ProEarth Organic Blocking Soil Mix
A dedicated fine-particle organic medium for cohesive soil-block production.
Blocking Mix solves the physical job of forming and holding a soil block. Specialty Soils observes that it holds more moisture and dries more slowly than comparison media; that observation does not make it universally better for all seedlings.
