Bluelab pH pen SOIL

Simple manual Bluelab pH Pen SOIL pH and temperature meter for accurate measurements of pH and temperature in soil and substrate. With automatic temperature compensation. Waterproof.

All plants require a balanced supply of nutrients to grow, but plants only have access to nutrients when the pH of your growing medium falls within the correct range.

Contrary to popular belief, all growers need to measure pH, whether you're growing in soil or a solution. This is because pH plays an important role in dissolving your nutrients so they can be absorbed by the plants. If your medium is too alkaline or too acidic, your plants won't be able to absorb all the nutrients they need. Temperature is also important, as it can affect the structure and rate of growth of your plants.
