Growth Technology pH Up 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. Plants absorb minerals best between pH 5.5 and pH 6.5 and the best pH for a nutrient solution when growing plants hydroponically are between 5.8 up to 6.2. The concentration is 81%, which is very strong so handle with care. Some other products on the market are considerably weaker so check the concentration before you buy. This is a very dense liquid and should feel much heavier than water.
