Lighting is essential whatever growing marijuana indoors or outdoors. The Photoperiod of marijuana flowering is directly related to the quality and total yield of crops. So you need to understand the marijuana plant light cycle.

Vegetative  is the stage of plant growth. This stage is critical to the success and health of cannabis plants. At this stage, the stems and leaves of cannabis plants begin to become larger and taller. However, at this stage, the cannabis plant will not produce any flower buds. You must control the shape and size of the plant. At this stage, the light of your plant can be controlled to produce better growth. The more light the cannabis plant receives, the better its growth and future yield will be.

When the cannabis plant is in the vegetative stage, it is exposed to grow light for plant at least 18 hours (also known as 18 / 6).
