Authorities swarmed through a large marijuana field in the Conroe area early Wednesday morning.

Between 10,000 and 20,000 plants were found at the farming operation in a heavily wooded, rural area on private land, according to the Conroe Police Department. The plants were valued at about $500 each.

Police asked that the exact location of the field not be released.

The property owners, police added, were not connected to the growing operation and knew nothing about the plants.

Police said no people were found at the field, but officers discovered several sleeping cots as well as food, water and generators. So far, no suspects have been found and no arrests have been made.

Police officers will cut down the plants and burn them.
