Abstract: A plurality of modular units are connected together on a slightly sloped drainage field with a perforated header pipe at the lower side conveying water away from the drainage system. An impermeable flexible liner cushioned on both sides is located below the modular units. The modular units are each made up of rigid boxes that have connecting cross slots at the bottom thereof and vertical perforations there through. The rigid boxes are lined with a drainage fabric that is site specific and have an expanded geosynthetic material therein, which is held in place when filled with porous granular material. High flexural strength mats are connected together over the tops of the modular units. An air inlet pipe connects air to the cross slots, down the sloped drainage field, to the header pipe to drain water from the bulk granular material resting on the high flexural strength mats. Some of the modular units have a pneumatic vibrator connected to a source of pressurized air.

Abstract: A plant growing system has a number of modular units arranged together on a flat surface in side of a growing room. The modular units have rigid boxes therein with vertical holes therethrough inside of which is located a growing soil. Water and nutrients are pumped from a reservoir to a distributor located in a growing soil of the rigid boxes as called for by moisture sensors, which activates a controller to turn ON a delivery pump. When moisture and nutrients need to be removed from an impermeable flexible liner located below the modular units, the controller turns ON a return pump, which pumps the excess water and nutrients back to the reservoir.
