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. Black Pearl is high in organic matter, most of which comes from charcoal based carbon, a long lasting soil builder. This product should be premixed in medium or dusted directly under the transplant rootball.
Directions for use:
Black Pearl™ is best applied by mixing it into soil or soilless media rather than as a top dress. This product is not water soluble and should not be used in re-circulating hydroponic systems.
