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.
: Designed to work superbly in hydroponic environments, both soil-less mixtures and soil grown plants
: Includes pH Test Indicator tube, fill a test-tube halfway with nutrient, add a few drops of pH Test Indicator, and observe the coloration of the liquid in the vial.
: For best results, discard and replace hydroponic solution regularly
