　　Crop-growing skyscrapers摩天大楼 (第五段)

　　A major drawback of vertical farming, however, is that the plants would require artificial light. Without it, those plants nearest the windows would be exposed to more sunlight and grow more quickly, reducing the efficiency of the system. Single story greenhouses have the benefit of natural overhead light: even so, many still need artificial lighting. A multi-storey facility with no natural overhead light would require far more. Generating enough light could be prohibitively expensive, unless cheap renewable energy is available, and this appears to be rather a future assertion than a likelihood for the near future.
