We would appreciate any ideas that you can put forth
regarding adding humidity to wall showcases (4' x3').
They currently house organic anthropological artifacts
but the humidity has dropped to 25%.  They usually live
at 45-50% in storage.  The cases are obviously not
sealed now and the problem of building a microclimate
is that the temperature fluxuates from 72-80o due to
the floodlights outside the cases about 6' away and
the heating arrangements for a large lobby with
doors to the outside.  With that much change in temperature,
the carrying capacity of the humidity might go over 50%
and begin mold problems.
I am listening for any suggestions but please post them
to my personal address rather than clutter up the
list.   Thank you in advance,
