Underground air raid shelter still has this effect? Lighting vegetables with LED

The underground air raid shelter at the kabamu high street railway station in southern London has provided thousands of people with shelter during World War II, the Guardian reported on September 13th. After 70 years, the huge underground tunnel system has been transformed into youth - transformed into an underground farm.

According to reports, the underground farm belongs to a company called "0 carbon food". The company's main business is to produce rich, miniature green plants on underground farms by hydroponics. The process of planting tiny green plants on this underground farm is relatively simple: at first, seeds of various plants are placed on wood fiber pulp. After a few days, these seeds are transferred to the shelves with LED light clusters. The LED lights on the farm are bright for 18 hours a day. At the same time, the strong fan will keep the temperature in the farm from 21 to 23 degrees Celsius.

This underground farm produces a shorter plant life cycle. Under normal operation of the system, the plants in the farm can harvest only 6 to 28 days depending on their varieties. The harvested plants on the underground farm will be sent to a high London restaurant in a few hours. Unlike other traditional farms, the underground farm can operate throughout the year. This means that a new round of planting has already begun before the harvested plants are sent to the market.

It is reported that the company is expected to sell all kinds of miniature green plants produced next month. At present, the "0 carbon food" company sells mainly 8 kinds of miniature plants, including celery, mustard and radish. "Our first underground farm has grown to 550 square miles and can produce 700 boxes of plants a day at full load," said drin, one of the founders of the 0 carbon food company. In addition, the company is expected to expand the planting area of underground farms to 2200 square miles in 2 years.

At present, the prospect of miniature green plants is very broad. Ballard, another founder of the "0 carbon food" company, said: "the development of the micro green plant market is not mature at present. If necessary, we can turn the product into an agricultural product that can be harvested within 30 days." "At present, our products are mainly provided to restaurants, but with the promotion of TV programs, more and more people will understand and love our products," Ballard said.
