Abstract
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%.
