What Is Growth Technology pH Down?

Growth Technology pH down is a 30% concentration of Orthophosphoric acid (H3PO4). It works to acidify any solution it's added to (bringing the pH of the solution down).


Garden tip: pH down is a very strong acid, it needs to be handled with care.


CAUTION: Always add the acid to water to avoid splashing and potential acid burns.

Use pH down to Maintain Your Nutrient Solution In The Best pH Range For Plants (5.5 – 6.5 pH)

Plants in any hydroponic system can only uptake nutrients within the range of 5.5 – 6 pH. If pH levels fluctuate outside of this range, certain nutrients get locked out. This leads to signs of a nutrient deficiency, even if there is a high EC; with plenty of nutrients available in the solution.


Garden tip: For optimal results, manage the nutrient Solution's pH.

About Growth Technology

  • Bottled in black and red – the internationally accepted packaging colours for aggressive liquids.
  • Full compliance with all health and safety regulations.

How Do I Use Growth Technology pH down

A pH meter is essential for maintaining constant pH levels. To ensure healthy growth, check the pH of the nutrient solution at regular intervals and when changing the reservoir.


Garden tip: If pH levels are too low, pH up should be added. If pH is too high, pH down should be added.


When managing pH, only a small dose should be added at a time, stir the reservoir and then test the pH again. If more amendments are required, a small amount should be added each time due to the strength of the solution.

Health & Safety Using pH down

pH down is a 30% phosphoric acid solution and requires safe and careful handling, including the following:


  • Always wear gloves and eye protection when handling aggressive liquids
  • Always store in locked cupboards
  • Keep away from children
  • pH up and pH down should be diluted before use (please see the link on the side of this page for instructions on Handling Aggressive Liquids).
