PH Down
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.
What pH Down Does

Each plant has its own requirements, but most require a pH of between 5.5 and 6.5. To maintain this pH level, pH Down can be added to the nutrient solution sparingly.
