Product Description CocoWool Briquette A premium, 100% organic peat-free growing medium, containing sheep’s wool pellets from an organic flock of sheep. The 800g compressed compost block, by simply adding 10L of water, expands into compost 7-8 times its original volume. The sheep’s wool helps retain moisture, and adds long lasting fertilisation to the peat-free compost made from coconut fibre certified according to USDA1 for use in organic production. Ideal for indoor or window sill herb cultivation or simply for a cleaner growing medium.
