This organic coconut fiber medium offers top performance in hydroponic applications. Coconut fiber maintains a larger water holding capacity than rockwool. Just soak in water for a few minutes, and the brick will expand up to 4 times it's compressed size. It is can be mixed with grow rocks or grow cubes for a better aeration of the medium. It is very useful in intermittent irrigation systems such as Ebb & Flow. It comes in 1 lb. bricks, individually wrapped and in cases of 24 bricks.
