Definitely not. I have a neighbor who buys all his wood and he will buy seasoned BUT he buys it in like April so it still has at least 6mo to season before burning.

I just bought two cords of seasoned for NEXT winter assuming it would be wet af. Tested a bunch late one night and they all tested 17-19% which generally means they are 25% on the inside. Was pleasantly surprised when I split them and found the inside to be just as dry.
