pH DOWN

pH control is essential in a hydroponic system

Plants in hydroponic systems function best with a nutrient solution pH of between 5.8 up to 6.2.

Growth Technology has a full range of control solutions, essential for the proper management of nutrients in hydroponic systems. These products are manufactured using the purest and most concentrated sources available.

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

Growth Technology pH DOWN contains orthophosphoric acid (H3PO4). The concentration is 81%, which is very strong so handle with care. Some other products on the market are considerably weaker, so check the concentration before buying. This is a very dense liquid and should feel much heavier than water.

Health & Safety:

This liquid needs safe and careful handling:

  • 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 Instruction on Handling Aggressive Liquids.
