I've cut and machined up a lot of wood for parts for things like bottom boards, boxes and covers. Some of it has shrunk a lot as it's been stored indoors, and I wondered if it can get too dry.

The reason I ask is that I'm building bottoms out of tongue and groove, and I'm afraid that if it swells much, it might make the thing too wide, or it might begin to buckle.

Thoughts?
