Florigen

What Does Florigen Mean?

Florigen is the key hormone in plants that promotes flowering. The plant’s system starts producing florigen when the days grow shorter and the nights grow longer.

Chemical compounds start being produced in the growing points of the plant, which spurs another chemical reaction in the leaves of the plant. The plant's system flows the two chemical compounds together to create the flowering hormone known as florigen.

Maximum Yield Explains Florigen

Florigen was first discovered in 1865 by German scientist Julius von Sachs.

Florigen production is triggered in short-day plants such as cannabis when the days start to shorten and the plant is exposed to longer periods of darkness. It has been discovered that exposing a marijuana plant to pure darkness for a period of 24 to 30 hours will stimulate its production of florigen and trigger its flowering cycle. This allows a grower to synchronize a cannabis plant’s pre-flowering stage and control its production by inducing flowering.

Scientists have also used florigen to grow tropical plants in hostile growing environments such as Northern Europe, a feat that was previously deemed impossible.

According to plant physiologist Mikhail Chailakhyan, it is possible to transmit a graft from a plant that has been induced to flower to a non-induced one in order to transmit floral induction.
