HUMIBOOSTA™ is formulated using a blend of Humic and Fulvic acids to improve nutrient solubility thus enabling maximum nutrient availability. They are selected and derived from various natural deposits and processed sources. Additional macro nutrient forms of these organic acids ensure that background nutrient levels are replenished throughout all stages of plant development. Humic and Fulvic acid are known for their ability to bind to nutrients making them more absorbable. HUMIBOOSTA is suitable for all systems and can be used through all stages of plant growth and flower and fruit development.
