the only thing i would question about that is the packet is in like a "pocket" of that upper tin... i wonder if the chemistry in the pack itself needs some sort of fresh air to stay working....
and i guess another thing to back that up would be why would they send them to you active and you have to seal them yourselves???
i wonder though... wheres squigg! haha i wish there was a technology on this forum where you could like call @ people, if ya need em. haha.
I have been using these for awhile (in jars). They make smaller packs that work well in mason jars under a different brand easily found on eBay (but I had already used the Bovedas to store my cigars, and am simply looking for an appropriately sized jar to use them).
I can explain a bit how these work.
The pack is essentially a RO membrane enclosing hydrated sillica gel (the stuff they put in packs in your shoeboxes to remove moisture). The membrane is tuned to drive osmosis of moisture through the membrane until an equilibrium of a particular humidity level has been reached outside of the package. The chemistry here is super advanced so I'll skip explaining it.
Basically there is no need for air flow, in fact it's probably best that there is less to reduce the oxidizing power of oxygen (which will react with your
terpenes and other actives) and to avoid loss of volatile
terpenes themselves through evaporation.
The pack itself requires no fresh air whatsoever, this would work in a nitrogen atmosphere (totally inert). It simply releases moisture until the humidity outside of the pack is high enough to prevent further flow of moisture by osmosis (ie until the osmotic pressure on either side of the membrane has equalized).
Likewise if conditions become too wet, the osmotic pressure is once again out of balance and moisture will flow freely into the pack (where it is reabsorbed by the sillica gel).
These last much longer than 60 days if properly cared for. For instance if you were to enclose your bud as in the video above and just leave the thing closed, it would very likely last upwards of a year or more. The problem is that when you remove the lid, you lose a bunch of moisture--the more you do this the sooner the pack will be spent. Keep in mind that moisture will flow out more quickly the further from the prescribed humidity level the atmosphere is as this process follows an equilibrium behavior. Each additional molecule of water released in a sub 62% humidity atmosphere will be released more slowly than the last, which is to say that the further away from the prescribed humidity you are the faster your pack will shit out water molecules.
See:
Le Chatlier's Principle (even for non scientists this is a helpful principle to understand for many reasons--I highly recommend you do some reading on this until you understand it).
Over time the moisture stored in the pack will eventually deplete--or secondarily the membrane itself will be spent (this is the absolute limitation on life of the pack).
I do recommend using the 62% packs for curing as opposed to the 55-58%. I have had better results with the higher humidity version.
Any other questions about these things, get at me.
