pH Down Acid

pH Down

pH Down (Acid) formulation uses food-grade phosphoric acid to lower the pH to the proper level.

This powdered acid formula is easy to handle and ship. Lightweight in comparison to liquids.

To maximize plant growth, the pH of your nutrients should be slightly acidic.

Experienced growers consider the ideal pH for most crops to fall between 5.5 and 6.5. Users of General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because our formulas are pH buffered.

However, some important exceptions do exist.

Acid content can reach unacceptable levels when nutrient solutions are mixed with poor quality water, or when pH unstable media – such as rock wool or gravel products – are used, or when high plant growth rates destabilize the nutrient mix due to rapid nutrient absorption by the crop.

pH Down (Acid): This acid formulation uses food-grade phosphoric acid to lower the pH to the proper level.

Grower’s Tip:

Most tap water is in the 7.0 to 8.0 range. Hydroponic nutrients are typically acidic and, when mixed in tap water, usually drop the solution into the proper range.

• Acid formulation uses food-grade phosphoric acid
• Add when your nutrient pH is too high in order to lower the pH to the proper level
• Promotes pH stability
