The present invention comprises a modular horticultural growing system, creating a multitude of benefits through the utilization vertical growing capability and methodology. These benefits include increased growing densities, maximization of growing efficiencies, minimization of water usage, retention of nutrients, reduction of nutrient discharge into surface and ground water, increased growing capacity within existing capital infrastructure and space, reduction of energy and material inputs, cooling and beautification of structures and living spaces, increased local food production, synergistic effects throughout entire product, manufacturing, and production value chain, and many other benefits. The present invention allows individuals, especially those living in impoverished or densely populated urban areas, to grow a greater fraction of their food requirements. The preferred embodiment of is comprised of a hook, hanger, growing pot, hook trough and hook connector allowing for connection of additional growing units or other items to the bottom of each unit.
