Growth Technology pH Down – 30% Phosphoric Acid Concentrate - 1L

Growth Technology pH Down 30% is a highly concentrated phosphoric acid solution (30%) used to safely and effectively lower the pH of nutrient solutions in hydroponic, soil, or coco systems—handle with care.

Product Description

Growth Technology pH Down 30% is a potent acid solution formulated to quickly and precisely lower the pH of nutrient solutions. With a 30% concentration of phosphoric acid, it is highly effective at bringing nutrient water into the optimal pH range (typically 5.5–6.5) required for maximum nutrient uptake. Its strength allows for minimal dosing for maximum impact on pH levels.

Always add pH Down after all nutrients and additives have been mixed into your reservoir, due to its strong concentration, and follow a cautious dosing method to avoid over-correction or burns (chemical and plant damage).

Key Features

• 30% phosphoric acid formulation—ultra-concentrated for efficient pH reduction

• Minimal dosage required—typically 0.25–0.5 mL per 10 L as a starting guideline

• Highly effective and stable acid—ensures long-lasting pH maintenance in recirculating systems

• Caution-certified packaging—must be handled with extreme care using appropriate PPE (gloves, goggles)

How to Use

1. Test your nutrient solution’s pH before adjustment.

2. Add pH Down in small increments (e.g. 0.25–0.5 mL per 10 L) after mixing all other nutrients.

3. Stir well and re-test the pH, repeating if necessary until reaching the desired level.

4. Continue carefully—this is a strong acid and overuse may damage plants or cause chemical burns.

5. Always wear gloves and eye protection; store securely out of reach.
