I face the same issue, I keep my winedor at 66rh and 68F i would like to get it down to 63 or 662 rh but cant seem to get it any lower. I have a small amount of dry heartfelt beads in there and have three solid 3/4 in Spanish cedar boards for shelves. I originally had a half pound bag of heartfelt beads slightly seasoned with distilled water. may have to try to put the whole half pound of dry beads in there and see if that helps.
