Fox Farm Cultivation Nation pH Down

Lowers Nutrient Solution pH 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. Cultivation Nation® pH DOWN lowers the pH of nutrient solutions. 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 at a time, testing for pH again after each application. Continue until the desired pH is reached. CAUTION: Only add pH DOWN directly to water or nutrient solution
