Top 5 – Fastest autoflower strains

Autoflowers are varieties of weed that don’t depend on specific hours of light or dark to grow and bloom in the same way as photo dependent cannabis varieties. Automatic strains start to flower as soon as they achieve sexual maturity and this can occur as early as 3 or 4 weeks after they have germinated. The genetics come from Ruderalis which evolved in northern Russia, where light conditions are very different to plants originating in the Kush or Latin America.

The fastest autoflowering strains are those that thrive in just 35 days. The issue with these types of cannabis plants is that they don’t have growing time to achieve a good size before they start the flowering phase, so they are often quite small compared to photo-dependent strains. Although if you are growing indoors and have limited space, this negative is actually an advantage!

Nevertheless, it is possible to experience several harvests in a relatively short space of time so autoflowers will always be popular with those who are impatient to reach harvest, especially for those living in the northern hemisphere with cold, short summers. In fact, it is even possible to have perpetual harvests if you plant seeds as soon as one batch starts to flower. Autos also often have better resistance to diseases and extreme weather conditions and are generally considered easier to grow.

1. Santa Maria autoflower

The Santa Maria Autoflower is a true winner in terms of yield as well as having a rapid flowering time of 8 to 9 weeks. Santa Maria is the result of a crossing with Santa Marta, a renowned Brazilian strain with the Colombian Santa Maria. And adding some Ruderalis for good measure. Santa Maria can be grown indoors or outside. Although its resistance to damp, cold and mould makes it challenging in northern Europe, it can thrive if there is enough sunlight. We recommend growing Santa Maria indoors, where you will be amazed at the high-quality yield of this determined little autoflower.

With a fresh, flower and fruity aroma and taste, smoking Santa Maria auto is always a pleasure. It induces attentive, clear-headed and energetic highs that will provide you with intense feelings of euphoria.

2. Gorilla Glue autoflower

The pungent pine and citrus smell of Gorilla Glue Auto is tantalising, and the sight of the super sticky buds will make you eager to get to harvest. Thankfully you won’t have long to wait, as flowering time occurs between 8 to 10 weeks. Gorilla Glue is named after the unusual stickiness and generous quantities of the resin (which makes it ideal for hash production). Still, some also think that it refers to the heavy gluey nature of the powerful stone effects, which can glue you to your sofa thanks to THC levels which are 20- 24%.

Gorilla Glue has become one of the most popular weeds in the world because of its impressive effects. And it is also straightforward to grow -indoors or outside. All we ask is that you plant straight into the largest containers you can get your hands on as she finds repotting stressful. You can look forward to plenty of super-strong and sticky Gorilla Glue ready in ten short weeks.

3. AK 47 autoflower

AK 47 Auto is a fast-flowering strain with buds that are compact, delightfully sticky and emit an inviting aroma. Allow seventy days from germination to flowering. As a typical autoflower, AK 47 is very versatile and can be grown outside, indoors, greenhouses, or even window boxes if space is really limited.

Look forward to repeated harvests in a short space of time, and good quality Sativa-dominant weed that is renowned for its medicinal properties, as well as its pleasantly energetic and cerebral high. Use the glistening resin to make delicious hash.

4. Girl Scout Cookies autoflower

Girl Scout Cookies Autoflower is an Indica-dominant strain that takes the best features of its photo-period parents. The Ruderalis genetics act to stabilise it, and the autoflower is extremely easy to grow and has a notably sweet chocolate minty candy-like taste – one smoke is never enough!

High levels of THC (up to 22%) offer enjoyably euphoric highs and relaxing stones, in the same way as the original Girl Scout Cookies. And it is one of the fastest autoflowers around taking around 55 to 62 days from the seed stage.

The resin of GSC is thick, copious and sticky, making it ideal for oils, hash, and extracts. Girl Scout Cookies autos are 60% Indica which means you can look forward to couch-lockingly heavy stones mixed with euphoric highs that will benefit mind, body and soul. There is also a range of medical benefits, and it is believed to alleviate the symptoms of depression, anxiety and pain.

5. Northern Lights autoflower

Northern Lights Autoflower is a robust and hardy plant that reacts well to any stress or mistakes, so is ideal for novice growers. If given enough space and water, it produces resinous buds which play on your state of mind and cause a relaxing and heavy stone effect which lasts thanks to the presence of a high level of THC and CBD.

The Northern Lights Autoflower can be grown indoors or outdoors, and it grows with great vigour, developing strong, fairly branched stems and many knots in little space, a detail that anticipates its high production.

Its aroma is sweet and floral, of medium intensity and very pleasant. The taste is fruity, with a very sweet smoke from the start to the end of the joint. Its flavour isn’t the most intense but is one with complex undernotes of which you will not tire.

Northern Lights Autoflower is an Indica with all the associated traits; it effectively relaxes body and mind and is soothing and very pleasant. Its effect lasts a long time and can help you sleep. It is a suitable herb for users and patients who need medicinal cannabis with calming properties to treat ailments or aid sleep.

How to make an autoflower even faster?

It isn’t really necessary to force the plants during their cultivation, but if you want weed as soon as possible, there are a few tips that you can put into play. However, it must be made clear that a plentiful harvest cannot be done in a short time, and that production must, therefore, be sacrificed if crop time is to be saved.

One method of accelerating the rate of cultivation is to plant the autoflowering seed in a small pot. When the roots do not have enough substrate, they start to flower to be able to finish the cycle with the nutrients that are available to them.

If you want to harvest a little sooner, you can apply certain products which advance maturation by a few days, both for autos and for standard cannabis strains.

Cannabis cultivators look for specific traits when selecting a strain. Some search for flavour and potency above all else, whereas others are more concerned with speed. Luckily for both the former and latter camps, the breeders at Royal Queen Seeds have dedicated a lot of time to developing top-quality strains that are quick off the mark and rapid to deliver their goods.

Our team has created both fast-flowering feminized genetics and autoflowering genetics to satisfy all types of growers. The former offers all the benefits of photoperiod strains, but with a reduced flowering time.

Our autoflowering varieties, on the other hand, are the fastest in our archive. Infused with Cannabis ruderalis genetics, these cultivars don’t require external cues to flower. Instead, they surge from seed to harvest in a matter of weeks, making them perfect for stealthy home growers.

Let’s explore the fastest RQS cannabis seeds by category. Though the following timeframes are approximations, they are accurate.


Autoflowering seeds can be both sativa and indica. However, they have been crossed with a type of cannabis called ruderalis. This enables them to flower on their own in as little as 2-4 weeks without exposing them to strict 12 hour light regimes.

Some of our most popular strains in this category include:


Quick One is one of the fastest auto-growing strains on the planet. The plant is based on the original auto flowering strain – Lowryder. This strain was created from a cross between William’s Wonder x Northern Lights x Ruderalis. These plants are usually ready for harvest in 8 weeks from germination. The plants also reach between 50 and 60 cm and can yield up to 150g per plant.

Easy Bud received her name for good reason. As well as being one of the easiest cannabis strains to grow, she also boasts one of the fastest growing cycles. Her speedy and robust nature makes her ideal for those seeking a fast turnover, and those ready to take their first step into the world of growing weed.

As the progeny of White Indica and ruderalis, Easy Bud produces frosty flowers featuring a THC content of 12% alongside citrusy and earthy terpenes. These buds won’t blast you to the moon, but they will offer a soothing and subtle effect perfect for any time of day.

Not only does Royal Bluematic offer quick results, but she also delivers aesthetically stunning flowers and relaxing body highs.

Thus, they took the best traits of this classic and made them much easier and faster to cultivate.

After placing her seeds in the soil, growers should be prepared to harvest her bud within a timeframe of 8–9 weeks. Such impressive speed makes her a great candidate for guerrilla growers looking to stay below the radar.

Feminized cannabis seeds are designed to produce only female plants. Feminized seeds will produce a female plant 99.99% of the time. Don’t waste your time trying to produce flower from a male plant – they will only pollinate you females, resulting in seeds rather than bud.

Fast Flowering strains are hybrids of these and autoflowering strains. They are genetically coded to produce flowers quickly with little care, but still rely on a change in photoperiod to flower.

Some of our most popular selections in this category include:


As well as offering a rapid flowering time, Candy Kush Express is a rich source of terpenes, emanating notes of sugary sweet citrus. Her speed of growth and incredible taste make her a great strain for cannabis chefs who want a crop that yields well on a regular basis. This strain features a close balance of 60% indica genetics and 40% sativa, which exerts an effect that relieves tension from the body while keeping the mind alert and functional.

Candy Kush Express is a speedy photoperiod variety that features a flowering time of only 7–9 weeks. Plants grown indoors under good-quality lights will yield up to 525g/m². Those grown outdoors are capable of yielding between 450–500g/plant.
