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. We have a full range of control solutions, essential in the proper management of nutrients in hydroponic systems. We manufacture these products 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 you buy. This is a very dense liquid and should feel much heavier than water.
