Keep the nutrient solution and the growing medium in the “sweet spot” (pH 5.5‒6.5) for optimal nutrient uptake and no nutrient deficiencies.
When the pH of the nutrient solution is too low or too high, certain elements (e.g., iron or manganese) could be wholly or partially “locked out”
pH Up and Down are buffers composed of a weak base (up) and weak acid (down) designed to correct pH imbalances in hydroponic gardens.
- pH Up when the pH tests too acidic
- pH Down when the pH tests too alkaline
- Small, root-and-substrate-friendly quantities
- pH 5.8–6.3 – the ideal range for high-value plants grown in hydroponic gardens
