A restaurant in Chicago, Uncommon Grounds, grows organic produce on their roof and uses solar to heat 50% of their water while Lufa Farms in Montreal is building a a 31,000 square foot rooftop greenhouse.
“Our goal simply is to be a neighborhood food source and raise the bar on the issue of traceability. We think it’s important that people know where their food comes from, that they can say, ‘Yes, I can see where my food is grown. It’s grown right over there.'”
The greenhouse is designed to withstand Montreal winters as well as producing over 25 types of vegetables – with no pesticides or herbicides.
