Autoflowering cannabis varieties automatically switch from vegetative growth to the flowering stage with age, as opposed to the ratio of light to dark hours required with photoperiod dependent/short-day strains. Many autoflowers will be ready to harvest in less than 10 weeks
Indoors Purple Haze Auto will produce yields of 400 gr/m2 from plants that reach 60 - 120 cm. tall in a total growing time of 70 - 75 days. Outdoors these plants do not grow any taller than indoors but will produce as much as 250 gr. each.
