General Hydroponics pH Control Kit

General Hydroponics pH Control Kit


Kit includes; 1 ounce of pH indicator solution, test vial, dropper, 8 ounces of pH down and 8 ounces of pH up.

Contains Ph Up (add a little at a time when your nutrient pH is too low in order to raise the pH to the proper level), Ph Down (uses food grade Phosphoric acid to lower the pH to the proper level), and Ph Test Indicator (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).

Fill test vial halfway with nutrient solution. Add 3-5 drops of pH test indicator and tap vial to mix contents. Compare color in vial to pH color chart to determine nutrient pH.

Yellow to yellowish-green indicates the ideal pH range for plant growth (5.5 to 6.5)

If the test indicates any orange or red -- the pH is too low (below 5.5), add pH UP (Base) to raise nutrient pH.

If the test indicates any blue-green or blue -- the pH is too high (above 6.5), add pH DOWN (Acid) to lower nutrient pH.

Repeat test to verify that the pH is now within correct range (5.5 - 6.5).
