Diamond Black

NPK:  0-0-1

General Organics Diamond Black is derived from 100% pure mined Leonardite, a naturally occurring form of carbon drawn from prehistoric peat bogs. 

Part of the new General Organics (GO) line from General Hydroponics, liquid formula Diamond Black provides your plants with the right amount of humic acid to develop strong roots.

It contains a high percentage of plant-active humates which supports beneficial microbial activity in soils and increases micronutrient availability.

Use Diamond Black with any type of garden soils or potting mixes during all phases of plant growth.
