    Vegetative stage —  The part of the cannabis plant’s life cycle where it is actively growing rather than producing flowers. When the plant receives 12 hours of light or greater, it will continue growing vegetatively indefinitely; when the light cycle reaches 12 hours or less, then the plant will begin flowering. During the vegetative stage, the plants prefer a more blue spectrum of light, commonly produced by fluorescent or metal halide (MH) bulbs, whereas flowering plants prefer the more reddish light produced by high-pressure sodium (HPS) lighting.
