Abstract: An indoor soilless plant cultivating system. The system has a plurality of (a) stationary light posts, (b) plant growth towers, and (c) irrigation means. Each post is adapted to illuminate a predetermined sector of an indoor facility in accordance with a predetermined illumination signature. Each tower is rotatable about a substantially vertical axis in accordance with a predetermined timing sequence so as to be exposable to the light generated at any given time by one or more of the light posts and that are arranged by at least one module defining a module darkened interior region within which plants being instantaneously positioned receive a sensation of nighttime. The irrigation means supplies the plants being cultivated in each of said towers with a nutrient-rich solution.
