Field crops, greenhouses, protected climate, and more recently vertical farming, are all well-understood entries in the horticulture lexicon. The term 'container culture' was coined as a way to represent another new growing system where ISO shipping containers are used instead of a field or a greenhouse or a warehouse.  Various approaches are already well-established in production systems, with varying levels of container customization and an array of different plants being grown and of course with an array of business models to support them.
