Essentials LAB pH Down is a concentrated phosphoric acid that can be used to reduce the pH of almost any liquid that it is added. When growing plants in hydroponics or aeroponics, it is necessary to keep the pH of your nutrient solution within a certain range.

Different plant species have different requirements but in general most plants like a pH range of 5.5 – 6.5. pH Down is added sparingly to the nutrient solution to help keep the acidity within this range.
