I just ordered the Heartfelt Industries humidification beads in a 65% format. Then I got to thinking which is best 65 or 70%? My humidor generally runs around 70% with the cigar savor I had in there. I looked around the forum a bit and found no clear preference. Is it worth it to return the 65% and bump it up to 70%? Just looking for opinions here. I assume this is a subjective question.
