Autoflowering cannabis strains have grown hugely popular in recent years. They are a great way to get a healthy crop of cannabis without worrying about light cycles. This makes them extremely beginner friendly, and a foolproof way to get started with growing your very first batch of weed.
With autoflowering seeds, you could be harvesting a crop in as little as ten weeks, allowing you to produce multiple grows a year. Autoflowering strains are also great for anyone with limited growing space or time to devote to cultivating marijuana.

However, due to the fine work of autoflower breeders, THC levels in autos are right up there with the strongest feminized strains.
