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.

Check out the best autoflowering strains to cultivate in 2022 below.

1. Royal Gorilla Automatic 

Not long ago, some growers would turn up their noses at those who chose to grow autoflowers. The reason behind this is that early autos simply couldn’t match the yield, potency, and flavour of photoperiodic strains. Today, no one would dare say anything bad about Royal Gorilla Automatic, a dank auto that is more than deserving of the spotlight. This uber-potent lady from the US West Coast is a cross of Royal Gorilla, Royal Cookies, and ruderalis. She has been finely tuned for exceptional performance, beastly potency, and top resin production. Not to mention, she delivers up to 400g/m² of dense bud indoors—all within a short 8–10 weeks from seed.

Royal Gorilla Automatic boasts an impressive 20% THC, so she can deliver a real knockout punch. She starts you out with a happy, heady euphoria that makes way for an incredibly relaxing couch-lock. Smoke (or vape) the girl, and you will taste Diesel flavours with citrus, pine, and fruity notes.

2. Green Gelato Automatic

Green Gelato Automatic represents the new standard for autoflowering genetics. She packs all of the best traits of a high-quality photoperiod strain into a small and easy-to-grow package accessible to novices and those limited by space.

As the progeny of Green Gelato and Cookies Auto, Green Gelato Automatic descends from a prestigious line of THC titans with tantalising terpene profiles. Her tapered, light-green buds pack a massive THC content of 24%, which synergises with earthy and sweet terpenes to provide an energising and motivating head high.

Indoor plants won’t surpass 120cm in height, but still churn out an impressive 375–450g/m². Plants grown outdoors in containers and raised beds peak at 120cm as well, offering a return of 100–175g/plant. Prepare to harvest her aromatic buds 9–10 weeks after germination.

Many growers start to feel those post-harvest blues as the outdoor season comes to a close. However, strains like Triple G Automatic offer hope. When the autumn and winter approach, you have the option of obtaining another harvest within a matter of weeks by switching things up and growing indoors. Many autoflowering strains offer good results in tents and grow rooms, but Triple G Auto really stands out thanks to her rapid growing time, compact size, and ample THC content. Harnessing parent strains Triple G and Big Skunk Auto, our breeders managed to create a quick and compact cultivar that outperforms many autoflowers and photoperiods with a THC content of 20%.

5. Amnesia Haze Automatic 

The original Amnesia is a famous sativa with a cult following. Her euphoric high and unique flavour are the reward for what many would describe as a difficult growing process. Most Hazes need around 12 or more weeks to flower, and their size and nutrient demands can be an issue too. Luckily, Amnesia Haze Automatic by Royal Queen Seeds is here to save the day! This fabulous autoflowering variant does away with the long wait, instead requiring only 80–85 days from germination. Moreover, she will remain at a convenient height of 80–150cm, which makes her very manageable.

Amnesia Haze Automatic provides the same superb heady effect that made her big sister so famous—a high that is as cerebral as it is uplifting. Another highlight is her classic Haze aroma that blends earth and citrus notes to max capacity. As long as you make sure not to overfeed her, growing (and enjoying) Amnesia Haze Automatic will be a breeze.
