General Hydroponics®, pH Down, Liquid, Acid, Premium Buffering For pH Stability (1 Quart)

Fine-tune hydroponic nutrient solution pH with General Hydroponics pH Down

General Hydroponics® pH Down is a liquid acid formula for gradually lowering and stabilizing pH in hydroponic nutrient solutions. It is easy to measure and add while you monitor your reservoir, helping keep the solution in the range your plants and growing medium require.

Why growers choose it

• Liquid pH adjuster for hydroponic nutrient solutions
• Helps lower pH when a solution tests too high
• Easy to measure, mix, and adjust gradually
• 1-quart size for hobby, home, and small-to-mid-size gardens
• Works alongside a complete General Hydroponics feeding program

How to use

1. Test your mixed nutrient solution before adjusting.
2. Add a small amount of pH Down while stirring.
3. Wait for the solution to mix, then retest and repeat carefully as needed.

Good to know: Many hydroponic growers target approximately pH 5.5–6.5, but the correct range depends on your crop and medium. Always follow the product label and handle liquid acid safely.
