FoxFarm - Cultivation Nation PH Down Quart
Cultivation Nation® pH DOWN lowers the pH of nutrient solutions. An ideal pH range for growing plants is 5.6 – 6.8. Shake well before use.
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.
Only add pH DOWN directly to water or nutrient solution. See product label for detailed precautionary and first aid information.
