Gh Pro Ph

Use Pro pH Down to lower the pH value of your irrigation water or nutrient solution. Pro pH Down will NOT contribute phosphorus, nitrogen or sulfate like most pH Down products. When you’re growing professionally, only Pro pH adjusters will do. At nearly 3x the concentration of our retail adjusters, Pro pH Up and Down deliver more power per pint to make balancing nutrient ratios in hundreds of plants more efficient than ever. It’s possible thanks to a unique, non-mineral formulation designed specifically for commercial facilities, and sized for them too. Get Pro pH Up and pH Down in 2.5 gallon, 6 gallon and 55 gallon bottles.
