Depends on wood,size and your weather. I usually leave mine whole until it is completely dry. They seem to crack and split less . If they do crack or split you might be able to work around it. I leave my dragoon wood in the rafters of the barn , winter time is drier here in Fla and lower humidity. Smaller pieces cure in a few weeks and larger 2" dia stuff might take a month or two. The sunshine is more for bacteria and fungus that need damp ,humid conditions to thrive. You could "cure" smaller pieces in your oven at low heat if you wished to speed things up, watch and don't burn them,LOL
