So far, BrightFarms either has built or plans to build greenhouses and rooftop farms in New York, Chicago, St. Paul, Oklahoma City, St. Louis, Indianapolis, and Kansas City. Their first greenhouse—a 56,000-square-footer—is in Bucks County, Pennsylvania.

Actually, apparently it has been known for 2 years. Found the NewsOK article that was already posted here.
