The Mall of the Americas in Miami was home to a business not usually found among the food courts, retail stores and movie theaters of similar locations: a hydroponic nursery with more than 200 marijuana plants.

Federal agents seized the plants on Friday. The grow operation was found deep in a storeroom at the mall. Authorities say the growers used the mall's electricity to power their equipment, adding the flimsy wiring could have caused a fire.

Agents would not say how the drugs were found, and no arrests have been made.
