Blueline Hydroponic Growing Medium and Soil pH Measuring Pen.

Potential hydrogen within the correct range plays an important role in leaving nutrients soluble so they can be absorbed by plants. 
Soil acts as a natural buffer, pH fluctuations are mitigated. A pH meter is used by growers for land agronomy to increase growing parameter accuracy for specialized cultures, research, greater yields and to successfully propagated endangered plant species.
In hydroponic cultivations, if the solution content or the medium itself is too acidic or alkaline, plants will not be able to get all the nutrients they need to grow and flourish.
Ideal temperature ranges for every plant variety is fundamental to successful agriculture.
