Definition - What does Florigen mean?
In gardening, florigen refers to a hypothesized hormone that triggers and controls flowering in plants. This hormone is produced by the plant’s leaves. In marijuana, for example, the manipulating light and darkness has been shown to trigger florigen production. This hormone was first discovered in 1865 by German scientist Julius von Sachs.

Florigen can come in particularly handy when it comes to indoor gardening since the plant’s exposure to sunlight is limited. Manipulating florigen has been shown to encourage plants to thrive and flower, in spite of a lack of sunlight. By this token, florigen supplements are also used in the winter. 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.
