For starters, you can harvest sooner. Unlike regular seeds or even feminized seeds that are constrained to photoperiod [light cycles] – autoflowers will bloom in a set period. Typically, these plants can be harvested between 8-10 weeks whereas regular strains can take more than 4 months. While you can’t keep an autoflower as a “Mother plant” – you can totally use it to consistently clone and maintain a good cycle. Additionally, the short growing period means you can technically get more crops per season.
