Boveda Packs Regeneration

The ratio won't change a bit. It can't. A saturated salt solution (which is what Boveda packs are) can only ever be the RH it is. The reason that's a constant is because of the volume of the Boveda packs. You couldn't get enough water in one of those packets to dilute the salt far enough that it wouldn't continue being saturated. (Saturated chemically speaking.)
Different salts achieve a different RH over themselves based on their composition. Sodium Chloride, table salt, yields 75.67% RH at 10*C.
This is a really good read for all stuff salt/RH related, and will show you guys the different RH values for different salts.

What I've always wanted to know, and I started doing experiments when I was developing the HCM beads, is "can a brother mix salts and make a custom RH?"
I never finished the experiments, so I never found out.
I'll figure it out one of these days if I'm ever so moved.
It might seem like a really stupid question, but the answer to that question, coupled with some charts and graphs, would be a boon for us cigar hoarders. It'd open up a huge amount of opportunities for do-it-yourself humidity control.

Actually, you can, Scott. Although keep in mind that this pack was allowed to absorb water and expand beyond it's design parameters. Hygrometer and battery are new, and was calibrated with the Boveda 75% calibration kit just prior to placing in the bag with the expanded pack a few days ago.
