Coconut coir bricks are composed of three different types of compressed coconut coir. This 1.4lb (650g), high quality, low sodium, sterile growing medium is an alternative to sphagnum peat Moss & absorbs great amounts of water, lowering watering frequency. When hydrated with water, bricks & blocks rapidly expand which saves you time & effort. They can be exclusively used by themselves, blended together or mixed with expanded clay pellets, perlite or topsoil. The brick will break down on its own in three years.
