Rough Rule of thumb is it takes about 1 year of air dry time per inch of thickness after it was initially cut into boards. More in high humidity areas and less in the desert. You need to stack it out of the weather with slats (aka stickers) between each board to allow air to circulate. The stickers should be spaced about every 12-18” and they need to be aligned from layer to layer to prevent warping. The weight of the boards above help keep them from warping, twisting and cupping so you can put something heavy like cinder blocks on the top boards which have less weight on them. You can paint the ends with latex paint to help prevent checks and cracks in the ends. If you don’t have room inside, you can cover with a tarp to keep the rain off but it is a good ideal to make sure there is some air space above the top boards in the stack. Don’t forget to put something under the bottom layer to keep it off the floor or ground.

A year from now when it is time to run them through a planer to do final milling to 3/4” boards, it is a good idea to do initial milling slightly thicker than final dimension and let them sit for a week or 2 before the final pass through the the planer. Once you plane them, they are likely to move a little and this gives you some room to fix that. If they aren’t flat you may need to run them through a jointer befor the planer.
