Coir Blocks


Coir Blocks

This premium washed low-EC coconut coir is a biodegradable and environmentally sound substitute for peat moss. Compressed blocks of coconut fibers (coir) swell to eight or nine times their original size when placed in hot water. The fibers are quite short but have excellent moisture-retention capacity. pH 5.0-7.0, electrical conductivity of less than 0.5 S/m.

Use in potting mixes or to add organic matter to your soil. Improves aeration and nutrient retention. Easy to store and ship. Coir has been commended by the Wildlife Conservation Society as ecologically sustainable. Each block expands to approximately 2½ cubic feet once hydrated.

To hydrate, set up a large container with 6–8 gal of water. Allow the block to soak for about twenty hours, or until it’s wet through and breaks apart.
