WHAT IS THE VEGETATIVE PHASE?

The vegetative phase is a period of the growing cycle that takes place after germination and before flowering.

After your cannabis seeds germinate, they’ll emerge from the soil as seedlings. These youngsters feature a short stem and two rounded cotyledons. Eventually, the first “true” leaves will form. Over the subsequent 2–3 weeks, seedlings will start to mature and produce a large number of fan leaves—structures required for photosynthesis. This marks the beginning of the vegetative phase.

The vegetative phase can last anywhere between 3–16 weeks (or longer), depending on the genetics of a cultivar and the goals of the grower. Explosive growth occurs during this time. Plants are typically transplanted into larger containers at the start of the vegetative phase to give their root system more room to expand. The main stem will ascend, and the space between nodes will increase dramatically. Indica cultivars will remain short and put out lots of lateral growth, whereas sativa varieties grow taller with much less ramification.For photoperiod varieties, the vegetative phase ends when the light cycle shortens.

Outdoors, this happens as the seasons change from summer to autumn.

Indoors, the lighting schedule is shortened to force photoperiod plants to flower on command. Plants will transition from the vegetative phase into bloom when exposed to a light cycle of 12 hours on and 12 hours off. In contrast, autoflowering cultivars initiate flowering based on their age as opposed to light cycle.

The germinated seeds peak out above ground and immediately spring up into small, blade-like green plants. ]]>
