Grow!T Coco Coir Mix Block – 25 L (~4.5 kg)

The Grow!T Coco Coir Mix Block by Hydrofarm delivers a clean, compressed medium that expands to approximately 2.5 ft³ of planting mix when hydrated. Made from 100% coconut husk fiber, it offers excellent drainage, air porosity, and water retention-perfect for strong root development in herbs, vegetables, flowers, and hydroponic systems.

Despite its compact size (approx. 11 × 11.4 × 5 in), this block is lightweight for easy handling and storage, yet expands into a full-sized grow medium ready for use. Suitable as standalone potting mix or a soil amendment to boost aeration and moisture control.
