We dry our lumber to 5.5% MC. We store our finished furniture in a warehouse in a town with an EMC of 14%. No climate control (no heat or cooling - just a roof, walls and a door). The furniture is finished with NC lacquer on all surfaces.
1) How many weeks can the furniture be stored before it is at 14% MC?
2) If the wood furniture is at 14% MC and we truck it to Las Vegas, Nevada and store it at 4% EMC, how fast does it move from 14% to 4%?
The construction allows for the movement associated with MC changes from 4% to 14% and back. However, the wood itself can crack even if unattached to anything else if it loses or gains moisture too fast. I have read all about MC and EMC and their relationship to RH and temperature. The big question is: how long?
The wood species is Nothofagus pumilio, specific gravity .49, Janka hardness of 990. Let's say the ambient temperature is 95 degrees Fahrenheit.

When the lumber is dry, do you close stack and wrap in plastic to keep the moisture out, or at least slow down the moisture gain?
