Diamond Black is a biological nutrient that comes from a new natural source of humic acid, wood.
Made by General Hidroponics and its use is widespread in cannabis growers.
Diamond Black is composed of ligno-humates pure and contains an exceptionally high percentage of active humate in plants. These organic compounds improve the absorption of nutrients, stimulate microbial activity, improve soil structure, increase the retention of nutrients and reduce water use in the landscape.
In addition, Diamond Black can also be used as additive in the preparation of compost.
