GH pH Up - qt
For plants to grow their best it's important that the nutrient pH be slightly acidic - the range of 5.5 to 6.5 is considered ideal for most crops. The General Hydroponics pH Up (Base) is formulated using Potassium Hydroxide and Potassium Carbonate which are both pure plant nutrients. Add a little at a time if your nutrient pH is too low, and this will raise the pH to within range.
