Product description

The pH Control Kit by General Hydroponics provides everything you need for testing the pH level of the nutrient solution in your hydroponic system. The pH balance is essential for stimulating vigorous plant growth. Vital elements in nutrient solution having pH that is too high (basic) or too low (acidic) cannot be properly absorbed by plants. Incorrect nutrient solution pH can cause slow growth, sickly plants and low yields.
