Abstract

A method of plant cultivaton and growth acceleration includes enclosing the plants within a reflective chamber, controlling the CO.sub.2 concentration within said chamber so as to be at least 200 ppm, and irradiating the plants substantially omnidirectionally with a light intensity of approximately 3000 lux, while stably regulating the ambient temperature, relative humidity and nutrient supply.
