The process of planting miniature green plants on this underground farm is relatively simple: at first, the seeds of various plants are placed on lignocellulosic pulp, and after a few days the seeds are transferred to the shelves with LED lights. The LED lights on the farm are bright every day for 18 hours. At the same time, the strong fan will keep the temperature in the farm at 21 ℃ to 23 ℃.
This kind of underground farm to produce the plant growth cycle is relatively short, in the normal operation of the system, according to different varieties, farms within the plant only 6 to 28 days to harvest.

And this means that a new round of planting has already begun before the harvested plant is sent to the market.
