What if food growing

I think a lot of people have heard of the what if - project. Where food is grown in big grow bags on a vacant lot in Shoreditch. This is new way of bringing a housing estate together and helping to bring a sense of community. It is interesting to compare to the well established allotments at the Crown estate.

A good way of temporally testing out the idea of food growing without large scale investment in allotments. It would be interesting to see if anyone dares to give hens a go as well?
