pH Up/pH Down
(Bottles sold separately, do not come as a pair)
pH Up - for raising the pH of hydroponic nutrient solutions (Contains Potassium Hydroxide (KOH) 25%)
pH Down - for lowering the pH of hydroponic nutrient solutions (Contains Phosphoric Acid (H3PO4) 81%)
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.
pH UP contains potassium hydroxide (KOH). This is a very caustic liquid and should be handled with extreme care.
