Vertical farming involves growingplants indoors， which is why its some?times also known as indoor farming.Instead of sunlight and rain， vertical farmsuse LED lighting and controlled growingand nutrition systems. Plants are stacked（放成整齐的一堆） vertically in layers， somany of the farms look like warehouses filled with large shelving units.

Vertical farming is considered a highly efficient and sustainable way of producingfood. For instance， it uses 250 times less water than a traditional farm would need. Automationis the key to this efficiency. Software， robotics and data science are some of the technologiesused in vertical farms to monitor crops and create best growing conditions.

Controlled environment agriculture like this helps to reduce the vertical farms environmentalimpact， getting rid of the need for pesticides for example. Vertical farmsalso dont rely on the weather， so fresh produce can be grown all year round.

Instead of growing fruit and vegetables on big farms and then transporting them overlong distances in trucks and planes， vertical farming can supply local produce from neighbourhoodbuildings. This means less fuel is used and the food is fresher.

Vertical farms also tend to produce more than traditional farms. Experts say plantscan be harvested 15 times a year. In a traditional field， harvesting is twice a year.

By precisely controlling the growing environment， products can last for 13 to 14days， against three to four days for the equivalent products from traditional agriculture.

However， cost is a big hurdle for vertical farming. Sunlight and rain are free. PoweringLED lights， software and complex growing systems arent.

While some facilities run on electricity from wind turbines， vertical farmsrunning on fossil fuels may be adding to the problem of climate change rather thanmaking it better. Buying urban real estate to build vertical farms can also be expensive.

“ Its our mission to cultivate a sustainable future to meet global demands for freshand local food， and this new farm is the manifestation （表明） of that commitment. This newfacility serves as a model for whats possible around the globe，” says an expert.
