Tomato production in greenhouses is already vertical if you consider that the plants are grown up to 6m (20ft) high. The plant length at the end of the growing period is roundabout 15m-20m (50-65ft), since the plants are treated in a way that keeps one main branch growing at the top while pruning everything below harvest line. https://s-media-cache-ak0.pinimg.com/originals/19/c4/53/19c4539e7860d1288ecbdeaddedd5347.jpg https://s-media-cache-ak0.pinimg.com/originals/19/c4/53/19c4...
