Kyle Berlin tours America's "first official cannabis factory, a 60,000 sq. ft. facility in Oakland that would house 30,000 plants and could produce $50 million of cannabis per year":

Security will be an issue for any pot factory; cannabis sells at about the same price per ounce as gold, making this facility something of a horticultural Fort Knox.

"We're in talks with serious security contractors -- ex-military, ex-Navy SEALs, people with extensive experience guarding high-value properties," [Derek Peterson, co-founder of Gropech] said. "We've got one shot. If something happens -- if there's a break-in, or a worker is hurt, or something happens to the plants -- then every naysayer is going to come out of the woodwork and say, 'I told you it couldn't be done.'"
