General Hydroponics® pH Control Kit

Makes pH testing easy. Simply fill the test-vial halfway with nutrient solution from your hydroponic system, add a few drops of pH Test Indicator, and observe the color of the liquid in the test vial verses the colors on the included chart.

To maximize plant growth, the pH level of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most hydroponic crops to fall between 5.2 and 6.4.

pH Up: Add a little at a time if your nutrient pH is too low in order to raise the pH to the proper level.

pH Down: Add a little at a time if your nutrient pH is too high in order to lower the pH to the proper level.

Kit contains 8 oz pH UP, 8 oz pH DOWN, 1 oz indicator solution, vial, and color chart.
