yea, beads are the way to go. i have three desktop humidors: a 75ct, a 150 ct, and my baby, a 300 ct.
my smallest i keep my cheap, nasty smokes in at 65%
my middle size is for my good NC's and they to are at 65%
in my big one, i keep all my CC's and Premium NC's. but those i keep at 60%. they just seem to smoke better and for some reason the humidity stays rock solid at 61-62%. when i had 65% beads in it, it was anywhere from 60-74%
