The best autoflower seed banks of 2025: Reviews and recommended products
Best selection: Seed Supreme
GG4 Auto 4-Pack $55.00
Recommended strain
GG4 is one of the most famous strains in the cannabis world today, and essential growing for cannabis cultivators in the same way that Citizen Kane is essential viewing for film lovers. Seed Supreme’s autoflowering rendition of this famous strain is a fast-growing and low-effort indica-like that is a great pick for either your first grow or your five hundredth. Named after the gloriously sticky resin that it produces in prodigious quantities, GG4 induces a heavily sedating high that relaxes the body, making it a perennial favorite for those who turn to cannabis as a pain reliever or sleep aid.
| • Virtually unparalleled selection of autoflowering strains |
| • Sourced from a global network of breeders |
| • Quick delivery time and regular giveaways |
There’s a staggering number of cannabis strains out there—we oughta know—and the plant’s endless variety is part of the reason why so many people keep falling in love with cannabis. If you have the heart of a collector and gotta grow and smoke em’ all, then Seed Supreme is the bank for you.
They’re a verified weed-seed emporium with dozens and dozens of autoflowering strains available at an affordable price point. If you’ve heard of a strain in a song, movie, or here from Leafly, then the odds are good that Seed Supreme can ship it directly to your door. Our advice? Spend an afternoon browsing Seed Supreme’s vast catalog, you’ll find enough enticing strains to plan out your next several grows & see why they’re one of our best autoflower seed banks.
“You want it? Seed Supreme has got it. We tip our cap to this bank, from one crew of strain fanatics to another.”
GG4 gets its high potency from its heavyweight progenitors, Sour Dubb and Chocolate Diesel. This heritage is also where GG4 gets its polarizing flavor; a heavy punch of diesel and ammonia undergirded by more subtle, sour aromas that make themselves known on the inhale. You can expect your GG4 to have somewhere in the low 20% THC range, plenty for even an experienced consumer with a tolerance to match. Seed Supreme’s GG4 auto is also a cinch to grow, despite the strain’s wide leaves and titanic colas due to the sturdy genetics bred into it by the team at Seed Supreme.
Best for beginners: ILGM.com
White Widow Auto 5-Pack $74.25
Recommended strain
White Widow, a massively popular strain that began to dominate cannabis culture in the mid-90s, is often recommended for newer growers to get their feet wet with growing before diving in. ILGM has made it even easier to grow this famous “it strain” by creating an autoflowering variant that does almost everything but water itself. Even if you’ve struggled with keeping plants alive in the past, ILGM’s White Widow Auto is a cinch to care for, with the ability to thrive in virtually any setup. This strain laughs at cramped apartment closets, fluctuating temperatures, and even some common diseases that make less hearty strains tremble.
| • Wide selection of affordable seeds |
| • Free grow bible emailed to customers with seed purchase |
| • Regular incredible promotions |
ILGM, aka I Love Growing Marijuana, and their incomparable founder, Robert Bergman, have been some of the biggest names in American cannabis seeds through several of the plant’s different eras. As you may have guessed from their name, ILGM is a passion project sustained through a commitment to the joys of cannabis cultivation.
“We’re big fans of their grow bible, a massive tome full of growing wisdom that ILGM sends to your email when you buy any of their seeds.”
And that’s the type of outfit Robert Bergman has made—a company that cares about spreading knowledge and furthering the accessibility of cannabis cultivation.
Like all the best heroines, White Widow’s past is a little mysterious. We aren’t sure of the specifics, but we know that White Widow is descended from a Brazilian sativa landrace and a heavily resin-producing South Indian indica. The result is the Goldilocks of indica-likes, potent but not too potent, relaxing but not sedating, an uplift that comes without panic.
These balanced qualities extend to White Widow’s flavor as well; you can expect a woody, subtly sweet taste that still carries a delightful dankness that our team of writers go wild for. Newcomers to growing and old hands alike will find something to love in ILGM’s White Widow Autoflower, so click the link below and don’t wait another day to start growing.
Best classic strains: Royal Queen Seeds
Amnesia Haze Auto 5-Pack $51.00
Recommended strain
Amnesia Haze has been a mainstay of stash boxes the world over for many years, and Royal Queen Seeds’ autoflowering rendition of this classic is the best way to get it in your grow. Amnesia Haze first rose to prominence in the freewheeling Amsterdam scene, where cannabis’s pseudo-legal nature allowed for incredible amounts of experimentation. Amnesia Haze is one of the standout strains from that process, a citrusy sativa-like that our team loves for a morning smoke that won’t end your day prematurely with overwhelming potency.
| • Deep connection to Dutch cannabis culture |
| • Decades of experience selling cannabis seeds |
| • Online seedfinder helps customers discover new strains |
Royal Queen Seeds is one of the relative newcomers to the US market on this list, but don’t mistake that for inexperience; they only crossed the Atlantic after establishing themselves as one of Europe’s premier sources for autoflowering and photoperiod seeds.
Born in the legendary coffeehouses of Amsterdam, the team at Royal Queen Seeds has had a front-row seat to the development of cannabis into the massive industry it is today. They’re the stewards of some of the genetics from that classic era of experimentation and popularization when Amsterdam was the center of the cannabis universe.
But don’t get it twisted and start thinking that Royal Queen Seeds is just a purveyor of hall-of-fame strains, you’ll also find both new twists on classics and wholly unique strains on the Royal Queen Seeds storefront.
“Cannabis lovers used to have to make a pilgrimage to Amsterdam for this kind of weed. Now, Royal Queen Seeds brings the best of The Netherlands to your garden.”
Amnesia Haze is one of those strains from a shadowy era of cannabis history when genetics and pedigrees get a bit muddled, but it has DNA from both South Asian and Jamaican Landrace strains. Those ancient genetics make Amnesia Haze one of the most recognizable strains on the smoke, but Amnesia Haze is also quite distinctive on the stem as well. You can expect long, thin leaves and foxtail buds with plenty of deep, verdant greens. Amnesia Haze is a bit of a shy one; it takes its time to bloom, but once it does, patient growers will be rewarded with heaps of thick, high-quality buds.
Best expert advice: Homegrown Cannabis Co.
Moby Dick Auto 4-Pack $49.00
Recommended strain
Thar, she blows! Homegrown’s Moby Dick Auto is a true tempest in a teacup, an impressive feat of breeding that has compressed this famously sprawling strain into a much more manageable size. Where the fully-grown feminized version of Moby Dick can dwarf an NBA Center, Homegrown’s autoflowering rendition of the strain only grows to about four feet tall without losing any of Moby Dick’s famous potency.
| • Well-respected growing experts on staff |
| • Large selection of in-house genetics |
| • Significant resources for growers of all levels |
Autoflowers simplify the process of growing cannabis, but any grower worth their salt knows that things can go awry with even the simplest grows. Learning to identify and prevent common cannabis maladies is often the most difficult part of growing, losing your crop to root rot or mites is an experience no one should have to go through. Homegrown Cannabis Co. is doing their part by educating the cannabis growing community by providing free expert knowledge, incredible resources for growers of all experience levels, and providing some of the finest autoflower seeds around besides.
“As fellow weed nerds, we can’t help but admire Homegrown’s absolute commitment to spreading the knowledge of how to grow the good stuff.”
Homegrown’s team of experts is led by the legendary Kyle Kushman, a world-famous breeder and multi-Cannabis Cup winner who has spearheaded the effort to build one of the most significant repositories of growing knowledge you can find online (outside of Leafly, of course).
Everything you need to know about autoflowers, from where to plant to when to harvest, is easily accessible and delivered in a way that makes Homegrown customers feel like they have a personal connection to the masters. They’ve got personalized recommendations specific to the strain you’re growing as well as a 24-7 hotline staffed by experts just in case anything goes wrong. If you’ve got an ambition to grow weed the same way the pros do, Homegrown Cannabis Co. is the seed bank for you.
We aren’t gonna lie to you, Moby Dick Auto can be a bit of a challenge to grow. But the incredible expert community at Homegrown Cannabis has all the know-how any grower will need to make sure your grow is successful. Homegrown has plenty of resources on how to deal with Moby Dick’s unique quirks, and help you grow a powerful plant from your Homegrown Seeds. Their Germination Guide will give you step-by-step instructions on how to shepherd your seeds through the crucial early days, and their 24-7 customer service hotline will help you adapt to any problems that may arise. Together with the experts at homegrown, even growers with very little experience can cultivate this unique, rewarding strain and, unlike Ahab, finally bring home the White Whale.
Most innovative: DNA Genetics
Canelo Auto 5-Pack $80.16
Recommended strain
You may not have heard of this strain from DNA Genetics yet, but trust us, it might be everywhere soon. A true indica-lover’s indica, Canelo is a closer that is best saved for the end of the night when it’s time to tune out and turn off. It excels in this role, and we’re putting our marker down that DNA Genetics’ Canelo’s profile will only keep rising as time goes on, and you can grow it and smoke it way before your local dispensary has it in stock with these autoflowering seeds. If you love indicas, or even just next-big-things, then you need to check Canelo out.
| • Two decades of experience |
| • Creators of several famous strains |
| • Reputation for consistent innovation |
DNA Genetics is a legendary bank that occupies a rare and hallowed spot in cannabis-growing culture. They’ve recently celebrated their 20th anniversary, an incredible feat that makes them older than Methuselah in weed years. They’ve stuck around so long by consistently looking to the future and never resting on their quite considerable laurels.
They’re the minds behind several of the most popular strains to arrive since the new millennium, with a commitment to quality that has earned them the respect of breeders, retailers, and homegrowers alike. The odds are good that the next big strain is somewhere on DNA Genetics storefront, so get ahead of the curve and order some exciting autoflowering seeds from DNA Genetics before they’re cool and never let your friends hear the end of it.
“When we’re looking for something avant-garde that’ll set the smoke circle buzzing, DNA genetics is our first stop.”
OG Kush and Strawberry Banana are the direct progenitors of Canelo Auto, a prestigious parentage that makes the strain nothing less than indica royalty. You can taste and smell that heritage as well, both in the kush earthiness and fruity sweetness. These genetics also mean Canelo is a resilient plant that is quite forgiving to novice growers and less-than-ideal conditions, so don’t let either of those factors stop you from taking the plunge.
You can expect your Canelo buds to have a THC percentage somewhere in the high teens or low twenties, just enough to put you down for the count at night without a trace of grogginess in the morning. Grow what people are going to be talking about before they’re talking about it, and order yourself some Canelo Auto seeds today.
Best high-potency strains: Fast Buds
Strawberry Gorilla Auto 5-Pack $65.00
Recommended strain
Fast Buds’ Strawberry Gorilla Auto is one of the most-awarded autoflowering strains in the world, and it can be yours in no time flat. It recently triumphed in the American Autoflower Cup and even beat out some photoperiod strains to earn honors at the 2023 Farmer’s Cup. Those are some pretty serious kudos to earn, but if you ask them, the team of Fast Buds breeders responsible for this strain would put more stock in the overwhelmingly positive response from growers who have tried their hand at growing their own Strawberry Gorilla Auto. Their hybrid has won hearts with its surprisingly potent strawberry flavor and classic diesel aroma.
| • Autoflower specialists |
| • Winner of several global awards |
| • Quality Californian genetics |
Fast Buds has been on a meteoric rise, quickly rising to become some of the preeminent autoflower specialists in the world. They’re an autoflower seed bank that takes pride in their top-tier California genetics while also maintaining a global perspective on the cannabis industry.
Fast Buds’ trophy case features awards from all over the planet, a truly globe-trotting tour of excellence that we here at Leafly have to applaud (and give our best autoflower seed banks list stamp of approval). As a bank that focuses on autoflowers, they’ve done incredible work in ensuring that autoflowering strains can stand on equal footing in terms of yield and potency to their photoperiod counterparts. They’re an easy recommendation for all the autoflower lovers out there, but if you’re a skeptic who’s made it here, then our advice is to see if the autoflower experts at Fast Buds can change your mind.
“Fast Buds knows the ins and outs of autos better than just about anyone.”
Strawberry Gorilla Auto isn’t for novices in more ways than one. It benefits from an experienced hand that knows how to properly handle its height by providing support and plenty of nutrients. Those growers who are up to the task will reap some truly stunning rewards when their gorgeous purple buds are ready for harvest. Strawberry Gorilla Auto is a monstrously potent strain that can produce buds with up to 28% THC. If you’ve ever been skeptical about autoflowering strains’ ability to stack up to traditional photoperiods, we dare you to give Strawberry Gorilla a try; we won’t even say “I told you so!”

What is an autoflower?
An autoflowering cannabis plant is any breed of cannabis that will flower after a certain period of time, regardless of the amount of light the plant receives. This is opposed to traditional photoperiod strains, which will only flower due to changing light levels, either caused by the changing of the seasons or by a grower artificially lowering the amount of light the plant receives.
Autoflowers tend to be smaller, faster growing, and less potent than their photoperiod cousins, although enterprising growers are doing their best to mitigate this last point. Since autoflowers are categorically easier to grow than photoperiod plants, they’re very popular with newer growers who aren’t eager to deal with changing light levels.
All autoflowering strains share some DNA with the cannabis ruderalis plant, a variety of cannabis native to harsh northern climates, forcing the plant to evolve in ways to cope with the lack of sunlight and short growing seasons. Ruderalis isn’t very potent on its own, but breeders can cross cannabis ruderalis with traditional indica or sativa strains in order to produce a plant that flowers automatically, or an “autoflower.”
Pretty cool, right? If you’re still curious about autoflowers, cannabis ruderalis, or anything else having to do with growing cannabis, then head over to Leafly’s guide to growing marijuana. It’s the best spot on the internet to learn everything there is to know about cultivating & harvesting our favorite plant after you’ve made your picks from our best autoflower seed banks list.
