After establishing your favourite autoflowering cannabis strains, you’ve mastered cultivating them over several growing seasons. Do you feel like it’s time for something new? If so, check out our best autoflowering cultivars of 2021. These new-school genetics offer huge levels of THC, branch-bending yields, and mouth-watering terpene profiles.
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.

Check out the best autoflowering strains to cultivate in 2021 below.
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.
Growers who don’t mind splashing out on expenditures might choose to run their lights for 24 hours. Some cultivators report more explosive vegetative growth and enhanced yields using this method. Others argue that a 24-hour schedule might deprive plants of their natural resting period.
Growers rarely cultivate pure ruderalis strains outside of breeding operations as these varieties produce very little in regards to yield. However, by breeding successful photoperiod strains with ruderalis genetics, breeders can create autoflowers, and therefore faster, versions of legendary varieties.
The simple lighting demands of autoflowering strains serve as another advantage. As we mentioned above, they don’t require a change in light schedule to begin flowering. This trait allows growers to be extremely flexible with lighting.
SIMPLE LIGHTING DEMANDS
Life Cycle: 8–9 weeks
Flowering Time: 5–6 weeks
What makes autoflowering cannabis different from other types? Well, the key difference resides in the name. Put simply, these strains flower automatically.
Autoflowering cultivars typically reach a height of between 60–100cm. Their compact size and impressive speed enable clandestine cultivators to set up and dismantle their operation in as little time as possible.
For this reason, ruderalis abandoned the strategy of waiting for the seasons to change to trigger flowering. Instead, the subspecies developed an autoflower gene to ensure reproduction before the temperature plummets.
This autoflowering strain is very easy to grow according to sfweekly , both indoors and out, and has an 8 week period from seed to harvest. You can easily create multiple harvests with this, even if you’re not an experienced grower.
As the name suggests, autoflowering seeds will bloom on their own, whereas regular seeds require more encouragement.
The smell isn’t fantastic — they call it “Sour Diesel” for a reason, after all. It’s also a bit bitter, but the aftertaste is quite pleasant.

It will give you cottonmouth, though, so be sure to drink a lot while you’re smoking it. It’s also heavy on the blueberry flavor, which will turn some people on and others off. At 8 weeks from seed to harvest , it’s hard to complain at that convenience.
They’re low maintenance , require little space , and can be every bit as fun to smoke as regular seeds.
Keep in mind that Sour Diesel Auto can also be relatively difficult to grow, at least compared to many of the auto strains on this list. It’s sensitive to mildew and needs powerful lights to grow to its full potential, so make sure you’re a little more prepared for this one.
The flavor isn’t as refreshing as the smell, unfortunately, but that’s a small price to pay for everything else that White Widow can offer.
