Being brand new and never even rolling my first cigar, I have purchased some leaf to get started. I have the leaves in a 100 qt. cooler (I call my "leafador") and am using the silica cat litter in a stocking for humidity. What relative humidity should I be aiming for when it come to storing the leaf? I live in Colorado where in the winter the humidity is probably in the 20% or below. Right now my leafador is sitting at 90% humidity and I can't seem to bring it down. If it needs to be around 70% how do I dry out the cat litter? Any help is appreciated.
