Indoor Plant Factory Case
The 'plant factory' not only fully utilizes social spatial resources, but also promotes economic growth in the surrounding areas of the farm. On weekdays, it is a garden that provides healthy organic ingredients, but on holidays, it transforms into a farmer's market that shares and enjoys with surrounding residents. It is a new type of agricultural park that integrates circular agriculture, industrial symbiosis, and agricultural leisure, bringing new vitality to communities lacking healthy food choices.
A plant factory is a facility agriculture form that operates in a fully enclosed, multi-layered, artificial or mixed light environment, using the Internet of Things, robots, AI algorithms, and precise environmental control to achieve unmanned and year-round continuous production of "sowing seedling planting growth harvesting cleaning packaging".
