It's time to get down! Use Cultivation Nation pH Down to lower the pH of your nutrient solution in both soil and hydroponic environments. An ideal pH range for growing plants is 5.6 - 6.8. Take a pH reading of the nutrient solution. Based on your pH reading, adjust the pH by adding small amounts of pH down to a time, testing for pH again after each application. Continue until the desired pH is reached. Only add pH down to water or nutrient solution. Do not use with products that are incompatible with acids, including thiosulfate fertilizers. Comes in 1 pt or 1 qt.
