PRODUCT SUMMARY
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.
HP2 liquid seabird guano and phosphate rock is a natural source of organic phosphorous, ideal for use during flowering and fruiting.
