Many start with 'air drying' as it can lower the future kiln drying costs yet have it properly finished dried for quality work. Others like to speed up the process and quality and use the wood sooner while keep a better quality product by having them Vacuum kilned dried. For note, many decades ago houses were open to the outside air allowing moisture outside and inside to equalize. So outside air dryed wood became the same Humidity as inside; like 75% to 85% 'Relative Humidity'(RH). The 'moisture content in wood' being(MC) 14%-18%. Now we have tightly sealed homes with moisture percentages more like 35%(RH) or 7%(MC). If wood is placed in this changed environment it's prone to movement that will cause distortion as it continues to dry unchecked. How bad that will be depends on the wood and the change in RH thus MC. So that 58-64% RH = 11% MC. 46-52% RH = 9%MC, 32-39% RH = 7% MC, 25-32% RH = 6%MC. Drying wood with proper conditioning, and the correct drying process, will prevent this movement. Once the bound water is removed it tends to be conditioned for future moisture changes. Meaning in part what is hard to get out is hard to get in, and maybe easier to get back out should it get in. Why? Kiln drying causes a collapse of the cell walls, inhibiting the rehydration of the cells at later times. *Also note: "Air Dried Lumber's" cell walls are intact, retaining it's hygroscopic nature. Thus showing a vacuum kiln not only dry's faster and safer but with better quailty than some other kiln types. .
