How long should I wait for cedar wood to air dry,

I would use it on a deck right off the mill. Most pressure treated wood sold is wet from the treatment. On a deck it will get wet and dry out many times over its life. Putting it down green is not a problem. Since you are using screws, the only way to attach a deck in my opinion, any boards that really split or warp can be replaced easily.
