Inside a cannabis grow house in the San Fernando Valley

An indoor cannabis farmer invited a television reporter to visit his growing operation. He said he has 40 employees, seven indoor gardens, and earns $420,000 a year.

Mike admits his landlord doesn’t know he’s an urban farmer. His latest round of "OG Kush" will yield some 150 pounds of marijuana, a value of $510,000 turning over every 10 weeks. Mike’s partners at dispensaries in the Southland then sell the OG Kush by 1/8 of an ounce – sometimes more – charging $40 to $60 each.

"My biggest concern is staying out of the way of the Feds," he said, "but I don’t see myself doing anything else."
