pH Test Kit

General Hydroponics pH Test Kits make pH testing easy.

Fill a test-tube halfway with nutrient, add a few drops of pH Test Indicator, and observe the coloration of the liquid in the test vial. Many experienced growers prefer our pH Test Kit to expensive electronic meters because it is reliable and easy of use. 

The pH test indicator is perfect for easy pH level testing, covering a wide range, from 4.0 to 8.5.

Simply fill the test-tube supplied halfway with nutrient solution, add 3 drops of pH Test Indicator, shake and observe the resulting colour.

Compare with the colour chart to check your pH level.

Very reliable, simple to use and cheap, the pH test kit advantageously replaces the expensive digital pH meters.
