Overview

General Hydroponics pH Test Kit

pH Adjusting Solutions. Achieve perfect pH.
To maximize plant growth, the pH level of your nutrients should be slightly acidic. Experienced growers consider the ideal pH for most crops to fall between 5.5 and 6.5. Users of General Hydroponics nutrient products generally do not experience problems maintaining the proper pH range because our formulas are pH buffered. However, some important exceptions do exist. pH can acidify to an unacceptable level when nutrient solutions are used with poor-quality water, or pH-unstable media, such as rockwool. High growth rates can also destabilize pH.

pH Test Kit

The General Hydroponics pH Test Indicator can help you maintain an ideal pH level (which is between 5.5 and 6.5). This can be achieved by monitoring your pH using the super-concentrated drops found with the test indicator. Based on the test results, pH Up or pH down (available separately) can be added to adjust the pH as needed. The General Hydroponics pH Test Indicator works across a wide pH spectrum (pH 4.0 – 8.5). Kit includes a sampling tube, reagent, and color comparison for easy and reliable testing.

PH TEST PROCEDURE:

General Hydroponics pH Test Kits make pH testing easy. Simply fill a test-tube halfway with nutrients, add a few drops of pH Test Indicator, and observe the coloration of the liquid in the test vial. Many experienced growers prefer our pH Test Kit to expensive electronic meters because of its reliability and ease of use, which are important factors when the health of a valuable crop is at stake. Use 3 drops per 5 ml of solution.

  1. Fill the test vial ½ full with the solution to be tested.
  2. Add 3 – 5 drops of pH test indicator to the vial.
  3. Tap the side of the test vial to mix the contents.
  4. Observe the color in the test vial.

Add pH DOWN (Acid) to lower pH. Add pH UP (Base) to raise pH.

*The best pH is between 5.5 and 6.5.
