pH up and pH down
Keep the nutrient solution and growing medium at the “sweet spot” (pH 5.56.5) for optimal nutrient uptake and no nutrient deficiencies.
WHAT MAKES IT WORK?
pH Up and pH Down are buffers composed of a weak base (top) and a weak acid (bottom) designed to correct pH imbalances in hydroponic gardens.
pH Up when pH tests too acidic
pH down when the pH is too alkaline
Small quantities, root and substrate friendly
