Bat guano, which is renowned as an unparalleled source of available natural phosphorus is combined with langbeinite which is a natural source of potassium, carefully mined from ancient sea beds in the desert of the American Southwest. Aurora Innovations has taken generations of gardening experience and distilled it into a distinctive, easy-to-use formula for the home and professional gardener. HP2 and HPK: Two liquid guano boosters. HP2 is pure phosphorous from liquid bat guano. HPK is phosphorous from bat guano supplemented with potassium from a mineral called langbeinite. We separated these two products because coco, which is often present in good potting soils, has a high cation exchange rate with potassium, meaning the plant takes it up quickly. You don't want to overdo potassium in a coco heavy medium, hence the offering of pure HPK as a separate option. Carefully collected from specific global sources, Roots Organics HPK is minimally processed to preserve all of the benefits and amazing synergistic qualities found in our exceptional ingredients. APPLICATION RATE Soil or Hydroponics Add 1 TBS (15 ml) per gallon. Use during fruiting or flowering.
