The Neptune Hydroponics reactive pH meter is the simplest model we have at Growlet.
How is the reactive pH meter used?
- Fill the bottle 1/2 full with the water to be tested.
- Add 3 drops of Indicator liquid, cap the bottle and shake.
- Compare the color of the mixture with the attached chromatic scale.
- Correct if necessary with pH + or pH-.
Growlet tip:
In this case, do not add the fertilizer before analyzing the pH, as it will stain the water and make it difficult to recognize the final color after adding the reagent.
