Modular self-sustaining planter system

A planter system comprising:

• an elongated upright support member having one end positioned on a horizontal surface;
• a plurality of individual planters, wherein each planter is attached to the upright support member via an upper hollow support bar and a lower hollow support bar, each said upper support bar being angled downwardly from the upright support member toward its respective planter, and each said lower hollow support bar being angled upwardly from said upright support member toward its respective planter;
• a first fluid delivery conduit connected between an upper hollow support bar located farthest from said horizontal surface and a fluid reservoir, wherein the fluid delivery conduit is in fluid communication with the fluid reservoir and the upper hollow support bar;
• a plurality of fluid return conduits, wherein each fluid return conduit connects a lower hollow support bar of a higher planter to an upper hollow support bar of a next lower planter, and provides fluid communication from an outlet of the higher planter to an inlet of the lower planter;
• a pump mechanism connected to the first fluid delivery conduit to deliver fluid from the reservoir through the fluid delivery conduit to the upper support bar located farthest from the horizontal surface, wherein fluid will flow from each higher planter through its respective lower support bar and fluid return conduit, and into the next lower planter through an upper support bar until it exits a lowest planter and returns to the reservoir, such that fluid will flow through each of the planters under gravity.
