Before stepping into Plenty Inc.’s indoor farm on the banks of the San Francisco Bay, make sure you’re wearing pants and closed-toe shoes. Heels aren’t allowed. If you have long hair, you should probably tie it back.
Your first stop is the cleaning room. Open the door and air will whoosh behind you, removing stray dust and contaminants as the door slams shut. Slide into a white bodysuit, pull on disposable shoe covers, and don a pair of glasses with colored lenses. Wash your hands in the sink before slipping on food-safety gloves. Step into a shallow pool of clear, sterilized liquid, then open the door to what the company calls its indoor growing room, where another air bath eliminates any stray particles that collected in the cleaning room.
