Hemp vegetation

The growing phase of cannabis is the period of a plant’s life cycle, during which it grows and develops, rapidly increasing in size. There is an active set of green mass, branching and deepening of the root system, the formation of a central cola. It is at this stage that the phenotype of the plant is determined, and the foundation for its future harvest is laid.

At this stage of development, marijuana consumes the most nutrients, trace elements and moisture from the soil, which are used to create new cells and tissues. This also requires a lot of energy, which the plant produces through photosynthesis and active metabolism. To produce enough of it, the plant must receive an abundance of light and carbon dioxide. Only with the provision of everything necessary will it be able to please the owner with a plentiful and high-quality harvest.

Start and end of the cannabis growing phase
The growing season of marijuana begins immediately after the end of the seedling development. As a rule, this moment is marked by the appearance of the first five-pointed leaf or 3-4 internodes. Its duration depends on the type and variety of cannabis, as well as on the light regime. The growing season ends with the appearance of pre-flowers in the axils of the foliage and at the top of the central cola. It is at this time that the grower chooses the floor, and the grower can visually identify it.

Photoperiodic varieties
Photoperiodic hemp in its natural habitat enters the flowering phase after a decrease in daylight hours to 14 hours or less. Indoors, the grower himself has the right to control the length of the veg. He can turn the seedling into bloom even at 2 weeks of growth, but in this case you will not have to rely on a bountiful harvest.

Autoflowering varieties
The duration of the growing season of autoflowering marijuana varieties is determined at the genetic level. They independently enter the flowering stage upon reaching a certain age. They adopted this feature from ruderalis, a wild weed hemp that grows in areas with a short warm period of the year.

Typically, autoflowers go through the vegetation stage in 2-3 weeks. The moment of its end does not depend on the light regime. It is predictable for each individual variety.

Cannabis indica
Growth of indica cannabis occurs exclusively during the growing season. After entering the flowering stage, it completely stops. This means that the grower will only be able to harvest flowers from already grown branches. Typically, 3-4 weeks of veg is sufficient for indigenous marijuana strains to reach their full potential.

Cannabis sativa
Cannabis sativa is able to grow green mass even after entering the flowering phase. Growth rates are decreasing, but the formation of new branches and internodes continues. This feature is due to the natural habitat of this species. In a warm climate, the plant simply has nowhere to rush to leave offspring, because frosts will not come and will not destroy it.

This feature is very often used by impatient growers, bringing sativa plants into flowering stage earlier than indicas. This is usually done when the bush reaches a height of 30-50 cm. By the time of the harvest, such a plant will easily stretch for another 1-1.5 meters. Owners of small grow boxes should carefully monitor the size of the sativa bushes, because by the time of harvest they can easily increase their growth by 2-3 times.
