Formulated with botanical extracts and natural minerals for performance and purity! Clean, pure and healthy!

Diamond Black - Liquid Humic Acids

Diamond Black is derived from 100% pure mined Leonardite, a naturally occurring form of carbon drawn from prehistoric peat bogs. Diamond Black contains an exceptionally high percentage of plant-active humates. These organic compounds improve nutrient absorption, stimulate microbial activity, promote soil structure, increase nutrient retention and reduce water usage in the landscape.

Diamond Black can be added to all kinds of garden soils and potting mixes, and used with a wide variety of plants during all phases of growth. Additionally, Diamond Black can also be utilized as an additive for making compost. Use Diamond Black with any garden soil, potting mix, or other soil-based media.

VGANIC - Contains no animal derived ingredients. Pure nutrients formulated with botanical extracts and natural minerals for performance and purity. Clean, pure and healthy.
