Cedar wood prices are primarily driven by grade, moisture content, and dimensions. Clear Heart grade (free of knots) is the most expensive, while STK (Select Tight Knot) is more economical for rustic applications. Ensure the wood is Kiln-Dried (KD) to a moisture content of 12-15% for interior use or S-DRY for exterior use to prevent warping. Additionally, the species (e.g., Western Red Cedar vs. Aromatic Eastern Red Cedar) significantly impacts the price point due to differing rot-resistance and oil content.
