Grodan Tapered Cubes in Tray – 42 contains 42 rockwool starter cubes arranged in a single propagation tray. The tapered shape, wider at the top and narrower at the bottom, supports easy transplantation into larger growing blocks or slabs by allowing cubes to fit securely without root disturbance. These cubes deliver balanced water retention and air-filled porosity to promote root growth. Made from spun stone wool fibers, they arrive sterile, pH-neutral around 5.5, and dimensionally stable even when fully saturated. Suitable for seed germination and vegetative cutting propagation in hydroponic, aeroponic, or soilless systems.
