A Lisbon farm plans to add 500,000 square feet of greenhouse operations over the next six years and defy doubters who don’t believe its style of year-round growing, which uses fish waste to fertilize greens, can be scaled into a large commercial operation.

Springworks Farm, the largest aquaponics farm in Maine and one of the largest in the United States, aims to be a local organic alternative to lettuce and other greens trucked from California and Arizona to the East Coast.
