Where imagination meets farming
Local-food pioneer Pete Johnson's movable greenhouses have yielded a lettuce harvest in the dead of a Vermont winter.
By Nancy Humphrey Case

When Pete Johnson, a leader among New England’s organic farmers, set out one day last fall to pull an 18,000-pound greenhouse, in fits and starts, over a field-grown plot of lettuce, he inched forward an idea that could help make fresh local produce available year-round, even in Vermont.It was late October. For most of his fellow farmers, harvest time was over until spring. But Mr. Johnson was just revving up his tractor – and his dream.

He wants to extend the growing season into winter, and to start spring crops in late winter, in ground protected temporarily by movable greenhouses. Johnson had seen this done experimentally elsewhere. But he was trying it on a commercial scale, with greenhouses 200 feet long – twice the length of a basketball court and two-thirds as wide.

He had been warned the project could be risky with such big structures. But Johnson – a young, well-educated trendsetter – was willing to take that risk.
