100mm Coco Coir Discs – Triple-Washed, Fine Tilth, Low EC | Peat-Free & Biodegradable
Grow Sow Greener’s 100mm compressed coco coir discs offer a clean, sustainable, and high-performance growing medium for seed germination, cuttings, or small plant propagation and microgreens. These discs are made from 100% natural coconut husk fibre, triple-washed to ensure a low EC (electrical conductivity) and a fine, even tilth—perfect for sensitive seedlings and roots.
Each disc expands on contact with water to create a breathable, absorbent substrate that promotes healthy root development without the need for peat, synthetic additives, or plastic pots. Compact and easy to use, they’re ideal for seed trays, small pots, or transplant cells, indoors or out.
Whether you're a hobby gardener or professional grower, these coir discs offer lightweight, compact and mess-free storage and are an eco-friendly alternative to traditional peat
