A Japanese inventor developed a thin film made of hydrogel that can absorb plenty of water and nutrients. It can be placed on any flat surface. The plants grow on top of the film and their root systems spread out like a fan. The hydrogel gives the plants all they need and the film stops bacteria and viruses from infecting the plants. film (塑料) 薄膜 hydrogel/ˈhaɪdrəˌdʒɛl/水凝胶 One such method was film farming, which was invented in 1995. $$
