Viagrow， Sri Lanka OMRI certified Coconut coir boasts the highest quality coir bricks made. The coconut coir bricks are composed of three different types of compressed coconut coir. This high quality， low sodium growing medium is an environmentally friendly， sustainable and an alternative to sphagnum peat moss.
