I am currently trying to collect information on 4 season gardening projects that are community based within a larger structure. This is something I am doing a paper about, the viability of a 4 season indoor community gardening project.

I am located in Minnesota, so I am wondering if anyone has heard of any projects that are taking place in northern climates say, at, or above 45 degrees latitude. I haven't had any luck finding any information of larger scale projects, my interest is that some of the abandoned buildings (after some work was done), could be retro-fitted to work with this like a large greenhouse. Links or directions are welcome.

Thank you.

Mike
