Autoflowering cannabis or day neutral cannabis varieties automatically switch from vegetative growth to the flowering stage based on age, as opposed to the ratio of light to dark hours required with photoperiod dependent/short-day strains. Many autoflowering varieties are ready to harvest in less than 10 weeks from seed.
It is a short-day flowering plant, with staminate (male) plants usually taller and less robust than pistillate (female or male) plants. [4] [5] The flowers of the female plant are arranged in racemes and can produce hundreds of seeds. Male plants shed their pollen and die several weeks prior to seed ripening on the female plants.
A flowering cannabis plant. When cannabis is cultivated for its psychoactive or medicinal properties, male plants will often be separated from females. This prevents fertilization of the female plants, either to facilitate sin semilla flowering or to provide more control over which male is chosen. Pollen produced by the male is caught and ...
The length of the dark period required to induce flowering differs among species and varieties of a species. Photoperiodism affects flowering by inducing the shoot to produce floral buds instead of leaves and lateral buds. Some short-day facultative plants are: [16] Kenaf ( Hibiscus cannabinus) Marijuana (Cannabis) Cotton (Gossypium) Rice (Oryza)
Cannabis (/ ˈ k æ n ə b ɪ s /) [2] is a genus of flowering plants in the family Cannabaceae that is widely accepted as being indigenous to and originating from the continent of Asia. [3] [4] [5] However, the number of species is disputed, with as many as three species being recognized: Cannabis sativa, C. indica, and C. ruderalis.
Cannabis ruderalis is a variety, subspecies, or species of Cannabis native to Central and Eastern Europe and Russia.It contains a relatively low quantity of psychoactive compound tetrahydrocannabinol (THC) and does not require photoperiod to blossom (unlike C. indica and C. sativa).
The flowering phase varies from about 6 to 12 weeks for pure indicas with their shorter flowering time than pure sativas. Mixed indica/sativa strains have an intermediate flowering time. The sex is clearly revealed in the first phase, the actual flowering. Males produce little ball-like flowers clustered together like grapes called panicles.
