Excellent article, thank you.

Although I am very excited about the prospect of vertical farms, my immediate thought is of mycorrhizal networks. How are the services (pest control, nutrient supply, root growth support etc) replaced in a vertical farm? Furthermore, is the produce from vertical farms comparable to current crops in terms of nutritional value, or to the far superior crops from the time prior to the post Green Revolution destruction of soils? I also wonder at the lost benefit, or in fact serious detriment, to our own body’s (particularly the gut’s) biome to eating crops grown in a sterile environment.
