pH Testing and Adjusting Kit

The Complete pH Testing and Adjusting Kit comes with a pH Test Kit and Crystal pH Up and pH Down. Drops are reliable and simple to use to give an accurate pH reading of your fertilizer solution or reservoir. Fill the test tube about halfway with the solution you are testing, then add a few drops of the pH test indicator and observe the resulting color. Red (acidic) indicates that the pH is too low, blue (alkaline) indicates that the pH is too high, a yellow to a yellow-green indicates an ideal pH. Add the Adjusting Crystals as needed to lower or raise pH.”,”highlights”:[“Provides accurate pH reading of fertilizer solution or reservoir”,”Reliable and easy to use with clear indication of results”,”Just add a few drops of pH indicator (included) and observe color”
