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.
Cannabis strains is a popular name to refer to plant varieties of the monospecific genus Cannabis sativa L.. They are either pure or hybrid varieties of the plant, which encompasses various sub-species C. sativa , C. indica , and C. ruderalis .
Cannabis (/ ˈ k æ n ə b ɪ s /) 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. However, the number of species is disputed, with as many as three species being recognized: Cannabis sativa , C. indica , and C. ruderalis .
The flowering cycle can last anywhere between seven and fifteen weeks, depending on the strain and environmental conditions. When the production of psychoactive cannabinoids is sought, female plants are grown separately from male plants to induce parthenocarpy in the female plant's fruits (popularly called "sin semilla" which is Spanish for ...
The pioneer of this group was Monsieur Crozy of Lyons, France, who started breeding cannas as early as 1862, from stock originally developed by Théodore Année. [ 3 ] [ 4 ] [ 6 ] They are sometimes referred to as gladiolus flowering cannas, but describing flowers as similar to another genus is not encouraged. [ 7 ]
Stoners and scientists disagree on the answer. Some ask for a new system.
All known strains of Cannabis are wind-pollinated [16] and the fruit is an achene. [17] Most strains of Cannabis are short day plants, [16] with the possible exception of C. sativa subsp. sativa var. spontanea (= C. ruderalis), which is commonly described as "auto-flowering" and may be day-neutral.
[19] [20] Cannabis x intersita Sojak, a strain identified in 1960, is a cross between C. sativa and C. ruderalis. [3] Attempts to produce a Cannabis strain with a shorter growing season are another application of cultivating C. ruderalis. [8] C. ruderalis when crossed with sativa and indica strains will carry the recessive autoflowering trait ...
