Autoflowering cannabis strains have become massively popular among weed cultivators. After all, they grow fast, they're beginner-friendly, and with a healthy injection of modern genetics, they're potent and flavourful to boot. They're also great for growers who want to keep their passion project under wraps, as plants usually stay small and compact. In short, there's a lot to love about autos!

With so much to offer, it's only fitting that we shake up the selection of autos available at Royal Queen Seeds and bring you something from every corner of the cannabis world. That means cutting-edge F1 hybrids, timeless classics, and a handful of modern genetics straight from the US. If you're unsure about growing autoflowering cannabis strains or have been disappointed in the past, then let the ten varieties outlined below restore your faith.

Autos are bigger and better than ever, and we can prove it! Whether you opt for traditional autos or next-gen F1 hybrids, get acquainted with the best autoflowering strains to grow in 2024.


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.

Because she descends from pure parent lines, Titan F1 possesses hybrid vigour that results in huge harvests, excellent disease resistance, and higher levels of THC and other cannabinoids.

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%. Throw in a sweet and chocolatey terpene profile, and you have one seriously stoning phytochemical cocktail. Reserve these flowers for lazy afternoons and evenings to enjoy their euphoric effects.

If you’re looking for discretion, then you just found it! As one of the best autoflowering strains for covert growers, this little pocket rocket will churn out up to 500g/m² while remaining at a height of 60–120cm. Prepare to harvest 10–12 weeks following germination.

8. HulkBerry Automatic 

The original HulkBerry pushed the boundaries of cannabinoid production and amazed the European cannabis world with her hard-hitting highs. Royal Queen Seeds managed to capture the best elements of this legendary high in an autoflowering strain.

After crossing HulkBerry with Diesel Automatic, the progeny emerged as a sativa-dominant variety boasting long, tapered flowers with a THC level of 21%. Opening a stash jar full of these buds releases a wave of sweet and fruity terpenes into the air, which gives a hint of the flavours to come.

HulkBerry Auto thrives in a mild climate and does particularly well in grow tents and greenhouses, where she reaches a height of 80–120cm. Indoor plants produce 450–500g/m² and respond well to LST. Outdoor plants offer 100–150g/plant and do well when interplanted with companion species such as basil. You can expect to make the chop just 8–9 weeks after your seeds germinate.

9. Orion F1

The excitement of germinating cannabis seeds quickly wanes as the realisation of the wait ahead takes hold. However, Orion F1 takes the sting out of this thought. This F1 hybrid cannabis seed moves with great speed. After germination, she’ll start shooting upward and pumping out fan leaves to fuel growth. Thanks to her disease resistance, you can rest easy knowing that she’ll stand strong in the face of many types of pests and pathogens. Eventually, she’ll top out at 80cm and start to develop shimmering buds that boast wild trichome density. Overall, you’ll only have to wait 70 days to snip off these buds and load them into your drying rack.

Speed aside, Orion F1 will get you more baked than most autos available on the market. Her high levels of THC, small concentrations of CBG, and fruity terpenes serve up a relaxing and stoning experience. Grab some snacks, put on some tunes, and enjoy the ride!
