3 Claims

1. A light regulation method for promoting accumulation of cannabinoid substances, comprising:

adding an irradiation of a green light into an indoor growing environment of cannabis to improve the accumulation of levels and yields of tetrahydrocannabinol (THC) and cannabidiol (CBD); wherein a peak wavelength of the green light lies at 515 nm;

wherein the step of adding the irradiation of green light having a peak wavelength at 505-526 nm comprises a combined irradiation with other wavelength bands or independent irradiation;

in the combined irradiation with other wavelength bands, a light source comprises 18-42% green light;

wherein the light source used in the indoor growing environment is a LED light source;

the LED light source consists of 12.6% blue light, 37% green light, and 50.4% red light;

the ratio of a photon number of the blue light to a photon number of the red light is 1:4;

an initial light intensity is 80 μmol/m²s, a maximum light intensity is 1000 μmol/m²s, and a photoperiod is 10-16 h/d.
