Nominal EC Values for Hydroponic Crops

Below is a list of crops with the ideal EC value the crop is grown at in a hydroponic system for optimum performance.
Although there are ideal EC values for each plant type, this does not mean that a range of plants, all technically requiring different strength nutrients, cannot be grown in a home situation together.
The grower simply lists the range of EC values and picks an average value. For most home systems this value is between 1.2EC and 2.0EC depending upon the requirements of the predominant crop types being grown.
