In accordance with the purpose of the invention, as embodied and broadly described herein, the invention is broadly drawn to a plant cultivation method whereby the plants are alternately under periods of pulsed light irradiating during an irradiation period followed by a non-irradiation (dark) period and whereby the light irradiation period pulses have an even or uneven pulse width between 1 to 60 seconds of irradiation, with a duty cycle of minimum 70 %, and a 0,1 to 15 seconds episodes of low-or non-irradiation in between the light irradiation pulses.
