How do you know if EC is runoff?
Measure the EC of the Run-off You simply turn on the meter and lower it into either the nutrient solution you will be delivering to the plant or the run-off that passes through the media. It is important to always measure the EC of the inflow and to periodically measure the EC of the run-off.
