Growth Technology's Hydroponics PH Up contains 25% Potassium Hydroxide and it is used to adjust and raise the PH level of your nutrient solution, to achieve the ideal PH level for the type of plants you are growing, so they can uptake and obtain all of the nutrients that you supply in the water.
When using aggressive liquids such as PH Up take care to keep it out of reach from children, and gloves and eye protection should also be worn.
How To Use
