No changes in smell, perfect preservation, the 58 is just right, the 62 I am reliably informed works really well for Rosin, noticeable yield differences over 58, the resin flows better in slightly more humid weed it seems.
62% RH or so appears to be the right level for curing, per Simon in his "a perfect cure every time" thread. It works for me. Once the buds have cured to the grower's satisfaction, a few months or whatever, then a lower level can be established for storage & use. At that point, the RH doesn't matter much so long as it's not popcorn dry.
Leaving bovedas in the jars for longer periods of time doesn't seem to make any difference wrt taste & effect. Keeping the jars tightly sealed at any RH helps preserve aroma. I generally pull a handful of buds from a jar, leave 'em out for a few hours or overnight to bring the moisture content down for best smoking, grind 'em up & keep it in a tin ready to go...
I have a really hard time believing that a person coming down with an auto immune disease would have any way at all in tracing it back to a humidity pack they used to regulate the humidity of their buds. Would have been fun to have grilled him on any proof he had. And that would definitely be grounds for a huge lawsuit if it were indeed true. Also Bodeva is made up of salt and a gelling agent and has a membrane small enough only to let pure H2O move through it. I think he was just using crappy tactics to try and hype his product.
They sure sell a lot of Boveda packs to the cigar industry, I find it kind of hard to believe they could be solely responsible for that kind of health hazard. Sounds like he was bashing for the sake of self promotion.
