General Hydroponics PRO pH Up - 55 Gal - 23.5 x 23.5 x 34-in

Raise Low pH Without Adding Nutrients - 55 Gal Commercial Drum

When a mixed nutrient solution or irrigation water drifts too low in pH, nutrient availability and plant response suffer. PRO pH Up corrects it using non-mineral acids and bases, so the adjustment does not add nutrient value the way phosphoric acid or potassium hydroxide adjusters do. It is also non-corrosive and non-caustic, and it carries a zero rating in every HMIS safety category.

The 55 Gal size suits commercial operations and large hydroponic systems that adjust pH at volume and want one bulk supply. Smaller growers will find a drum this size far more than they need.

Key Features & Benefits

• Non-mineral formula — corrects pH without adding nutrient value to your feed program.
• Non-corrosive and non-caustic — easier to handle than mineral-based adjusters.
• Zero HMIS ratings — a zero score in all safety categories on the HMIS scale.
• Highly concentrated — a small amount goes a long way when you add it gradually.
• Commercial 55 Gal drum — one bulk supply for high-volume feeding.

Who Should Use General Hydroponics PRO pH Up

Commercial cultivation teams and large-scale hydroponic operators who regularly raise the pH of nutrient solutions or irrigation water will get the most from this drum.

Frequently Asked Questions

Q: How do I use PRO pH Up?
A: Adjust after your nutrients are fully mixed. Add pH Up sparingly, stir, test, and repeat until the solution reaches your target range.

Q: Will it add nutrients to my solution?
A: No. It uses non-mineral acids and bases, so it does not add nutrient value like phosphoric acid or potassium hydroxide adjusters.

Q: What does pH Up do?
A: It raises pH when a nutrient solution has become too low. Keeping pH in the target zone supports nutrient availability and plant response.

Q: Is it corrosive or caustic?
A: It is listed as non-corrosive and non-caustic, with a zero HMIS rating in all safety categories. Still review the safety data sheet and follow your site's handling practices.

Q: What does HMIS mean?
A: HMIS is the Hazardous Materials Identification System, a rating scale for health, flammability and physical hazards. A zero score in every category indicates the lowest hazard rating.

Q: Do I need a different product to lower pH?
A: Yes. PRO pH Up only raises pH. The PRO line has a separate pH Down product for lowering it.
