pH Up 8 oz - GH

Acid content can reach unacceptable levels when nutrient solutions are mixed with poor quality water, or pH unstable media ? such as rock wool and gravel products ? are used, and when high plant growth rates destabilize the nutrient mix due to rapid nutrient absorption by the crop. pH Up: Base formulated using Potassium Hydroxide and Potassium Carbonate. Add a little at a time if your nutrient pH is too low in order to raise the pH to the proper level.
