Closed loop self-watering sub-irrigation planter

A self-watering planter comprising:

• a planter body that has a bottom end and a top end, the planter body including a base wall at the bottom end and at least one side wall extending from the base wall to the top end of the planter body, the base wall and the at least one side wall defining an interior environment, wherein the base wall and the at least one side wall comprises an inner shell, an outer shell, and a structural layer between the inner shell and the outer shell, wherein the structural layer is a lattice with air spaces defined between the inner shell and the outer shell;
• and
• a divider integrally connected to the planter body so that the self-watering planter has a one-piece, unitary construction, the divider disposed within the interior environment, the divider including a tubular section that has a cylindrical shape, the tubular section including a lower end connected to the base wall and an upper end that is open, the divider including a planar section radially extending from the upper end of the tubular section to the at least one side wall,
• wherein the divider defines a first soil space within the interior environment located above the planar section, a second soil space within the tubular section, and a fluid reservoir below the planar section and outside of the tubular section,
• wherein the lower end of the tubular section is seamlessly connected to the inner shell at the base wall and the planar section is seamlessly connected to the inner shell at the at least one side wall, and
• wherein the divider includes a plurality of aeration holes along both the planar section and the tubular section to permit water transfer through both the planar section and the tubular section, between the first soil space, the second soil space, and the fluid reservoir, while restricting soil transfer.
