What Is Organic Coco Coir?

Also known as coco peat or coco soil, organic coco coir is the soft, sponge-like material extracted from coconut husks. Naturally biodegradable, pH-balanced, and OMRI-certified, it's sterile, safe, and suitable for everything from hydroponics to worm bedding.

It’s available in bricks, blocks, discs, and more—each form expanding significantly when hydrated and delivering exceptional aeration and water retention to your soil.

Top Benefits of Organic Coco Coir

Retains Moisture Without Drowning Roots

Coco coir can hold up to 9x its weight in water yet drain efficiently—ideal for keeping your plants hydrated without waterlogging.

Improves Root Aeration

Its porous structure allows oxygen to circulate around roots, which helps plants develop faster and stronger.

Neutral pH and Sterile

With a pH range of 5.5–6.8, coco coir supports nutrient absorption and remains free from fungi or harmful pathogens—perfect for clean, safe gardening.

Renewable, Eco-Friendly & Peat-Free

Unlike peat moss, coco coir is a by-product of coconut harvesting—100% sustainable and gentle on the planet.

Boosts Soil Texture and Plant Yield

When mixed into soil, coco coir lightens compact clay, improves drainage, and enhances nutrient access. Reusable for multiple growing cycles.
