Meet the family
Introducing new, professional-grade pH adjusters from General Hydroponics. Use Pro pH Up or Pro pH Down to effectively adjust the pH of nutrient solutions or irrigation water. General Hydroponics Pro pH adjusters are highly concentrated and available in commercial sizes.
Our Pro line features completely revolutionized technology versus our traditional, smaller-sized adjusters. New, non-mineral based acids and bases will not add nutrient value like phosphoric acid or potassium hydroxide can. Pro pH Up and Down also carry a triple zero HMIS® score. Plus, their non-corrosive and non-caustic (Pro Up) formulas mean there are no HAZMAT fees to ship like with other adjusters. Use Pro pH Up and Pro pH Down to effectively adjust the pH of nutrient solutions or irrigation water in large-scale operations.
Will not contribute fertilizer
Did you know that traditional mineral acids/bases add nutrients to your solutions? Excess or unbalanced nutrients can often do more harm than good by reacting with other nutrients or limiting uptake.
Pro pH UP and pH Down’s non-mineral formulations will not add extra nutrients, ensuring carefully constructed nutrient recipes are maintained at all stages of growth.
Unique, non-corrosive formulas
General Hydroponics Pro pH Up and pH Down are non-corrosive (Up is also non-caustic) and carry a zero rating for all HMIS categories. They are also not HAZMAT listed like many competitive products, minimizing expensive shipping fees.
3x stronger than GH hobby options
Professional-strength pH adjusters are a must for professional growers, but can be difficult to find in commercial sizes. General Hydroponics Pro pH Up and pH Down are nearly 3x as concentrated as our hobby/retail versions, and are available in convenient sizes for growers of all sizes!
