When curing in mason jars, does anyone use these humidpaks, the 62%, and what size, the smaller one, or larger size, nearly the size of a post card. Has any one used these with any success? They're not expensive and I saw these at my local smoke/cigar outlet. Read a little and saw them the next day. Don't hear to much on these paks, sounds like they can be very helpful. Boveda humudpaks 62%, I notice different ones, 65%, 72% and a few more. Thanks.
