W2G Coco Brick
The W2G Coco Brick is a premium compressed coco coir medium designed for professional horticulture. Manufactured to RHP standards and buffered with calcium and magnesium, it provides a stable and reliable substrate for seedlings, cuttings, and mature plants across hydroponics, pots, and mixed media systems. Each 5 kg brick expands to approximately 60 litres of high‑quality medium when hydrated.
Enriched with Trichoderma fungi for improved root health and resistance to soil‑borne pathogens, W2G Coco delivers superior air‑fill porosity and free‑draining structure. This balance of aeration and moisture retention supports vigorous root development, consistent nutrient uptake, and strong plant performance. Naturally renewable and long‑lasting, it offers both growers and the environment a sustainable alternative to traditional substrates.
A stable, aerated, and biologically enriched coco substrate that expands to 60 L from one compact 5 kg brick.
