General Hydroponics pH Up Liquid 1 Quart(s)

General Hydroponics® pH Up is a base solution formulated with potassium hydroxide and potassium carbonate to raise pH to the proper level. pH control is essential for vigorous plant growth. Nutrient solution pH that is too high (basic), or too low (acidic), cannot be properly absorbed by plant roots. Incorrect nutrient solution pH can cause slow growth, sickly plants, and low yields. Our formulas are pH buffered to help growers maintain the optimal pH range. We recommend using pH Up sparingly. Add to your nutrient solution a little at a time, then test the pH. Repeat application, then test, until desired pH is achieved. The quantity necessary for pH adjustment will vary depending on the strength of the nutrient and the purity of the water used to mix the nutrient. The recommended pH for most plants is 5.5 to 6.5. Use General Hydroponics® pH Test Indicator (sold seperately) for testing nutrient pH.
