leave it here for about a month or so. The temp. in that area of the house is right at 71*F so perfect...right at 21*C.
