Roots Organics HPK liquid bloom booster is a specially extracted natural source of phosphorus and potassium.

DERIVED FROM
100% Natural Seabird Guano, Bat Guano and Langbeinite

Roots Organics HPK liquid bloom booster features a combination of bat 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.

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.

Beautiful, but very heavy.
Size: Twin(60" X 80"), Color: Tie Dye Brown
Beautiful and incredibly soft. Label states to wash in cold on gentle, low heat dryer. No dry cleaning. I haven't washed it yet, will update when I do. Of note, it is very heavy for it's size. I purchased the twin size to use as a throw. I don't like any throw size, as it seems they're never long or wide enough for stretching out on the sofa or curling up in a chair to read. It is nice and warm, but not suffocating.
