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

pH Up — Concentrated Alkaline pH Adjustment Buffer for Hydroponic Reservoirs, 1 qt (Case of 12)

Water that is too acidic can drive the nutrient solution pH below the optimal range for hydroponic absorption, locking out calcium, magnesium, and phosphorus even when they are present in sufficient quantities. Raising pH to the target range unlocks nutrient availability and restores the chemistry of the root zone to a productive state. A concentrated alkaline buffer makes it possible to raise pH precisely without adding large volumes of dilute solution to the reservoir.

Cutting Edge Solutions pH Up is a concentrated alkaline buffer formulated to raise the pH of water and nutrient solutions. Like pH Down, it is highly concentrated and should be added in small increments with testing between additions to avoid overshooting the target pH. pH Up contains no artificial dyes and was developed in conjunction with CES nutrients. Sold in 1 qt (Case of 12).

Key Features & Benefits

• Concentrated alkaline pH buffer — highly concentrated alkaline buffer raises water and nutrient solution pH; a small volume adjusts a large reservoir.
• Add in small increments — highly concentrated — add conservatively in small increments, stir well, and test pH after each addition to avoid overshooting the target.
• No artificial dyes — formulated without artificial dyes or colorants.
• Developed for CES nutrient programs — formulated in conjunction with Cutting Edge Solutions base nutrients for seamless compatibility.
• Sold by the case — available as 1 qt (Case of 12) for operations that go through pH adjustment solution regularly.

Who Should Use CES pH Up

Hydroponic and indoor growers who need to raise the pH of their water or nutrient solution and want a concentrated, dye-free alkaline buffer that is compatible with CES nutrient programs.

How to Use pH Up

Add pH Up to the nutrient reservoir or water source in small increments. After each addition, stir or agitate the solution thoroughly and test pH with a calibrated pH meter or test solution. Continue adding in small amounts and testing until the desired pH is reached. Because pH Up is highly concentrated, the required dosage varies with the buffering capacity of the solution — start conservatively and adjust from there. Always adjust pH after all nutrients and additives have been mixed.

Frequently Asked Questions

What is Cutting Edge Solutions pH Up?

pH Up is a concentrated alkaline buffer that raises the pH of water and nutrient solutions. It is formulated without artificial dyes and was developed in conjunction with CES nutrients. It is sold in cases for regular commercial use.

When would I need to use pH Up?

pH Up is used when the pH of your water or nutrient solution is below the target range for your crop. This can happen with naturally acidic water sources, after mixing acidic nutrient concentrates, or when growing in systems where the pH drifts downward. Raise pH Up to the target range before feeding.

How concentrated is CES pH Up?

CES pH Up is highly concentrated. Always add in small increments, stir thoroughly, and test pH before adding more. Overshooting the target pH requires correction with pH Down, so it is more efficient to approach the target gradually.

What pH range should I target in hydroponics?

For most hydroponic crops, a pH range of 5.5 to 6.5 is recommended, with many growers targeting 5.8 to 6.2 as the optimal window for broad nutrient availability. Consult the CES feeding guide for recommended pH ranges with CES nutrients.

Can I use pH Up and pH Down together?

Yes — pH Up and pH Down work together as a pair to allow precise pH management in either direction. Adjust the pH of your reservoir after all nutrients and additives have been dissolved, testing between each addition of pH adjustment solution.
