A new farming model is emerging in cities, it seems. Because sure, a rooftop garden is fantastic - but in Montreal? You're stuck with a short growing season due to the northern climate. So farmers are putting rooftop crops under glass and using hydroponic growing techniques to both lengthen the season and increase the potential harvest. Greenhouses give warmth to the air around the plants, and hydroponics allows farmers to avoid trucking heavy soil onto rooftops. It also allows them the control of nutrients needed for optimal crop growth.
BrightFarms is a new business that offers consulting services for those who wish to build urban rooftop hydroponic greenhouses. And they even partner with supermarkets. Pretty interesting concept.
I hope this look into new innovative ways to grow food in the city inspires you, even if you have acres of soil at your feet.
