The General Hydroponics GH1522 pH Up Liquid Quart is designed to raise pH in the nutrient solution of a hydroponic system. The solution is made out of potassium hydroxide and potassium carbonate. Nutrient pH solution should be slightly acidic, with the ideal pH for most crops being between 5.5 and 6.5. The GH1522 solution allows gardeners to easily adjust the pH in their nutrient solution by adding a little at a time of the up or down solution.
