Yup one you want to set on fire and breathe deeply.
You bought an autoflower so the normal daylength sensitivity genes have been neutralized (by crossing with daylength insensitive Cannabis ruderalis). Bottom line is this plant will likely fully mature in window sill culture (if in Northern clime - you'll need supplemental light during Northern Hemisphere Winter. It doesn't care about daylenght - it just marches on from vedge through flowering. The plant is naturally an annual so it goes through the seed to seed cycle within a year. If this were not an auto-flower (syn. daylength insensitive) plant then you could keep in in vedge by never allowing it to have 12 hrs of dark period per day. Of course you can keep any plant going forever via cloning...
