exactly how you grow marijuana on essentially an indoor farm. so where does it start? >> it starts here in the lab. >> reporter: with cuttings known as clones. >> get a little gel on there. >> reporter: that go into these tanks for about two weeks, then this room for about five weeks under simulated sunlight in a co2-rich environment. >> each plant has its own bar code? >> that's right. every single plant when can comes out of the cloner is coded individually. we're able to trace that plant from this stage all the way to the end product. >> reporter: then the light is cut back to simulate the shorter days of autumn, triggering the plants to flower, and finally it's off to be trimmed and dried. the entire process is regulated by the state. after a criminal background check, employees are issued a worker i.d. card. every time a plant is moved, the employee logs it using this software, a fingerprint scanner tracks the employees at every turn. >> there's no scarface here, no ak-47s. none of that stuff.
