The stackable plant container module is adapted such that a plurality of plant container modules will nest together for storage and/or shipping while allowing the plant container modules to be stacked vertically into a multi-level plant tower. The stacked plant tower includes a water bowl, defining a reservoir for receiving water, carried by the upper most plant container module, and a water tray disposed between stacked plant container modules. The stacked plant tower is adapted such that the water bowl is in fluid communication with each water tray, such that the stacked plant tower incorporates structure for managing the flow of water through the stacked plant tower.
