Why measure conductivity? - Optimise nutrient levels
All plants need access to the correct amount of food (nutrients) so that they can grow and flourish. Over- or under-feeding your plants can result in the waste of expensive nutrient resources and plant health issues.
The simplest way to keep track of the amount of nutrients in your solution is to measure conductivity, which refers to the total ionic content (dissolved salts) in a solution. From a scientific perspective, when nutrients are added, this creates the potential for electricity to move through a solution, increasing the electrical conductivity.
By measuring and adjusting nutrient levels, you’ll ensure that your plants are getting the macro- and micro-nutrients they need for superior plant health.
Team up with the Bluelab pH Pen to cover all the plant health fundamentals
As a grower, your solution’s pH (potential Hydrogen) is the most critical fundamental measurement to track. It plays a crucial role in making nutrients soluble in water so that they can be accessed by your plants.
The Bluelab pH Pen is an affordable and compact handheld solution for measuring pH and temperature on the go.
When you combine this pen with Bluelab’s Commercial Truncheon Nutrient Meter, you’ll be able to measure conductivity, temperature and pH, which not only enables you to actively manage your nutrient levels but also ensures that your plants have access to the food they need. Start tracking the fundamentals today.
