BLACK PEARL 10L GROTEK ORGANICS

Grotek’s Black Pearl pioneered biochar in our industry as a means of improving soil quality and enhancing the effects of biology added to substrate mixes and nutrient recipes. The science of biochar has been in the making in the eight years since we first launched Black Pearl. The evidence is clear: when used properly in combination with a nutrient and substrate management program, biochar can have a tremendous impact on soil quality and plant development.
