A method for promoting the accumulation of secondary metabolites of cannabis is disclosed. The method comprises the step of adding a green-yellow light, which has a peak wavelength at 506-571 nm, into the indoor growing environment for cannabis, and maintaining the light intensity and other growth conditions, to improve the content of secondary metabolites. The production of secondary metabolites of cannabis can be increased by up to 18%.

A method for increasing floral yield of a flowering plant includes positioning the plant between side lights at the onset of a flowering stage of the plant, such that the plant is flanked by the side lights. The method also includes irradiating lateral sides of the flowering plant along the total height via the side lights with light in a predetermined red spectrum range for a duration of the flowering stage, such that at least 80 percent of the light has a wavelength of between 580 nm and 780 nm. The plant may be positioned between first and second sets of equally-spaced elongated side lights on respective first and second lateral sides of the plant. Supplemental lighting devices may be attached to the plant, with an interior of the plant irradiated with the red spectrum light for the duration of the flowering stage using the lighting devices.

Embodiments described herein provide systems for optimizing organism growth, destruction or repair, by controlling the duty cycle, wavelength band and frequency of photon bursts to an organism, through the high frequency modulation of photons in an individual color spectrum to the organism, where the photon modulation is based upon the specific needs of the organism. Devices for the optimization of organism growth, destruction or repair through the high frequency modulation of photons of individual color spectrum to the organism are also provided. Further provided are methods for the optimization of organism growth, destruction or repair through the use of high frequency modulation of photons of individual color spectrums.

The present invention relates to a method for stimulating the resistance of plants to biotic stress by radiation exposure of at least one spot of a plant characterized in that the radiation exposure is performed by UV-C rays alone or UV-B rays alone or a combination thereof with an exposure duration being less or equal to one second and the radiation exposure being repeated at least once with an interval of time between one hour and one month. The invention will find an application for stimulating natural defenses of plants to biotic stress as pests, bacteria, fungus or virus. The invention could be used directly on plants growing in fields for agriculture and the food industry.
