Grotek - Black Pearll Brochure
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.
