Bluelab Conductivity Pen Lighting Add a pH up adjusterWhy measure conductivity and temperature? Understanding plant health fundamentals All plants need access to the right amount of food (nutrients) so that they can grow and thrive. Over or under feeding your plants can result in the waste of expensive nutrient resources. The easiest way to keep track of the amount of nutrients in your solution is to regularly measure conductivity, which refers to the total ionic content (dissolved salts) in a solution.
