Is it true that if I have air dried lumber (hard maple) in my yard that is now about 25-30% and I am putting it in the kiln with dead green lumber 50%, that the partially air dried lumber will not warp as it will be somewhat rewetted? Also, we have our lumber stacked on sticks and put into our yard which is subject to all elements (snow, rain, sun, wind). It is air drying for anywhere from two weeks to two months - will this lumber warp? I have tried to explain this to the higher up, but Iím getting nowhere.

From contributor Y:
If your lumber is hard maple and winter cut, it has probably been frozen most of the time since being cut. The moisture content will not have decreased much since being cut. If your lumber was properly stickered, immediately after cutting then covered with a lid or under cover it should not warp. I like to get my maple kilned as soon as possible before the weather gets warm. This keeps the nice white color, reduces sticker staining and fungus discoloration.
