Growth Technology ph liquid test kit

Correct pH is vital for the balanced absorption of mineral nutrients in hydroponic cultivation.  The Test Kit provides a cost effective means to read the pH.  Designed to be used in conjunction with pH Up and pH Down to ensure optimum uptake of nutrients.

Growth Technology pH UP contains potassium hydroxide (KOH). This is a very caustic liquid and should be handled with extreme care. Once again our product, at 25%, is stronger than some competing products. Always check the label for best value.

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.
