In the freezer (January) it will sublime, lol
I understand what you and Tony are saying. Will wood season if frozen? Yes. Will it season as quickly/efficiently in sub-freezing temperatures as it will in hot temperatures)? No, not in my opinion. Will it get to 11% MC? Eventually. The evaporation process is much faster than the sublimation process. If it weren't, we would not have kilns to dry wood, we would have freezers instead.
Will wood season quicker in Yuma AZ, or Umiat, AK?
