Measuring nutrient solution strength
is a relatively simple process. However, the electronic devices manufactured
to achieve this task are quite sophisticated and use the latest microprocessor
technology. To understand how these devices work, you have to know that
pure water doesn’t conduct electricity. But as salts are dissolved into
the pure water, electricity begins to be conducted. An electrical current
will begin to flow when live electrodes are placed into the solution. The
more salts that are dissolved, the stronger the salt solution and, correspondingly,
the more electrical current that will flow. This current flow is connected
to special electronic circuitry that allows the grower to determine the
resultant strength of the nutrient solution.
