What You Get in a Canna Coco Brick Package Two bricks, forty litres. Each compressed brick opens out to 20 litres of medium, and the package holds two of them. A fracture line runs down the middle of each brick. Break one in half and you make 10 litres instead, when that is all a run needs. Why This Canna Coco Coir Expands So Fast The hole is the point. A brick with a hole through it has more surface for water to reach. It takes up water and opens out faster than a solid block. The bag it arrives in is the vessel. Open it, pour water through the hole in half litre steps, then lift it by the carry handles. Lukewarm water speeds the whole thing up. Beyond convenience, two processing choices matter. It is washed and buffered, so the salts are gone and the cation sites are already loaded. The feed you give reaches the plant rather than the medium. It is not steam sterilised, a deliberate choice CANNA makes because steaming strips the natural defence a medium holds against moulds like Pythium. The coco is RHP certified for professional horticulture. Key Features Two 20 litre bricks: Forty litres expanded per package, or 10 at a time on the fracture line. The hole speeds absorption: More surface for water to reach, so it opens faster than a solid block. The bag is the soak vessel: Add water through the hole in half litre steps. Carry handles are built in. Washed and buffered: Salts rinsed and cation sites loaded, so your feed reaches the plant. Not steam sterilised: CANNA keeps the natural defence a medium holds against moulds. RHP certified: Cleared for professional horticulture, free of weeds and pathogens.
