This block of organic CoCo Coir is the perfect soil-less growing medium for some of your hydroponic plants. Tomatoes love growing directly in this stuff with no other additions. Other plants would rather have some perlite mixed in to assure a dryer root zone and thorough drainage.
One of these blocks will give you more than 2.5 cubit feet of growing medium once water has been added to it and given time to expand. As with all CoCo Coir products it is recommended to wash the coir a couple of extra times before planting. It is also a very lightweight product which makes it easy to store and move around.
