I've been following the growth of so-called 'container farming' in cities around the country with considerable interest. Here's a Wall Street Journal report on the field.
NASA is even considering using the technology in space.
I'm wondering how viable something like this might be for backyard farmers. One wouldn't need to invest $80,000 per commercial container farm, as in the video above. Instead, one could buy a used container (for $2,000 to $3,000) and convert it oneself into a general-purpose farming environment, spraying insulation onto the interior surfaces, providing heating and/or air-conditioning, and setting up racks for seedlings. I see no reason why a family couldn't produce more and better food in such a containerized farm than they could in their own back yards - only they'd do it in much less space.
Theoretically, a home with a relatively small back yard, but big enough to accommodate a 20' or 40' container, might become almost self-sufficient in the production of essential vegetables and fruits. One might even have a neighborhood setup where different families grow different foods, and swap them among themselves to give everyone a balanced diet.
Is anyone doing that sort of thing at present? Do any of my readers know anything about it? If so, please tell us more in Comments.
