Similarly, even with the UK's awful weather, I've got mine consistently
down at 30 to 31% RH in my garage. It's a separate building at the end
of my garden (i.e. no nice dry buildings attached, just more garages),
with insulation and some care over the vapour barrier, and a domestic
dehumidifier extracting half to a pint of water a day. With the last
week's rather nicer weather and the heating on to cure my rudder leading
edge layups, humidity has been in the high 20's %RH.
It does dry you out in full togs and a mask doing layups, though. And
keeping the workshop cool with 6 strip light tubes on needs an extractor
fan - even when it's sub 10C outside.

I have found that with a relatively cheap dehumidifier, it is quite easy
to
keep the workshop around the 40-45% humidity level and it is not only
good
for epoxy strength, but is also more comfortable to work in.

Alex,
As stated in my manual the humidity should be below 70% maximum
and below 60% for best results. That is, the lower the better. My
understanding
is that it affects the strength.
