Very interesting idea for farming inside of stackable used shipping containers. Read the comments for an almost better slice of information than the article itself.
Looking at the picture showing the inside of the container immediately screamed “wasted space”. Imagine that whole space filled top to bottom with shelves of plants, soil, plus light vertically stacked inside. Imagine the curation of the plants is taken care of by a very simple set of robots on wires/rails that move along the length/width of the container. Think of those little spray hoses in the produce section of your grocery store. Imagine then that you could mount small color cameras to keep an eye on all of the plants. The same cameras could easily measure the growth of a given plant. The soil could be monitored … well, the same way that it is now. The same soil probes could monitor moisture and control the watering robots overhead as well as the sun lighting system.
You would have full data on your environment — what works, what doesn’t. Full records of environmental air and soil conditions, completely controllable by the farmers. You would have records of the plant growth over time. How sexy would all of those graphs be?
