Slow drying is often recommended for difficult-to-dry hardwood species to minimize defects like warping and checking. However, research has shown that even with slow drying schedules, some hardwood species still develop internal checks and surface distortions, particularly when the wood originates from younger trees. These defects are attributed to the collapse of wood cells during drying, even under mild conditions.
