This is a 25% solution of potassium hydroxide, used to raise the pH of nutrient solutions. It is a very basic (alkaline) solution and should be handled with care. (Note – Do not store pH Up with pH Down.)
Different plant species have different requirements, but in general, most plants like a pH range of 5.5 – 6.5. pH Down is added sparingly to nutrient solution to help keep the acidity within this range.
