dehumidifier to control MC

How can I control wood from absorbing moisture? Can I enclose a small
portion of my lumber stock approximately for 500 board feet and somehow
fit it with a dehumidifier? or something else?

ANy body got suggestions for this problem?

Thanks in advance

Short answer is--you can't w/o finishing it.

You have my permission... :)

What, specifically, is the problem?

If you have a damp shop and store your material in a drier location,
then when you bring it from that location to the shop it's going
reaclimate while you're trying to work on it. You need a stable
environment in the shop, basically.

Sure you can. Stored wood that way up at the university. That way you knew
where it stood and which way it was going, because you looked at the RH on
the wall. If it was going to expand, you built loose. If it was going to
contract, tight.

No need for it to cycle up and down all the time, because then you'd have to
check every board and hope the interior and exterior were equalized. Keep a
good hygrometer on the wall in there to calibrate your analog humidity
control.

Actually, the way oldtimers did that was to cut a reference board at a
precise width (say 12") and simply measure its dimension periodically to
see where it was at the time...

if the humidity is below abouyt 40% then your fine. is is when it gets
higher that wood will absorb more.
but you could put a dehumidifier with the wood wrapped in plastic. it
iwll make heat and dry out the wood.

Keep it out of direct contact with water.

Sure, but why?
