The General Hydroponics 4-Piece pH Control Kit provides everything needed to manually test, raise, and lower the pH of hydroponic nutrient solutions. It combines a wide-range liquid pH indicator with General Hydroponics pH Up and pH Down, making it easy to monitor and correct nutrient-solution pH without a digital meter.

The indicator solution covers a broad pH range from 4.0 to 8.5. Many hydroponic crops are commonly grown within a nutrient-solution range of approximately 5.5 to 6.5, although the correct target depends on the crop, growing medium, and feeding program.
