Black Pearl™ is a unique organic product that blends a variety of renewable elements to provide soil nutrients and other soil-building components. High in organic matter, most of which comes from charcoal based carbon, it is a long-lasting soil builder.

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.

Reconditioning medium: Apply 4 g (1 tsp) per 4 L (1 gal) of media and mix well. On a larger scale apply 28 g (7 tsp) per 28 L (1ft3). This product is intended for a single application prior to planting.
Charging new medium: Apply 4 g (1 tsp) per 4 L (1 gal) of media and mix well. On a larger scale apply 28 g (7 tsp) per 28 L (1ft3). This product is intended for a single application prior to planting.
