They look more like the brightly-lit shelves of a chemist’s than the rows of a vegetable garden. But, according to their creators, these perfect-looking vegetables could be the future of food.

In a  41   controlled environment -unpolluted by dirt, insects or fresh air -Japanese scientists are developing a new way of growing vegetables.

Called plant factories, these greenhouses have  42   up across the country and can produce perfect-looking lettuces and green leaves 24 hours a day, seven days a week.

Every part of the plants’ environment is controlled -from the lighting and temperature to the humidity (湿度) and water. Even the levels of carbon dioxide can be  43   altered.

Rather than the conventional untidy clothes and dirty fingernails of vegetable growers, the producers wear gloves, masks and dust-proof  44   suits.

The vegetables from plant factories are sold at a price above the normal price of vegetables to Japanese shoppers. No chemical  45   are used so there is no risk of food poisoning.

Because the plants are grown in a clean room, they can be eaten safely without washing. Lettuce grown in the factories can be  46   up to 20 times a year. Some factories are vast and can produce three million vegetables a year.

The spread of plant factories has been  47   by the Japanese government among concerns   about the use of chemicals in vegetables.

A spokesman for the Ozu Corporation factory in Tokyo said, "Vegetables are produced in the factory without being exposed to the air outside. Stable production is  48   throughout the year by controlling lighting, temperature, humidity, carbon dioxide and water. They can also meet the demands of  49   who want safe food."
