A system and method for cultivating plants is described. The system may include a tower structure having a vertical series of vessels for holding a netted pot or other container. The system may have a pressurized irrigation system that is in fluid communication with each vessel. The system may further include lamps to provide an adequate light source. The system may also include sensors, monitors and controls to establish and maintain environmental conditions suitable for proper plant growth. The system may further be implemented as a scalable system in which multiple tower structures may be installed into a scaffold system. Sets of towers may be slidably affixed to a scaffold such that the towers may be slid along a track thereby creating easy access to the plants, vessels, lights and the irrigation system. The system may be expanded to include multiple scaffolds affixed to a skeletal frame or compartment interior.
