Humidity level too low?

There are a lot of different formulations to make a super absorbent polymer and it's possible that Xikar uses a rather different formulation than others, one which requires PG to maintain humidity, is something that I have heard before.

Most of the ones out there which are sold for cigar use are self-regulating around 65-70 RH with only water. The differences in formulation also explain why you generally can't take stuff from the arts and crafts store floral section and just stick it in a humidor, or, more accurately, why it doesn't give you a desirable RH when you do.

Also, going back to the formulation, certain formulations have different useable lifespans than others. Some are good for a few years, some are good for a decade before they "wear out".

Regarding some of the companies, the fact that they want you to buy their PG/water solution, when the PG doesn't do anything for the gel is classic marketing.
