Re: GSBN:Leaving bales bare
John and all others,
My initial intention was not to say that plastering bales ASAP should
be regarded as absolute priority under all circumstances. The main
thing is to keep the bales in the wall below 20% rel moisture levels.
What I do suggest is that getting fresh dry bales bales rapidly
plastered will most probably seriously reduce the risks of an
inadvertent wetting incident.

This is an interesting topic right at present, since we're trying to
stack 1000 bales in exposed gable ends in the middle of torrential wind
and rain in California (we've only lost 20 bales to the rain). While
certainly I agree that it's best to use dry bales and get them
quickly, I question whether this principle should be raised to a level
of almost absolute priority. Habib's experiences, and our own, suggest
that the walls are pretty resilient when it comes to moisture.
It seems from what John is saying, that mold growth is jump-started in
bales that have previously experienced conditions of spore growth, but
would ask whether, or how, this influences the future suseptability of
the wall to mold. It would seem that the humidity level required for
mold would not change, simply that mold would appear more quickly, say
after two winter's wetting rather than ten? If the walls are not
to experience serious wetting in the future, is this really a problem?
