This is a proven yield and crop booster that you may want to add to your agri- or horticultural tool kit for your 1″ pipes. Please note that for smaller diameter gardening hoses we recommend item RWE-1. Please read here about yield boost with MAGNETIZERS. Hint: magnets have been known to farmers and used by them for a long time. Ours is a special NASA-designed ceramic alloy with precise strength for a given diameter and flow that we harness in a proprietary MONOPOLAR way to get the maximum efficiency of the magnetic fluid treatment.
