Cutting Edge Solutions pH Up, 1 qt, case of 12

Potassium Carbonate and Silicate Buffer for Raising Reservoir pH, 1 Qt, Case of 12

Some water sources run naturally acidic, and nutrient concentrates can push pH even lower once they're dissolved into the reservoir, leaving the solution below the range where calcium, magnesium, and phosphorus stay available to the plant. Cutting Edge Solutions pH Up uses potassium carbonate and potassium silicate to raise reservoir pH back into range, adding a small amount of plant-available potassium and silicon along the way.

The 1 qt case of 12 works well for a regular indoor grow room that keeps pH Up on hand for routine reservoir correction between refills.

Key Features & Benefits

• Potassium carbonate and silicate formula — raises pH using potassium carbonate paired with potassium silicate rather than a single alkaline compound.
• No dyes or preservatives added — keeps the reservoir clean by leaving colorants and preservative chemicals out of the formula entirely.
• Highly concentrated — a small volume raises the pH of a full reservoir, so dosing should start conservative and build up gradually.
• Sold in case quantities — cases are sized for operations dosing pH Up often enough to justify buying in volume rather than single bottles.
• Brand-agnostic pH correction — raises pH regardless of which nutrient brand is in the reservoir, so it layers onto CES nutrients or any outside feeding program.

Who Should Use CES pH Up

Growers with naturally acidic water sources, or whose reservoir pH drops once nutrient concentrates are mixed in, who need a concentrated alkaline buffer to bring pH back up into range before feeding.

About Cutting Edge Solutions

Cutting Edge Solutions began in 2001 when founder John Piccirilli, known to growers as “Uncle John,” built a commercial nutrient line out of decades spent cultivating. pH Up and pH Down form the company's Balance family, its dedicated line for reservoir pH management. The company keeps formulation, bottling, and shipping in-house at its production facility in White City, Oregon.

Frequently Asked Questions

What is Cutting Edge Solutions pH Up?

pH Up is a concentrated liquid buffer that uses potassium carbonate and potassium silicate to raise the pH of an acidic nutrient reservoir. The formula skips dyes and preservatives, and it ships in case quantities for growers who dose it on a recurring basis.

How do I use pH Up correctly?

Add pH Up to the reservoir in small increments, stir or circulate the solution, and test pH before adding more. The formula is highly concentrated, so dose conservatively and re-test between additions rather than raising pH all at once.

Does pH Up add nutrients to my reservoir?

Yes, in addition to raising pH, pH Up contributes a small amount of plant-available potassium and silicon from its potassium carbonate and potassium silicate base. Growers dosing at label rates don't need to adjust their base nutrient program to account for it.

When would I need pH Up instead of pH Down?

Use pH Up when the reservoir tests below your target range, which is common with naturally acidic water sources or after nutrient concentrates lower the solution's pH. If the reservoir instead tests above range, pH Down is the correct product to bring it back down.

Is pH Up safe to handle?

pH Up is a concentrated alkaline blend that can burn skin, so gloves and eye protection are recommended when handling or dosing it. Keep the container sealed and out of reach of children or pets between uses, and flush any skin contact under running water right away.
