Coco Coir briquettes, also known as coir blocks, are compacted bricks made from the fibrous husk of the coconut. These eco-friendly blocks are widely used in gardening, hydroponics, and landscaping thanks to their excellent water retention, drainage, and aeration properties.
When immersed in water, coco coir briquettes expand significantly (up to seven times their original size), creating a lightweight, porous substrate that promotes healthy root growth.
