General Hydroponics PRO pH Up - 6 Gal

Correct Low Nutrient pH with a Bulk Supply - 6 Gal

When nutrient solution pH drops too low, plants take up nutrients less effectively. This pH adjuster raises the pH of a mixed solution in small, controlled steps, so you can bring the reservoir back into your target range and keep feeding conditions stable.

The 6 Gal jug suits growers who adjust reservoirs regularly, such as commercial rooms and serious indoor growers running several systems. Hobbyists with a single small reservoir may find it more than they need.

Key Features & Benefits

• Raises low pH — corrects nutrient solution that has drifted below your target.
• Stepwise adjustment — small additions let you approach the target without overshooting.
• Works across programs — supports liquid-feed management in hydroponic and other nutrient programs.
• Bulk jug — a 6 Gal container reduces how often you reorder.

Who Should Use General Hydroponics PRO pH Up

Growers who mix nutrient solutions and need a reliable way to raise pH. It fits commercial facilities and experienced indoor growers who test their reservoirs routinely.

Frequently Asked Questions

Q: When should I add pH Up?
A: Add it after your nutrients are fully mixed, because nutrients change the solution's pH. Adjusting before mixing means you will likely have to correct again.

Q: How do I use it?
A: Add a small amount, stir, and test the solution. Repeat until the reading reaches your desired range.

Q: Why does pH matter?
A: pH affects how available nutrients are to plants and how plants respond to feeding. Keeping it in the target zone helps your feeding program work as intended.

Q: Why add it sparingly?
A: The amount needed varies with your water and nutrients, and a small excess can push pH past your target. Stepwise additions with testing in between keep control in your hands.

Q: Is it safe to handle?
A: Treat it with care. The manufacturer's safety data sheet carries hazard warnings, so read it and follow its handling and storage guidance. Keep it away from children.
