Lufa Farms
From the lufa farms website: We grow food where people live and grow it more sustainably. This means growing on no new land; capturing rainwater; recirculating 100% of irrigation water and nutrients; reducing energy use; composting green waste; using biological controls instead of synthetic pesticides, herbicides, and fungicides; and delivering produce to customers on the same day itﾒs harvested. This also means developing the expertise and technology to make this type of agriculture efficient, data-driven, and scalable. In doing so, weﾒre demonstrating that large urban and peri-urban rooftop farms are a commercially viable ways to feed cities.
