Vertical urban gardens

Singapore is applying the vertical model to urban agriculture, experimenting with rooftop gardens and vertical farms in order to feed its many residents.

Sky Green Director Jack Ng has created a vertical farming system, which he nicknamed ‘A Go-Grow’. It consists of a series of aluminium towers, some of them up to nine metres high, each containing 38 tiers equipped with troughs for the vegetables. In keeping with Sky Green’s focus on environmental sustainability, the water used to power the rotating towers is recycled within the system and eventually used to water the vegetables. Each tower consumes only 60 watts of power daily –about the same amount as a single light bulb.
