so i have never tried calibrating my hygrometer. it is a caliber 3 and i was under the impression it would be pretty close to in range. so i bought 3 cheapo hygrometers and i figured i'd get an idea of how close they were to my 'good' caliber 3. they were off by 1-4%. compared them to my house hygrometer and they were all off from that. so i looked on the intraweb and found a couple of sites showing how to do it with a capful of salt and a little water in a ziplock bag. well they are all way off after 18 hours, like reading 65-68. i know they say to just use the offset but are these too far out? not sure they respond linearly. do these numbers sound way off? my cures have been less than optimal. i am thinking using the caliber has made it so i have kept the jars above the cure zone for too long. my long term storage i have boveda 62's in and one that i had in the closet for 4 or 5 months. the pack is still nice and soft. i have read that when they have been used up, they get hard. thanks in advance...
