Abstract: The present invention relates to a self-contained growth system that functions as a stand-alone growth system or combined with a hydroponic or aeroponic growth system for the controlled growth of plants. A Spiral Tower having an entry port for seedling or seeds embedded onto trays floating on a downward spiraling water flow provides a closed environment with optimum nutrient and growth conditions for each plant type. The Spiral Tower is capable of germinating seedlings in a closed environment for subsequent maturation in an aeroponic or other system. As a stand-alone growth system, the Spiral Tower is capable of the continued growth of certain early life plants. Other applications as a seed to harvest system used in harvesting wheatgrass and similar plants. The system is designed for cost-effective use in restricted space and in regions not conducive for commercial plant production.
