Hydroponic Concepts™ pH-adjustors for adjusting the pH of a nutrient solution. For better growing results, your nutrient mix must measure a pH of between 5.5 and 6.5, the ideal being 6.

Use Hydroponic Concepts™ pH-adjustors in combination with a pH meter or pH test sticks. pH UP contains citric acid monohydrate and pH DOWN contains caustic soda flakes.
