Coir (from Malayalam kayar, cord) is the coarse fibers extracted from the fibrous outer shell of a coconut. Coir is a 100% natural and renewable resource. It has spongy characteristics, possessing excellent air space and drainage with a water holding capacity of > 70%. A compressed brick, block or bale should be soaked in water for at least 15 minutes before using. Coir can expand 5 to 7 times in volume. Make sure you have a large enough container when soaking your coir. Coir can account for up to 40% of a potting mix, so add it to your soil or as an ingredient of your potting mixes. Always keep the coir that you don't use. Coir is a material that will keep its properties and can be stored/covered for several years. Coconut coir helps develop more elaborate & stronger root systems. Ph balanced mixture easily holds nutrients and gradually releases them to the roots. Saves on fertilizer by up to 30% compared to rock wool. It significantly reduces root diseases. Doesn't contain weeds, seeds, or pathogens. High lignin (>70%) and cellulose content prevents oxidation and shrinkage. Contains organic compounds unavailable in other hydroponic mediums. Replaces the use of sphagnum, and is superior to peat moss and rock wool for structural stability, water absorption and drainage, cation exchange capacity and electrical conductivity.
