Top 10 Autoflowering Cannabis Strains of 2020

Those growing cannabis know there are many cannabis strains to choose from. They may grow medical cannabis seeds, feminized cannabis seeds or autoflowering cannabis seeds.

Autoflowering cannabis strains are renowned for their resilience, speed, and overall ease. These traits make them ideal for beginners, experienced growers seeking an easy stash, and those seeking to optimise turnover.

Autoflowering cultivars are predisposed to flower based on age, as opposed to a change in the light cycle. Most varieties surge from seed to harvest in 8–10 weeks and reach a small to medium height that makes them easy to manage and conceal.

Many growers previously associated autos with low-grade weed, and viewed their speed as a trade-off for potency. However, innovative breeders have created a new wave of strains that boast rapid flowering times alongside THC and CBD levels—not to mention flavours—that rival many photoperiod strains.
