Top 10 Autoflowering Cannabis Strains

There are many advantages to autoflowering strains. As the name suggests, they will move into the flowering stage by themselves. They tend to be more resilient than photoperiod strains which require very precise lighting conditions. This is true when it comes to growing in an urban environment. Artificial light will stress photoperiod strains in a way autoflowering strains can withstand. They can also withstand colder climates.
