Cutting Edge Solutions® pH Down™ - 32oz - Precision Buffered pH Adjuster for Hydroponic Nutrient Solutions

Precision-Buffered pH Down for Hydroponic Reservoirs, 32oz

A pH adjuster that overshoots on every dose turns a routine reservoir check into a back-and-forth correction cycle. Cutting Edge Solutions pH Down is a precision-buffered acidic liquid engineered to move nutrient solution pH in a controlled, predictable way, so it lowers pH toward the target range without wide swings when used as directed.

This 32oz size is right-sized for growers who adjust pH frequently across drip, DWC, NFT, ebb and flow, and recirculating hydroponic systems.

Key Features & Benefits

• Precision buffering — formulated for accurate, stable pH adjustment without wide swings or overcorrection.
• Lowers solution pH — acidic liquid chemistry moves water and nutrient solution pH to the target range for optimal nutrient availability.
• Nutrient solution compatible — suitable for all grow system types including DWC, NFT, ebb and flow, drip, and recirculating systems.
• Convenient 32oz size — right-sized for small to medium growing operations and frequent pH adjustment.

Who Should Use This

Hydroponic growers, CEA operators, and indoor cultivators who need reliable, consistent pH control to keep nutrient solutions in the 5.5-6.5 range are the direct fit for pH Down. Works alongside pH Up for complete pH management.

Frequently Asked Questions

What does "precision buffering" mean?

Precision buffering means the formula is engineered to shift pH in a controlled, predictable way without wild swings. That makes it easier to dial in and hold the target pH range in the nutrient solution.

How much pH Down should I add?

Always add in small increments, typically around 1 mL per gallon as a starting point, then mix thoroughly and re-test before adding more. The exact amount depends on the source water's buffering capacity and current pH.

What is the ideal pH range for hydroponic systems?

Most hydroponic crops perform well with a nutrient solution pH between 5.5 and 6.5. Staying within that range keeps essential macro and micronutrients available for plant uptake.

Can pH Down be used with all Cutting Edge Solutions nutrients?

Yes, pH Down is designed to work with Cutting Edge Solutions nutrient lines and is compatible with any hydroponic nutrient program. Add it after base nutrients are diluted in the reservoir.
