Roots Organics HPK 0-4-3, 1 qt

This liquid organic PK bloom booster is extracted from our unique natural sources of phosphorus and potassium. Bat guano, recognized as an organic source of phosphorus, is combined with langbeinite, a natural source of potassium extracted from ancient seabeds in the Southwest United States. HPK is minimally processed to retain all the benefits and synergistic qualities of its ingredients. It effectively improves flower quality and is suitable for use in soil and hydroponics.
