SECTION: Tools and Supplies,
A good cheap pH test is really handy, especially in fairly new gardens, where inevitably there is a lot of change. Easy to use, clear results - simply 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. Use 3 drops per 5mL of solution. One fl. oz. bottle
