Cannabis plants don’t start developing flowers until they start receiving 12 hours of continuous darkness. Otherwise, they will continue to remain in the vegetative stage. As long as your cannabis plants are getting about 13 hours of light (or more) every day, you can keep your plants in this stage forever.

That is where the cannabis light cycle comes in: the light for your plants can be manipulated at this stage to yield better growth. The more lighting your cannabis plant receives, the better their growth and future yield.
