LED grow lights help Fujian plant factory producing

A LED lighting plant factory in Fujian, China, with an area of 10,000 square meters, is the largest plant factory in the world.

Although the vegetables can grow in the normal environment, all the vegetables in the plant factory must be grown in the clean space to avoid diseases and insect pests. Therefore, the staffs are requested to have a series of complicated and rigorous disinfection procedures before entering the production area.

In the huge workshop, rows of plant cultivation modules are neatly arranged, just like a large supermarket. The top of each layer of cultivation racks are covered with LED grow lights, and various lettuce and cabbage are planted on the cultivation racks. Although there is no soil, and no sunshine all year round, these vegetables are growing strong.

The plants need different light in different growth stages. Therefore, the plant factory can control the quality and yield of vegetables by adjusting the LED grow lights, which is impossible to sunlight. For example, in the seedling stage, the factory can make seedlings grow stronger and synthesis more soluble proteins through increase the blue light ratio of LED grow lights.

Beginning in 2016, the vegetables grown in the plant factory entered the market and received positive market feedback. The lettuce produced in the plant factory is placed in a cold air cabinet, a pack of 150 grams, priced at 9.9 yuan, and 150 grams of ordinary lettuce is less than 1 yuan. The price disparity is so large, but consumers still think that the vegetables produced by plant factories are healthier and more nutritious.
