Because of the short lifecycle of approximately 2.5 months and their short shape, autoflowering varieties are perfect to grow almost anywhere.
Cannabis Indica and cannabis Sativa respond to changes in the day/night light cycle. According to the hours of daily light, an Indica or Sativa variety will start to bloom. Auto-flowering varieties in cannabis however do not respond to the day/night light cycle. Autoflowering varieties start blooming only in response to age.
