It may be late April, but Barry Thoele is only a few days from harvesting his first batch of romaine lettuce in central Minnesota. Using huge plastic-wrapped greenhouses called "high tunnels" on his hydroponic farm, Thoele will raise and sell about 420 heads of lettuce each week from early May to December, in addition to spinach, basil, strawberries and other produce.
That's far too much for the local farmers markets, Thoele said, but that's OK.
"Most of this is already spoken for, between the hospitals and the school districts," he said.
Thoele is part of a relatively new food distribution model called a food hub.
The hubs purchase and aggregate locally grown produce in one place, or hub, so it can be sold and delivered to institutions. They have become popular because of the increasing consumer demand for fresher food in school cafeterias, retirement homes, hospitals and large restaurants.
But institutions don't have time to buy food from a dozen or more separate farms with different invoice systems and delivery dates, so the hubs simplify matters by becoming a single, go-to source.
Paul Hugunin, supervisor of the marketing division at the Minnesota Department of Agriculture, said food hubs seem to be "building steam" in the state. "Food hubs and distributors are changing the business model, and it's showing that local food is not a fad," he said.
"You're seeing farmers trying to react quickly enough and efficiently enough to supply that demand profitably," Hugunin said. "There's enough here to make investments of time and capital and energy."
