BLACK PEARL™ - SOIL BUILDER -

Black Pearl™ was the first product in our new Grotek™ Green 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 super mineralized with plant and mineral derived 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 is achieved when used to stimulate microbial products suchas Synergy™.

Application Rate: 900ml mixes into 36L of growing media.
For media mixing, work 2 tbsp (25 ml) per Quart (1 L) into the soil blend.
For transplants, dust 3 tbsp (45 ml) directly under the roots and work lightly into soil. Water thoroughly and then place plant into transplant hole.
Black Pearl™ can be used as a top dress, but will be more effective when incorporated into the medium/soil.
This formula contains soluble and insoluble inputs and is not meant for re-circulating water culture.
