Given that there is (reportedly) a shortage of allotments around the UK
generally, and that with the overall demise of garden space urbanwise what
say the group about the idea of division of a very large ex-commercial
greenhouse into "units" for people to use ?

Thus far my idea is divide the existing 200ft x 80ft greenhouse into 10ft
square "plots", dividing if required by walls of tarpaulin or somesuch with
the front of the greenhouse as a shop/sales area for produce etc (Already
exists in reality).

Would there be problems with cross pollination and other issues?

Suggestions and constructive criticism welcome.
