pH Test Kit

To maximize plant growth, the pH level of your growing media should be slightly acidic. The ideal pH for most crops falls between 5.5 and 6.5.

General Hydroponics PH Test Kit 1 OZ make pH testing easy. Fill a test-tube halfway with water/soil/nutrient, add 3-5 drops of pH Test Indicator, and observe the colour of the liquid in the test vial. 

At House of Monstera, we purchased multiple soil test kits when learning about soil pH and nutrient availability. Comparing the results between them showed that they each showed the same results (including this one). This test kit is marketed towards hydroponic growing, but works just as well when used to test growing media. This kit comes with a vial and a large amount of litmus fluid.

How to Use:

It is easiest to compare the test vial to the pH range in bright light.

To test the pH of tap water, rain water or spring water, fill vial halfway and add 3-5 drops of testing fluid, comparing the colour of the vial to the indicator on the dropper bottle.

To test the pH of your grow media, fill vial halfway with soil, add distilled water (neutral pH), then add 3-5 drops of testing liquid and shake. Allow soil to settle and compare colour with the indicator on the dropper bottle.

If you water from the tap, repeat the soil test without distilled water, replacing it with tap water.
