Apparatus for growing Cannabis is created from a conventional rectangular shipping container with fork lifting channels in the floor and having stacking connectors by which one container can be stacked on another and includes standing plant support racks arranged at stationary positions along sides of the container for receiving plants thereon at a selected stage of growth, typically the flowering stage. First and second rows of lighting components are arranged on respective sides each with a cooling duct extending from a filtered inlet at the front to an extraction fan at the rear. The lighting is carried on two longitudinal cable rails each along a respective side. The air-conditioning system includes two exterior condensers mounted on the rear panel above the center line each supplying at least two interior evaporators. The front panel of the container is removed and replaced by a new front panel with a central door.
