As with any cannabis strain, an autoflower worth its weight needs to produce decent yields of flower with a strong structure, plenty of potent resin, and a mouth-watering aroma. Thanks to the hard work of cannabis breeders, today's autoflowers are capable of just that—and even more. In this article, we'll shine a light on the best autoflowering strains currently on the market. Regardless of your skills or how you choose to grow, these 10 specimens deserve a place in your garden.
If you still have doubts about the potency of autoflowers, toking on Gorilla Glue Autoflowering will put them to rest. Originally created as part of a breeding "accident" by Joesy Whales and Lone Watie, GG has become arguably one of the most popular cannabis strains on the planet, largely due to its incredible potency. Now, growing and enjoying this renowned strain is easier than ever before, thanks to the creation of Gorilla Glue Autoflowering.
It takes just 9 weeks for Gorilla Glue Autoflowering to grow from a sprouted seed into a bulky bush loaded with frosty flowers. During this time, she'll grow to 60–100cm tall and develop sticky, dense flowers with up to 24% THC. When it's time to light up, Gorilla Glue Autoflowering will hit you with a strong cerebral euphoria quickly followed by a creeping couch-lock. Her aroma is dominated by pine and citrus notes, accentuated with hints of sour fuel, while her taste is sweet and lemony.
The name Northern Lights is bound to prick the ears of many indica connoisseurs.

Meanwhile, her effects instantly put the mind at ease and relax the entire body, making her ideal for smokers wanting to unwind and recharge.
Amnesia Haze is a true Dutch coffeeshop classic. With her mind-boggling, almost psychedelic effect and iconic aroma, it's really no wonder this strain has left the legacy it has. The only downside to Amnesia Haze, as with most Haze varieties, has always been her long flowering stage and large stature. Luckily, with the creation of Amnesia Haze Autoflowering, those troubles are now in the past.
Reaching a maximum height of roughly 150cm, Amnesia Haze Autoflowering is perfectly suited to indoor cultivation in small tents or rooms. Meanwhile, her 11-week life cycle (that's right; this Haze takes just 11 weeks from seed to harvest!) makes Amnesia Haze Autoflowering ideal for outdoor gardeners working with short growing seasons. Come harvest time, she will reward with large, elongated flowers boasting a rich, sweet lemon aroma with those iconic hints of pepper, spice, and earth. And just like the original, Amnesia Haze Autoflowering produces an uplifting euphoria that's perfect for early mornings or daytime sessions when you need to stay productive, focused, and motivated.

She has won countless accolades at cannabis cups across the globe, and, thanks to this new autoflowering recreation, could become the hottest addition to your tent, room, or outdoor cannabis garden yet.
Zkittlez Autoflowering is typically an indica-dominant variety, like her photoperiod predecessor. She takes 11–12 weeks from seed to harvest, taking roughly 4 weeks to veg followed by an 8-week flowering phase. During bloom, Zkittlez develops thick indica-style buds with a heavy coating of aromatic resin. Pick her apart in a grinder, and you'll be seduced by a strong candy aroma dominated by hints of sweet berries, cherries, and tropical fruits. After just one hit, Zkittlez Autoflowering will lull you into a deep state of relaxation before sending you off into a deep, restorative slumber.

Mazar is a beloved strain born in the hilly regions of north Afghanistan, where specimens can grow up to 4m tall and produce immense amounts of dense, delicious flower. Given its origins, Mazar can hold up to cool climates and is naturally resilient to many pests and pathogens. Auto Mazar takes the potency, flavour, and high yields of the original Mazar and combines them with the ease, speed, and manageable stature of an autoflower.
Auto Mazar's full life cycle lasts roughly 10 weeks from seed to harvest. On average, plants grow to just 70–80cm and produce a thick central stem with a few side branches.

Looking for a CBD-rich auto? Then this is it! Stress Killer Automatic CBD is a unique hybrid with a stable 1:1 CBD:THC ratio. The original feminized Stress Killer CBD combines genetics from Juanita la Lagrimosa (a fruity CBD strain) and Lemon Shining Silver Haze (a cross of Lemon Skunk and Amnesia Haze). Stress Killer Automatic CBD, however, combines these genetics with ruderalis.
Stress Killer Automatic CBD takes roughly 11 weeks to complete her life cycle—a little longer than some of the other strains on this list. But the wait is well worth it; depending on how and where she's grown, Stress Killer Automatic CBD can reach between 90 and 160cm, which is exceptional for an autoflower. Come harvest time, her strong branches and central stem will be loaded with heavy, bright green flowers emanating a bold citrus Haze aroma packed with hints of fruit. Finally, her high has to be one of the most balanced we've ever experienced; Stress Killer Automatic CBD is ideal for when you want to enjoy a gentle buzz that boosts the mood and keeps you focused. Light her up in the morning, during the day, or during late-night study/work sessions to enjoy CBD and THC in harmony.
