SEASONING;reduces moister
Air drying- it is where the timer is leaved out to dry on its own so natuarlly get dry. It costs less but can easily split or crack, and it extremly slow!

Kilm drying- it is wheretimbers get stacked up on each other and put into a kilm (oven) where we can control the heat that gets put into it.It can cost abit more as you are using heat to dry the timbers out.
