The OMRI-certified Riococo Coir Starter Block allows growers to propagate easier and faster to produce healthy plants organically. The 100% biodegradable block has excellent water holding capacity. Equal distribution of water throughout the block ensures optimum management of the air and water balance and the equal distribution of nutrient solutions. The block is made from a 100% coir fiber compressed disc packed in biodegradable cellulous paper. Natural coir fibers retain water and keeps roots well-aerated. Its open structure is maintained throughout the propagation cycle until the block is transplanted into a separate growing container.
