I think that many people are underestimating just how dry it is here (I live in Southern California, so I know). This used to be a
desert, where no one should be really living anyway, if you think about it. But I think the largest effects of RH and stuff are "equalized" by the effects of air conditioning, which puts many of us on the the same kind of playing field, for the most part.
So keep you pu-erh in the closet, and maybe try cheaper tricks like the medusa method or something...but make sure there's ventiliation (though I doubt in such dry climates the risk of mold is a high possibility). Aging pu-erh in North America is such a new phenomenon, we really won't know the effects of aging in different regions for a few more years or so.
So my advice would be to just accept that your pu-erh isn't going to age as fast as it would anywhere else, and if you can'ta accept that...mail all your pu-erh to me!
