Roots Organics HPK

HPK by Roots Organics

Roots Organics HPK liquid bloom booster features a combination of seabird guano, an unparalleled source of available natural phosphorus, and langbeinite, a natural source of potassium that is carefully mined from ancient sea beds in the deserts 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. Roots Organics HPK is minimally processed to preserve all the benefits and amazing synergistic qualities found in our exceptional ingredients.

HP and HPK:

HP² and HPK: Our two liquid guano boosters. HP² is pure phosphorous from liquid seabird guano. HPK is phosphorous from seabird 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 our offering of pure HPK as a separate option.
