Medium grade Dyna-Rok II is a versatile, absorbant, earth friendly growing medium made from the fossils of ancient single-celled plants called diatoms. These fossils are a natural source of silica and plant growth boosting minerals. The majority of the medium doesnt decompose, however, holding as much as 150% of its total weight in water. This makes Dyna-Rok II an excellent choice as a stand alone medium or as a soil amendment.
