The company's main business is through hydroponic method in underground farm flavored Mini green plants. The process of planting miniature green plants on this underground farm is simple: at first, the seeds of various plants are placed on the lignocellulosic pulp and, after a few days, the seeds are transferred to shelves with LED light clusters. The LED lights on the farm are bright 18 hours a day. At the same time, the powerful fan will keep the temperature in the farm from 21 degrees to 23 degrees celsius.
