This was announced by the Mebiol Development Center in Tokyo, where it became possible to grow fruits and vegetables on a seemingly ordinary transparent plastic film. 
But according to the project director, Hiroshi Yoshioka, this film is not quite normal. It can absorb water through a hydrogel and transfer beneficial substances to the plant. Such a method is similar to growing with hydroponics, where growing on water plays a key role. But according to the creators, their method is much better than the one presented above, because the hydrogel uses less water during growth and also has “block-pores” that microorganisms and bacteria do not get into.
