| Our pH Test Kit is perfect for easy pH tests. Simply fill the test-tube halfway with nutrient, add a few drops of pH Test Indicator and observe the resulting color inthe test vial. Red means the pH is too low, blue means the pH is too high (basic or alkaline), yellow to yellow-green is ideal. Very reliable and simple to use, many experienced growers prefer our pH Test Kit over expensive electronic meters because our kit is simply more reliable - important when a valuable crop may be at risk |
