When wheat seed meets a container, it gives rise to a containerized hydroponic grass factory. Systems such as sterilization, irrigation, fresh air, temperature control, air circulation, plant grow lights, environmental monitoring, and intelligent control are integrated into the container to ensure optimal growth of the grass. The grass is planted using a vertical cultivation shelf, with each level equipped with plant grow lights to simulate sunlight from 10 to 11 a.m. The seeds are spread on育苗盘 of identical size and placed on the vertical cultivation shelf, marking the beginning of a 7-day grass growth period. After 7 days, the harvest will be wheat seedlings around 20 cm tall, our 7-day grass.
