Cannabis Flowering Stage Week By Week, The Flowering cycle is the third major cycle after the Germination and Vegetative cycle.
The flowering cycle of a Cannabis plant is very similar to that of any other plant and herb.
How long does the cannabis flowering stage last?
The Flowering cycle of a Cannabis plant can take between 6-24 weeks depending on the individual strain.
When does the cannabis flowering cycle start?
The average flowering cycle starts when a Cannabis plant receives 12 hours of light followed by 12 hours of darkness.
In nature, this is season dependent, during the long summer days (18+ hours of daylight) a Cannabis plant grows, and when the days get shorter certain actions are triggered telling the plants it is time to grow reproductive flowers.
More detailed info on available in the “Grow Light” section.
A Cannabis flower, sometimes known as a bud, is the reproductive structure found in Cannabis plants.
The biological function of these flowers is to affect reproduction, the pollen (sperm) of the male Cannabis plant collected by a pistil of a female Cannabis plant will result in a fertilized egg inside each calyx.
Each fertile (pregnant) calyx will produce a seed.
Cannabis Flowering Stage Week By Week
Weeks 6 and 8,
A Male Cannabis plant (Staminate)
B Female Cannabis plant (Pistillate)
1 Stamine (Male) flower, the pollen-producing reproductive organ of a Cannabis flower
2 Anther, a single pollen sack from a male plant
3 The anther after releasing its pollen
4 A single grain of pollen from a male Cannabis plant
5 A single calyx from a female Cannabis plant, the two long tentacles are called the stigma
6 After pollination, the seed embryo starts to grow
7 When the seed is formed inside the womb the stigma will wither and die
8 When mature the seed will emerge from the wilting female plant
9 Just after “birth”, the seeds are swollen and full of moisture
10 After a few weeks of resting the seeds dry out and harden, ready to start germinating
Cannabis Flowers may facilitate outcrossing (fusion of sperm and eggs from different strains of Cannabis) or allow selfing (fusion of sperm and egg from the same flower).
In addition to facilitating the reproduction of flowering plants, Cannabis flowers have long been admired and used by humans as objects of rituals, religion, medicine and their seeds as a source of food.
Cannabis normally has gender-specific flowers, with staminate “male” and pistillate“female” flowers occurring on separate plants.
It is the female Cannabis flowers that will produce the medicinal Cannabinoids used for both medicinal and recreational purposes.
It is not unusual, however, for individual plants to bear both male and female flowers, these plants are often referred to as “hermaphrodites”.
