One of the reasons why every gardening enthusiast should try to grow auto-flower cannabis varieties once in a while is, that mostly sativa-dominant varieties are quite hard to grow in the traditional way.
The downside of many traditional sativas is that they need around 12 weeks of flowering, some phenotypes can even take up to 18 weeks. With autofeminized cannabis varieties this problem is solved. It grows from 80-150 cm tall and finishes around 80 days from seed to bud. Like all sativa dominant plants she can be sensitive to feeding, so be careful not to overfeed her.
