General Hydroponics pH Control Kit

The ph balance is essential for stimulating vigorous plant growth. Incorrect nutrient solution pH can cause slow growth, sickly plants and low yields. The ph control kit by general Hydroponics provides everything you need for testing the pH level of the nutrient solution in your hydroponic system. Using either ph up or ph down, adjust the nutrient solution in your reservoir by adding small amounts of UP or DOWN with frequent re-testing to achieve the desired pH range typically 5.

5 to 6. 5 for hydroponics. For best results, discard and replace hydroponic solution regularly. The kit contains ph up potassium hydroxide, pH Test Indicator, pH DOWN phosphoric acid, and a test vial.
