Question: How big would he vertical farms be? like the size of a cupboard or like a front room on a wall?

It depends on your imagination. As an engineer you can design the vertical farm and personalise it as much as you want. It can be small and portable so that people can have it in their kitchens, or it can be as large as a wall and cover one side of your dining room or classroom. It also depends on the purpose of the farm. If it’s designed for self consumption in a house, a small system can be enough. If it’s designed to feed a school it could be larger and attached to a wall. If the purpose is to sell the produce to the market, then the farm can be installed in a large greenhouse. As you can see, the possibilities are endless!
