Black Pearl™ was the first product in our new Grotek™ Organics line! Grotek™ was the first to bring engineered charcoal to our industry in 2009 as a means to improve soil quality, plant growth, and to stimulate soil biology. Black Pearl™ is more than just high-quality charcoal. It is a super mineralized with organic inputs like volcanic and sedimentary rock dust, natural chelates, and kelp extract. The harmony between ingredients provides a dramatic boost to crops when added to any nutrient program. Remember that not all charcoal is the same. At Grotek™ we use virgin wood fibre from sustainably managed forests charred in an engineered pyrolysis process. It is considered a Class 1 product by the IBI standards with a surface area over 700m2/g. Peak efficacy achieved when used to stimulate microbial products like RootMax™.

Avoid contact with eyes, skin, and clothing. Wash hands after use. Store in a cool, dark location with the lid secured between uses. Black Pearl™ is best applied during soil mixing or transplanting into soil and soilless media. For media mixing, work 25 ml (2 tbsp) per Liter (qt) in to the soil blend. For transplants, dust 45 ml (3 tbsp) directly under the roots and work lightly in to soil. Water thoroughly and then place plant in to transplant hole. Black Pearl™ can be used as a top dress, but will be more effective when placed deeper in the Medium/Soil.
