Does the underground air defense cave have this effect? Planting vegetables with LED

According to the guardian in September 13th, the underground air defense cave at the high street station in krabum, south of London, once provided shelter for thousands of people in World War II. After 70 years, the huge underground tunnel system has been restored to youth, which has been transformed into an underground farm.

It is reported that the underground farm belongs to a company called "0 carbon food". The company's main business is to produce a strong micro green plant in the underground farm by water - farming. The underground farm has a relatively simple process of planting miniature green plants: at first, the seeds of various plants were placed on the wood fiber pulp, and after a few days, the seeds were transferred to the shelves with LED light plexus. The LED lights in the farm are all bright for 18 hours a day. At the same time, the strong fan will keep the temperature in the farm from 21 to 23.

The plant growth cycle of this underground farm is relatively short. Under the normal operation of the system, the plants in the farm can be harvested only 6 to 28 days according to the different varieties. The plants harvested in this underground farm will be sent to the senior restaurant in London in a few hours. Unlike other traditional farms, the underground farm is able to operate all year. This means that a new round of planting has begun before the harvested plants are sent to the market.

It is reported that the company is expected to sell the various miniature green plants that they produce next month. At present, the "0 carbon food" company mainly sells 8 kinds of plants, including celery, mustard, radish and other plants. "Our first underground farm has been planted in 550 square miles and can produce 700 boxes of plants a day at full load," said del De Lin, 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 micro 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 the moment, and if there is a need, we can change the product into agricultural products that can be harvested within 30 days." "At present, our products are mainly provided to the restaurant, but as the TV program is publicizing, more and more people will understand and enjoy our products," Ballard said.
