"Batten the hatches limeys. Post response ahoy!"
I have read it in a article on legal and health issues concerning rental property in Germany regarding mold growth on walls, and how to prevent mold growth.
I have seen houses and apartments with heavy mold growth on walls in Europe. Some of them came through leaks in walls and windows, others simply from rooms not having been aired enough. If mold grows on walls, it can also quite easily grow on tea. As we have read about on numerous occasions, such as right now from solitude.
It is entirely up to anyone to ignore pumidor experiences such of the one of solitude here - i personally would not want to go through this.
*Solitude stored their tea in a separate building. This is not the norm.
Here are the first two links i found when briefly googling "mold and poison":http://www.cdc.gov/mold/stachy.htm
* What are you trying to prove with these links. I read them both and still do not understand. Are you simply trying to emphasize the danger of certain molds?
Or that too high humidity is a bad thing? http://home.howstuffworks.com/home-impr
Basically - with the use of pumidors we are dealing with too many unknown factors since pumidors are a rather recent invention to artificially increase the aging process of Pu Erh by trying to copy climates of geographic locations in which Pu Erh has aged well naturally. Yet we have no scientific data, or long term empirical evidence of the effects such pumidors have on tea.
We have though numerous examples of how the use of pumidors went wrong, which at least shows us that it is a very risky undertaking.
*There are risks in all endeavors. Mitigating those risks is another matter. If one in these climates is to keep a sizable amount of pu for some time, they have not option.
Some climates in the US, for example, are definitely less than ideal to age Pu Erh. What i would suggest is that some of you may get together, and find a storage place in a better suited, more humid and hot climate in the US - such as Florida, share the expenses, and store your tea there together. Or that somebody who lives in such a location may rent out storage space for Pu Erh lovers who live in not so well suited locations.
* If I could, I would send it to Hong Kong to age.
I have heard that in Malaysia there are storehouses in which Pu Erh aficionados can rent space to store their tea long term. Would that not be something that you can do in the US?
*I think there are not enough people to make this practical. Who is going to check-in on cakes? Rotate them? A shame, but it is unlikely to happen. If I could, I would send them to Veracruz. I seems a climate good for cigars is a climate good for pu.
*There are about 100 bings in my basement in a plastic tub. This will be the second year they have been stored at about 72% humidity. Once we get a nice rainy day, I am going to give them an "airing out." Then I will let you know how much mold they have.
*The first link you provided gives the following advice:
*"If you have mold in your home, your nose is one of the most inexpensive devises you can use to detect it." Your point about mold growing on walls is a bit flawed. The reason for the pumidor is the lack of humidity. Many rooms/ basements in the winter have the opposite problem. Usually there is some sort of home heating system that dries out the basement. It is a whole other issue if one has a leaky basement. I highly doubt you will find many TC'ers willingly storing their tea in moldy basements!
One of the guilty pleasures I have found of having this storage system is enjoying the incredible smell. Our local museum curator of Chinese art came over for tea last month. Her aunt runs a tea warehouse in Hong Kong. Just as she poked her nose in the pumidor and took a whiff, she exclaimed, "This smells just like my aunts warehouse!" Now hopefully her aunt did not have a warehouse full of moldy tea. My guess is she does not!
