PH Test Kit
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.
To make soil more acidic, it's easiest to add some peat moss to the mix.
To make your soil more alkaline, add gardening lime.
