The pH Drop Tester by GHE is an affordable and practical pH tester that comes with reagent liquid so that you can easily test your water before mixing the nutrients in by simply using a couple of drops of reagent. If the color is between light orange and light green, the water is within the right pH level.

The most important thing to keep in mind is that you need to measure the pH of the water on its own, with no nutrients at all as this can negatively affect the results.

If it’s between dark green and blue, you’ll need to use a product such as pH down so that your plants can properly absorb the micro-elements in your nutrient solution.

If it’s between orange and red, you’ll need to adjust acidity with pH up so that your plants can absorb all nutrients from your water.

With this simple pH tester you can easily water your plants with the right pH, allowing them to absorb the maximum amount of nutrients possible, growing strong and healthy.

In order to get even better results, you might want to adjust the EC too.
