General Hydroponics pH Control Kit contains 8 oz pH UP, 8 oz pH DOWN, 1 oz indicator and vial.
Testing your solution takes just a few moments. Start by filling the test tube half full with your mixed nutrient solution. Then, add 3-5 drops of the pH test indicator to the vial and shake it - this will alter the color of your solution. You can compare the color in your vial to the pH color chart to determine if pH is too low, too high, or just right.
pH Color Chart
- Yellow to Yellowish-Green - Indicates the ideal pH range for plant growth (5.5-6.5).
- Orange or Red - Indicates the pH is too low (below 5.5), add pH UP (Base) to raise nutrient pH.
-
Blue-Green or Blue - Indicates the pH is too high (above 6.5), add pH DOWN (Acid) to lower nutrient pH.
Repeat to verify the nutrient pH is now within the correct range (5.5 - 6.5.)
