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

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

Maintaining the correct pH in a hydroponic nutrient solution is fundamental to nutrient availability. Most nutrients are absorbed most efficiently within a specific pH range — typically 5.5 to 6.5 for hydroponic systems — and even small deviations outside this range can lock out critical elements regardless of their concentration in the reservoir. A reliable, concentrated pH adjustment solution makes it straightforward to dial in and hold pH through regular monitoring and correction.

Cutting Edge Solutions pH Down is a concentrated acidic buffer formulated to lower the pH of water and nutrient solutions. It is highly concentrated — a little goes a long way — so it should be added in small increments, with the solution stirred and tested between each addition until the target pH is reached. pH Down contains no artificial dyes. It was developed in conjunction with CES nutrients. Sold in 1 qt (Case of 12).

Key Features & Benefits

• Concentrated acidic pH buffer — highly concentrated acidic buffer lowers 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 Down

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

How to Use pH Down

Add pH Down 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 Down is highly concentrated, the required dosage varies with the nutrient strength of the solution and the starting pH of the water source — start conservatively and adjust from there.

Frequently Asked Questions

What is Cutting Edge Solutions pH Down?

pH Down is a concentrated acidic buffer that lowers 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.

How concentrated is CES pH Down?

CES pH Down is highly concentrated — a small volume is sufficient to lower the pH of a large reservoir. Always add in small increments, stir thoroughly, and test pH before adding more. Overshooting the target pH is easy with a concentrated product; adjust gradually and re-test.

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. The exact target may vary by crop and nutrient program — consult the CES feeding guide for recommended pH ranges with CES nutrients.

How much pH Down do I need to add?

The amount required varies with the starting pH of your water source and the buffering capacity of your nutrient solution. Hard water with high alkalinity will require more pH Down to achieve the same drop as soft water. Start with a small amount, stir, test, and add more as needed.

Can I use pH Down with other CES nutrients and additives?

Yes — CES pH Down is formulated for use with CES nutrient programs. Always add pH Down to the nutrient solution after all nutrients and additives have been mixed, as the final pH may shift slightly as nutrients are dissolved. Test and adjust pH last, before measuring EC or feeding plants.
