Bluelab pH pen SOIL

All plants need a balanced diet of nutrients (food) in order to grow. However, plants only have access to nutrients if the pH (potential hydrogen) of your growing medium falls within the correct range.

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