General Hydroponics® PRO pH Up - 6 Gallon - Non-Mineral, Non-Corrosive Commercial pH Adjuster - No HazMat Fees

General Hydroponics® PRO pH Up - Next-Generation Non-Mineral pH Adjuster for Commercial Operations

General Hydroponics® PRO pH Up represents a significant advancement over traditional mineral-based pH adjusters. Built on entirely different chemistry from the standard GH pH line, PRO pH Up uses non-mineral-based acids and bases that raises nutrient solution and irrigation water pH without adding unintended nutrient value — unlike phosphoric acid (which adds phosphorus) or potassium hydroxide (which adds potassium). The result is a safer, cleaner, and more logistically convenient pH adjuster for commercial growing operations. Available in commercial 6 Gallon format.

Key Features & Benefits

• Non-mineral chemistry: Does not add phosphorus, potassium, or other nutrients to your solution the way traditional mineral-based pH adjusters do — keeping your nutrient program precise and uncontaminated.
• Zero HMIS safety rating: Carries a zero rating score across all safety categories on the HMIS (Hazardous Materials Identification System) scale — a meaningful safety advantage over conventional pH adjusters.
• Non-corrosive and non-caustic: Significantly safer to handle than phosphoric acid or potassium hydroxide — reducing risk to operators and facility surfaces.
• No HazMat shipping fees: Non-hazmat classification eliminates the costly HazMat surcharges applied to traditional mineral acid and base pH adjusters, reducing procurement costs for commercial buyers.
• Highly concentrated: Formulated for maximum concentration efficiency — a little goes a long way, reducing total product consumption and storage requirements.
• Commercial format — 6 Gallon: The 6 Gallon size suits medium-to-large commercial operations.

Who Should Use This

Designed for commercial greenhouse operators, large-scale hydroponic facilities, and CEA growers who require a high-volume, cost-effective, and safer alternative to traditional mineral-based pH adjusters. The elimination of HazMat shipping costs makes PRO pH Up particularly attractive for facilities ordering in bulk.

Compatibility

Use PRO pH Up alongside PRO pH Down to maintain nutrient solution and irrigation water pH within the optimal 5.5-6.5 range. Compatible with all hydroponic nutrient programs and growing system types.

Frequently Asked Questions

How is PRO pH Up different from standard GH pH Up?

Standard GH pH Up uses potassium hydroxide (which adds potassium to your solution). PRO pH Up uses non-mineral chemistry that adjusts pH without adding nutrient value — and is safer, non-corrosive, and non-caustic with zero HMIS ratings.

Does PRO pH Up affect my nutrient balance?

No — unlike mineral-based adjusters, PRO pH Up does not add phosphorus, potassium, or other nutrients to your solution, keeping your nutrient program precisely dialed in.

Why does the non-HazMat classification matter for commercial buyers?

Traditional mineral pH adjusters (phosphoric acid, potassium hydroxide) typically incur HazMat shipping surcharges. PRO pH Up's non-corrosive, non-caustic classification eliminates these fees — a meaningful cost saving for commercial facilities purchasing in bulk.

Is PRO pH Up safe to handle without special PPE?

PRO pH Up has a zero HMIS rating and is non-corrosive and non-caustic — significantly safer to handle than traditional mineral pH adjusters. Always follow label directions and use standard safe handling practices.
