Definition - What does Vegetative Stage mean?
The vegetative stage of the marijuana plant is the main phase of the plant’s life cycle. It immediately follow the propagation/germination stage, and precedes the flowering or bloom stage. The cannabis plant’s life stages are dictated by the sun.
While the plant receives at least 12 hours of sunlight per day, it remains in the vegetative stage, but as the night grows longer and the day grows shorter the plant starts to enter its flowering stage.
The plant’s entire vegetative stage is dedicated to growing a strong root system and stems to hold up large and robust flowers.
Hydrolife explains Vegetative Stage
During the vegetative stage of the cannabis plant’s life, it grows vegetation. It first develops its structure such as a strong root system and stem. Then the plant goes on to grow its abundant foliage. As long as the plant receives ample sunlight it will continue to grow in the vegetative stage.
Over two to three weeks, the plant will go through five or six growth spurts. Its branches will start to extend outward and develop. The cannabis plant can be forced to leave the vegetative stage and enter the flowering phase early by reducing its light exposure.
Once the marijuana plant starts to experience longer periods of darkness, it will put its efforts into flowering instead of vegetative growth.
Some grow room operators have separate rooms for each of the plant's stages: propagation, vegetative, and flowering. This allows them to have a perpetual grow room, with no downtime in their production.
