The paper presents an efficient form of growing arugula plants by means of automatic control of an aeroponic culture irrigation system. The system considers a reprogrammable electronic circuit that uses software to generate different irrigation cycles to obtain an adequate growth of arugula crops. Results show how different samples grown in a greenhouse had the same growth behavior as field-grown samples during the test period. It was possible to obtain a more efficient and sustained five-week production to supply consumers by having a continuous cycle irrigation system, which was operated for 35 d. The growth and number of leaves were maintained in a similar way for different plants analyzed. Roots grow similarly, but some of them showed size differences during the five weeks.
