Some crops, e.g. tomatoes and cucumbers, requires support. Intensive indoor growing leads to high production which result in heavy load on the trellising system. The up-to-date trellising systems rely on the structure of the greenhouse. Thus, trellising system includes not only the cables and wires upon of which the plants rely on, but also extra reinforcements that enable the structure to carry loads up to 25-80 kg/m2.
