  • Cannabis cultivation

Growing successful marijuana is dependent on understanding what each part of the marijuana plant’s life stages are. One of the most important parts of the plant’s life cycle is the vegetative phase of the plant, or “veg”. During veg, the cannabis plant is mainly concerned with building it self as big and strong as possible via the creation of new leaves, growing of the roots and increasing the strength of the stems before entering the flowering phase.

What is the Vegetative Phase?

Once the cannabis seedling has produced its first set of true leaves, the vegetative phase of the marijuana plant begins. At this point, the plant will enter into a state of rapid growth. While the plant will be producing new leaves and increasing the size of its root system, the plant will not be producing flower structures. Instead, the plant will be expanding the diameter of the stems and producing large green fan leaves that can absorb light from the grow lights.

During veg, some strains of cannabis plants can increase in height and width extremely quickly, with some plants increasing by as much as several inches per day when given ideal conditions. The duration of the veg phase can vary greatly depending on the grower and their specific plans for the crop. Typically, veg can last anywhere from 2-6 months for the majority of growers.

How do Female Plants Grow in Veg?

Male and female cannabis plants typically look very similar throughout the veg phase of the plant’s life cycle. Both plants are in the process of developing the framework needed to support the development of flowers in the flowering phase of the plant’s life cycle. A female plant in veg should be able to:

  • Produce thick and strong stems
  • Produce large green fan leaves
  • Have many growing nodes spread across the various branches
  • Be growing upward and outward rapidly
  • Have healthy roots located below the top layer of the soil

Having a plant that can produce healthy growth in the veg phase can help give the plant the best chance at producing large and heavy flowers in the future.

When Can You Tell If a Female Plant Exists?

Most growers can easily determine the sex of their plants during the pre-flowing phase of the plant’s life cycle. However, some growers who have experience may be able to tell if the plant is likely to be a female based on the location of the growing node on the plant where the branch meets the stem of the plant.

In the end, female plants will develop small pre-flowers that contain small, hair-like pistils that will eventually develop into the bud structure of the plant. Male plants develop small pollen sacs.

Because only female plants are able to produce usable flowers, growers will often inspect their plants regularly to identify any male plants and remove them before they have the ability to pollinate any of the female plants.

Why the Veg Stage is Important

The veg stage of the plant is the base upon which the entire grow is built. The growth of the plant in the veg stage will directly affect the quality and quantity of the flowers produced by the plant. Providing your plant with proper care while it is in veg will usually result in the plant transitioning to the flowering phase with a solid foundation and producing a better crop.

There are several things that can affect the health of the plant during veg such as:

  • Light exposure
  • Nutrients
  • Air flow
  • Watering Schedule
  • Temperature/Humidity

Careful management of the veg phase will allow growers to establish a plant that has many branches which can equate to a larger harvest.

Some Interesting Facts About Cannabis Vegetative Growth

There are a number of interesting facts about the way that cannabis grows in the veg phase that many novice growers are not familiar with:

  • Cannabis plants can double or triple in size after they begin to flower.
  • Some growers will intentionally extend the veg phase to give the plant the ability to grow more and have more branches.
  • The way the plant is shaped in the veg phase can effect how the buds grow and develop.
  • Topping and Training are two of the most popular techniques used during veg to train and shape the plant before the buds begin to form.
