Low calorie stuff like herbs or lettuce are essentially the only plants that are practical to grow indoors at scale like this. Which makes perfect sense when you think about it but unfortunately means it will be very difficult to try to scale up to providing 2000 calories to a person, let alone the amount of plant matter chickens and cattle take. Edit: To clarify what I'm getting at here is the fairly linear relationship between how much artificial light is input and calories output. If your indoor farm is getting natural light, such as a greenhouse, then things are different.
