EC is the measure of electrical conductivity in your system and is influenced by the salinity of the solution. In other words, the more supplements and nutrients you add to your system, the higher the EC will be. Each crop type requires a different nutrient mix, and therefore, a distinct EC level. A lot of crops overlap, so don’t let your EC measurements limit you!
