Coconut Coir Brick Per cubic yard: N/A Per 10lb compressed brick: $37.99 Compressed coconut coir can be used in potting mix or as an organic soil amendment. Once water is added, it will expand and retain moisture, being able to hold on to 10x its weight in water. It can be used as an alternative to peat moss in soil blends. Coconut coir can be used on it’s own to sprout seeds, propagate plants and provide support to the root structures of hydroponically grown plants. Grown in a tropical climate, this does increase its saline (salt) content, so a few rinses prior to use is recommended. Compressed coconut coir brick is available for a limited time.
