FAQ & growing tips
Is it as accurate as a digital meter?
It is an indicative method based on color comparison. For a numerical and repeatable reading, a calibrated pH meter remains more suitable.
Why can the color be unclear?
Lighting, sample turbidity, and contamination can affect it. Use a clear sample and compare in good light.
