North Dakota tribe goes back to its roots with a massive greenhouse operation

BISMARCK, North Dakota — A Native American tribe in North Dakota will soon grow lettuce in a giant greenhouse complex that when fully completed will be among the country's largest, enabling the tribe to grow much of its own food decades after a federal dam flooded the land where they had cultivated corn, beans and other crops for millennia. Work is ongoing on the Mandan, Hidatsa and Arikara Nation's 1.3-hectare greenhouse that will make up most of the Native Green Grow operation's initial phase.
