These videos demonstrate how to create lush, productive gardens in apartments, balconies, and even indoors. From building your first small-scale system to understanding the symbiotic relationships that make these systems thrive, this corner of YouTube proves that the dream of "city homesteading" is not only possible, but highly accessible and rewarding.
