The present disclosure is directed to improved vertical farming usingautonomoussystems and methods for growing edible plants, using improved stacking andshelving unitsconfigured to allow for gravity-based irrigation, gravity-based loading andunloading, along witha system for autonomous rotation, incorporating novel plant-growing pallets,while beingphotographed and recorded by camera systems incorporating threedimensional/multispectralcameras, with the images and data recorded automatically sent to a databasefor processing andfor gauging plant health, pest and/or disease issues, and plant life cycle.The present disclosureis also directed to novel harvesting methods, novel modular lighting, novellight intensitymanagement systems, real time vision analysis that allows for the dynamicadjustment andoptimization of the plant growing environment, and a novel rack structuresystem that allows forsimplified building and enlarging of vertical farming rack systems.
