Black PearlTM is an all natural soil amendment with high level of organic matter and minerals specifically designed to improve plant development by re-mineralizing the soil and improving soil structure. This formula contains soluble and insoluble inputs and is not meant for re-circulating water culture.
Black PearlTM is best applied during soil mixing or transplanting into soil and soilless media. For media mixing, work 25 ml (2 tbsp) per Liter (qt) in to the soil blend. For transplants, dust 45 ml (3 tbsp) directly under the roots and work lightly in to soil. Water thoroughly and then place plant in to transplant hole. Black PearlTM can be used as a top dress, but will be more effective when placed deeper in the Medium/Soil.
