Wow this is very interesting and exciting, I must admit that I am a lover of soil and love to grow my food in soil, but this really deals with a lot of issues that growers face in small and even non existent places.
In saying that I have grown wheat grass this way very successfully. obviously very small scale though. It is so impressive the volume of greens that can be grown inside the container, thanks for this xx
Yet another great use for storage containers
