Improve soil quality year after year
Black Pearl by Grotek is an "all in one" scientifically designed to improve the soil mix. A set of certified organic substances, including soy enzymes and alfalfa to provide a unique nutritional blend. The product also includes a substance called biochar, which is a durable carbon that greatly stimulates the bacteriological and microbiological development of the soil. The formula has both soluble and insoluble nutrients for long-term release.
Grotek is proud to add Black Pearl to its product range. Black Pearl is a powder that must be pre-mixed with the substrate or sprinkled directly under the root transplant.
