The Bluelab Truncheon Nutrient Meter It is essential when growing with a hydroponic solution to KNOW what the strength of the solution is before feeding your plants AND while they are growing. This is easy if you use the Bluelab Truncheon!
Why measure conductivity…….to 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.
