Rockwool is a natural media made from a volcanic rock.   The production process ensures sterility in the final product.

When hydrated, each cube has a consistent 80% Water 20% Air ratio which makes it an ideal media for hydroponics as it is difficult to over water the cubes. This prevents seedling problems such as damping off.
