????Luo Songsong ????songsongluo@126.com ????BEIJING-BASED tech enterprise BOE is displaying its innovative four-layer vegetable-growing container, which uses intelligent systems to help people grow leafy green vegetables at home, this week at the 15th China Hi-Tech Fair in Shenzhen. ????Replacing natural sunlight with LED technology, the container’s support systems can automatically control interior temperature, humidity and carbon dioxide content in a controlled environment. Users can watch their vegetables grow through glass and adjust conditions on a high-definition touchscreen that can be connected to a home computer. ????“The zero-cost, non-GMO seeds and quality nutrition fluid developed by the Chinese Academy of Agricultural Sciences contain no pollutants or chemical substances and can 100-percent guarantee vegetables’ survival rate, safety and taste,” said BOE’s Li Yaohui, director of the project. ????The containers can grow more than 20 kinds of vegetables, with maturation periods of 30 to 45 days. ????The product’s major cost is power consumption, which Li said usually amounts to about 20 yuan (US$3.26) per month. |
