The Bluelab Soil pH tester is a digital meter that can be used on both soil and hydroponic mediums. It can even be used to test water pH.

Why should I check pH with a Bluelab meter?
Most soils have a natural buffer for nutrients and pH, but when it goes wrong, it goes wrong really fast. Yellow leaves, stunted growth, slow growth, are all signs that the plant is not getting the nutrients they need from the soil. This is often caused by pH 'lock out’.

pH Lock Out is a situation where the plant loses the ability to absorb specific nutrient elements because the pH value is too far out. A wrong pH needs to be dealt with quickly, so the Bluelab Soil pH Meter is exactly what you need to find out how with any media.
