Pro pH Down – General Hydroponics

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.

pH Up (Liquid) – General Hydroponics

General Hydroponics Pro pH adjusters are based on completely different technology than our traditional smaller sized adjusters offering. New non-mineral based acids and bases will not add nutrient value like the use of phosphoric acid or potassium hydroxide. They are safer to use as well as compared to mineral based adjusters. This is due to having a zero rating score for all safety categories on the HMIS scale as well as being non-corrosive and non-caustic.
