Pontiac Silver Dome; The Largest Greenhouse in the World

I think the Silver Dome could be converted to the largest green house in the world.

Replace white roof with clear material; main floor is a huge growing area; seating area would be terraced; mushroom and composting in low light areas; plenty of water; abundent labor; many high tech engineers for automated planting, harvesting and controls; overhead/drop down harvest capability; plenty of room around the stadium for more greenhouses,energy windmills and solar panels
