> Vertical farming makes sense when energy is cheaper than what we get from the sun that's just part of it. Closer to the poles, away from the equator, there isn't enough sun to have a winter growing season. The energy, expense of transporting produce to those areas is another factor. Along with the flavor and quality benefits of harvesting when ripe instead of optimizing for transportation durability and presentation. Historically the solution was canning the in-season produce and consuming that during winter months.
