A hydroponic Green façade is a constructive system that allows to plant vegetable species in the entire vertical surface of a façade. The structure that supports this system is affixed to the façade. On this structure are placed different layers and a hydroponic substrate in which the plants grow.
Green façades usually do not require any extra structural requirements. They are most commonly attached to concrete walls, but can attach to almost anything, or even be free-standing. We can remove this NBS easily if we want.
Green façades get the recovery of the investment between the 10 and the 20 years. Hydroponic green façades are more expensive than the green façade with climbing plants.
