  2. Autoflowering cannabis - Wikipedia

    en.wikipedia.org/wiki/Autoflowering_cannabis

    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.
