Why 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. From a scientific perspective, when nutrients are added, this creates the potential for electricity to move through a solution, increasing the electrical conductivity.
Measuring the temperature of your solution is equally important, as - if it’s too hot or too cold - this can affect the plants’ growth rate and structure.
Combine it with the Bluelab pH Pen to Expand your toolkit to cover all the 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.
By measuring conductivity, temperature and pH, you’ll not only be actively managing your nutrient levels but also making sure that your plants have access to the food they need. This will lead to healthier, thriving plants and improved crop yield. Start tracking the fundamentals today.
