Softwood that originates from coniferous trees is faster drying than hardwood, which is more dense, structurally complex and less permeable. Although hardwood is more abundant, the process of seasoning or drying softwood makes it the main source of commercial wood.
Drying wood, sometimes referred to as seasoning, is a process used for firewood and construction material. Wood can be air-dried or dried in a kiln. Too-rapid drying can cause shrinkage and wood damage. Drying time will vary depending on the type of wood, the weather and climate and the wood's initial water content. Wood moisture meters are available to determine the wood's water content.
