News Summary: Indoor farming takes root in Midwest

INDOOR FARMS: Indoor farming is a hot trend in the Midwest, a region known more for its massive hog, corn and soybean farms than for crops of boutique organic greens.

GREEN THUMBS: Farming in abandoned warehouses lets entrepreneurs grow more food locally in spaces that are typically cheap. Farmers have had the most success with greens such as herbs and lettuce, although they are experimenting with all kinds of crops.

THE DRAWBACK: The cost of power to heat the massive spaces and run the lights that help the plants grow is the biggest stumbling block for the facilities.
