Growth Technology pH Down 30% – Phosphoric Acid pH Adjuster for Hydroponics (1L & 5L)

Maintaining the correct pH is one of the most important factors in any hydroponic system. The ideal pH range for most hydroponic setups is between 5.6 and 6.2. Outside this range, nutrient uptake is impaired and plant health deteriorates rapidly.

Growth Technology pH Down 30% is a phosphoric acid solution used to lower the pH of nutrient solutions quickly and accurately. A small amount goes a long way, making it a cost-effective choice for both small and large systems.

Key Features

• 30% phosphoric acid solution for effective pH reduction
• Suitable for all hydroponic and soil-based growing systems
• Fast-acting and easy to dose
• Available in 1L and 5L sizes

How to Use

• Test your nutrient solution pH using a pH meter or test kit
• Add pH Down in small increments, mixing thoroughly after each addition
• Retest and adjust until the desired pH is reached (5.6–6.2 for most crops)
• Handle with care — do not store alongside pH Up
