Getting To Harvest: Flowering Cannabis

Lighting (or Sun) Controls the Flowering of Cannabis

Under cannabis’ natural growing environment outdoors, cannabis flowers in the fall when the days become shorter. Flowers begin to form during this last stage of growth, where leafy growth within the plant slows, and flowers begin to form.

The changing of the seasons signal changes within the plant, they go from being in a vegetative state to a flowering state. Seasons and the flower cycle of the plant are in direct correlation to the light spectrum that the sun is providing and the number of hours in the day the sun is shining.

The flowering of cannabis is triggered by twelve (12) hours of darkness and twelve (12) hours of light every twenty-four (24) hours. If left un-pollinated, female flowers develop without seeds, called ‘sinsemilla’ and if a female plant is fertilized with male pollen, the female flower buds will begin to develop seeds.

IF female marijuana flowers are left UN-pollinated, they continue to produce more and more resin within the buds. Naturally, the female buds are waiting for male pollination to complete their annual lifecycle. After several weeks have passed, the heavy flower and resin production of THC peaks in the unfertilized and frustrated ‘sinsemilla‘ buds.

When male cannabis flowers, the pollen is swept away by the wind and carried off to be caught by the female flowers to fertilize it. The male plant has finished its lifecycle once it has released its pollen.

The male plant then shrivels up and dies off. IF the male pollen can pollinate a female flower, the female flower begins to develop seeds. When the seeds come to maturity, they will then fall from the female plant onto the ground to then become germinated for the next season or to be collected and used for planting for the next crop.
