Did you know? There are nearly 15,000 acres of "food crops grown under protection," in North America, according to the U.S. Department of Agriculture's most recent Census of Agriculture.
Of the total, 2,250 acres are in the U.S., 3,608 acres are in Canada, and 9,084 acres are in Mexico.
Greenhouse acreage grows every year, says greenhouse vegetable consultant Gary Hickman, a retired greenhouse horticultural adviser for the University of California, Davis who now operates Cuesta Roble Consulting in Mariposa, Calif.
U.S. production alone gained more than 800 acres since 2007, and Hickman says plans are in the works for 1,247 new acres in the U.S., 810 acres in Mexico and 385 acres in Canada in 2017.
