Abstract: An apparatus for growing vine crops in a greenhouse comprises a first media carrier, a first nutrient supply means, a first support means, a regulating mechanism, a main cable, a plurality of load differential mechanisms, a second media carrier, a second nutrient supply means, and a second support means. The second media carrier is above and in substantial parallel with the first media carrier. The distance between the first media carrier and second media carrier is adjusted by the regulating mechanism. A method for growing vine crops in a greenhouse comprises two growing modes: a single crop growing mode, and a vertical dual crop growing mode. The sequence of this process begins with a first single crop growing mode, followed by a vertical dual crop growing mode, and then followed by a second single crop growing mode. A single crop growing mode: first crops grow in the first media carrier fed by the first nutrient supply means, trained by the first support means.
