Grotek is proud to add Black Pearl™ to our product line up. This organic product is a blended powder that aims to build soil by replenishing nutrients. Black Pearl™ contains Nitrogen, Phosphorous and Potassium to support vegetative growth, larger root systems, vigorous blooming and increased drought tolerance. This product also includes the benefits of a technical grade soluble kelp extract. Kelp has been used for centuries by coastal farmers to enhance soil nutrition. Black Pearl™ is high in organic matter, most of which comes from charcoal based carbon, a long lasting soil builder. This product is designed as both a soil improver and a plant nutrient.
