I got a couple 2 oz. tubes of the Heartfelt hydration beads, and used distilled water to "prime" them, and they are slowly bringing up my humidity in my humidor.

Question is, I currently have a shot glass of 50/50 in the bottom of the humidor, and the "filter" that came with the humidor is "primed" with 50/50.

So, the question is, do you think the 50/50 will "contaminate" the crystals? I am assuming no... but have read that the Propylene Glycol could "clog" the florist foam filters... so I thought I would ask if there is an issue with the beads.
