PRODUCT SUMMARY
HP2 and HPK: Our two liquid bloom boosters. HP2 is pure phosphorous from liquid phos rock. HPK is phosphorous from phos rock 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.
AVAILABLE IN 265GAL, 55GAL, 15GAL, 5GAL, 2.5GAL, 1GAL, 1QT
