This soilless production system delivers precise concentrations of dissolved minerals directly to the bare plant roots. The roots are either suspended in a continuously aerated liquid solution or supported by an inert medium like rockwool or perlite. Commercial growers use this technique in controlled environments to maximize yield per square foot and eliminate soil-borne diseases.
