I remember those boxes to grow salad in, vertically stacked, interesting concept because no need for toxic stuff and almost no water, and it’s right there so no need for shipping.
Been growing plants for 30-years, using zero sunlight to full sunlight. The difference in energy use, manpower, all that, is stunning.
