Growth Technology pH Down

Growth Technology pH Down – Full Strength 81% Phosphoric Acid

Keep your nutrient pH in check. Growth Technology pH Down is a concentrated 81% phosphoric acid solution designed for reliably lowering the pH of nutrient solutions in hydroponics, coco, and soil. Formulated using food-grade phosphoric acid, it’s the trusted way to bring overly alkaline feeds back into the optimal range for nutrient uptake.

Why Use pH Down?

• Full strength 81% formula: Fast, effective pH reduction with minimal volume required.
• Ensures nutrient uptake: Keeps your solution in the sweet spot for absorption and plant growth.
• Versatile: Works across hydroponics, coco coir, and soil-based grows.
• Food grade phosphoric acid: Premium quality formulation safe for edible crops when used correctly.

How to Use

1. Prepare your nutrient solution as usual and measure the current pH.
2. Add pH Down gradually (a few drops or ml at a time depending on tank size), stirring thoroughly.
3. Re-test after each addition until the target pH is reached.
4. Typical target ranges: 5.5–6.5 for hydro/coco, 6.0–7.0 for soil.

Tip: Always dose slowly. It’s easier to add more than to correct overshooting.

Safety & Handling

• Although not extremely dangerous, pH Down is still a strong acid – handle with care.
• Wear gloves and eye protection when handling concentrated solution.
• Avoid skin or eye contact. If contact occurs, rinse immediately with water.
• Store upright in a cool, dry place away from children and pets.
• Never mix directly with pH Up. Add separately to your solution.
