Stacking off the ground and in the dry is the fastest way I have found to season wood. I bought one of those metal carports with open sides, back when you could buy one for $400, so I have had it a while. I lined the ground with black plastic to prevent moisture from coming up from the soil. I then laid pallets on top of the plastic. I stack the wood under the shed on the pallets about 6ft tall stacks. Just my theory, but I believe the tin on the carport really heats up and helps dry the wood. I can put green white oak in the shed and it will be making big cracks in 2 months. Best part of the carport is I can stack the wood in one end and take it out the opposite end so I am always burning wood that has been seasoning at least a year. This year I stacked a bunch outside the shed so I could burn the wood that had been in the center of the shed for several years. I have about 2 cords stacked along the sides of the shed, about 6ft high in the middle of the stack. The shed post help keep the stacks from falling over. Inside the shed I have about 3 1/2- 4 cords stacked along the opposite side of the shed of the outside stacks. This allows good airflow and speeds drying. I will eventually fill the shed completely with wood, I hope. I have about a cord or so of bucked but unsplit wood in a pile and I just got a load of white elm in 10ft lenghts I dumped on top of other wood to keep it off the ground. Old pic, but you get the ideal.
