Singapore now has its first commercial vertical farm, which means more local options for vegetables.
The technique uses aluminium towers that are as tall as nine metres, and vegetables are grown in troughs at multiple levels.
The technique utilises space better — an advantage for land-scarce Singapore.
Sky Greens farm first started working on the prototype in 2009, and has opened a 3.65-hectare farm in Lim Chu Kang.
It produces three types of vegetables which are currently available only at FairPrice Finest supermarkets.
They cost 10 to 20 cents more than vegetables from other sources.
Despite the higher prices, the greens have been flying off supermarket shelves — via redwolf.newsvine.com
