What are autoflowering marijuana seeds?
Autoflowering seeds are your ticket to harvests in half the time. These marijuana strains are small, sturdy, fast-flowering, and non-photoperiod . They automatically bloom after several weeks of vegging, finishing their entire life cycle in around ten weeks.
Autos are a favorite among impatient stoners and growers in cold areas. They let you taste test new cultivars after a short waiting period. You can grow two batches per season and cultivate stretchy strains even with limited vertical space. What’s not to love?
Drop the waiting game and fill your mason jars with cannabinoid-rich buds fast. As a bonus, our auto cultivars are already feminized . There’s no need to worry about complicated light setups or males in your garden. Order seeds from i49 and set yourself up for gardening success.
How fast do autoflowering seeds grow?
Fast development is the number one selling point of autoflowering cannabis seeds . Expect your crops to run the entire seed-to-harvest course in short ten weeks . Some sativa strains need more, while indica plants tend to be ripe and ready in as early as seven or eight weeks.
If you’re an outdoor cultivator, autoflowering seeds let you plant two batches of cannabis per season. Alternatively, start late and still collect colas in August or September. There’s no reason to worry about frost and bad weather ruining your harvest.
Indoor growers can maintain summer temperatures all year long. Over a year, these beauties leave you with more buds than you’d get from a photoperiod garden. Mix things up with strains with varying environmental requirements or keep an always-fresh stash of your go-to.
Why do cannabis growers like autoflower seeds?
Autoflowering seeds are ideal for dedicated cultivators of all levels. More people are catching on to the trend and growing non-photoperiod. Why is that so?
The main appeal stands in the name— these beauties flower automatically . You’re never left wondering when to flip the lights or whether your outdoor crops need lamp supplementation.
The non-photoperiod heritage of autos offers further benefits. Ruderalis genetics produces short and squat marijuana plants . There’s no concern about space restrictions for towering sativa or especially aggressive indica strains.
This ruderalis genome originated in central Russia, developing resistance to adverse weather and common diseases . Standard gardening practices get autoflowering marijuana to produce vigorously in response to your TLC.
Like all cannabis varieties, autoflower seeds come with pros and cons. Let’s explore both sides to help you determine whether this is the best option for you.
What are the benefits of autoflowering seeds?
Autos are the top choice of growers with some experience . These cannabis gardeners collect harvests sooner and try new strains before dedicating six months to them. Cool-climate outdoor cultivars and those who always have a fresh stash also go auto.
If you’re reluctant about jumping on the bandwagon, consider the following benefits of auto flowering strains .
- Lightning-fast flowering and harvest
Autos don’t count on long-lasting sunshine and warm temperatures, courtesy of their Russian genetics. Evolution made the growing cycle much shorter , helping crops make the most of their short growing season.
Hybrids combined with ruderalis maintain this growth pattern. Their preferences are strain-dependent, but they develop rapidly indoors and outdoors.
Most autos are harvest-ready in ten weeks. Some cultivars take even less to produce cannabinoid-rich buds.
Photoperiod cannabis goes through life cycles depending on the amount of light outside. Shortening days are its sign to enter flowering, and it’s only then when the bud production commences. Indoors, it’s on you to mimic these conditions and induce ripening.
There’s no worry about light signals with autos.
These crops grow under any light schedule , moving from vegging to flowering. It’s good to keep light exposure high to encourage the bud site, bud, and cannabinoid development. Still, messing up the program doesn’t mean plant stress and hermaphroditism.
Autoflowering seed -grown crops stretch much less than their photoperiod counterparts. There’s more to this advantage than taking up less space in your grow room.
The stealthy stature makes your growing operation much more discreet . We at i49 would never suggest illegal growing, but growers have various reasons for wanting to keep their grow a secret.
Small auto crops blend with other plants in your backyard and don’t stretch to the skies. You avoid nasty looks from landlords and neighbors.
Cannabis produces all cannabinoids, but the market is overflowing with high-THC strains. As a result, high-CBD varieties remain limited unless you shop for strains popular for their CBD production.
This tendency is great for high-tolerance recreational stoners. Medical marijuana users and people looking to tame their high with a non-psychoactive substance find themselves in a bind.
That’s where autoflower seeds come into play. Crops with these genomes are weaker in THC, but they still amp up cannabinoid production. An average non-photoperiod flower is higher in CBD , making the high less aggressive and more therapeutic.
The ruderalis genome originated in barren Russian lands, and crops still developed! They could only do so with excellent resistance to the cold, diseases, and pests . This quality translates to ruderalis crosses too.
It’s much harder to make a mistake with autoflowering seeds . Of course, specific climate and environmental requirements depend on its family tree.
You should always provide optimal conditions, but these marijuana plants remain patient towards rookie errors.
Do autoflowering seeds have any cons?
Plants modified by ruderalis bring numerous benefits, but not all cultivators choose autos. In particular, absolute beginners tend to face issues with these strains . Their short lifecycle doesn’t leave plenty of room to fix any errors you may have made along the way.
Commercial growers and other high harvest-seekers also go photoperiod more often. Let’s discuss why you might skip this variety and choose an alternative.
Autos are smaller in size and able to carry fewer flowers , reducing the size of your overall yield. Of course, the exact figure is different for each strain. You can find quick high-yielders, but in general, you’ll need fewer mason jars for your harvest.
Low yields aren’t unavoidable, though. The right conditions, strains, and growing techniques optimize the harvest potential.
Plant stress stunts development and reduces output. That risk is always possible, but there’s more time to fix the burn or deficiency with long-flowering photoperiods.
It’s a different story if you mess things up with autos. Their short life cycle makes them extra vulnerable to stress . Be careful with lights, nutrients, trimming, and transplanting to avoid damaging your harvests.
Crops increase in potency with time spent in the sun. As a result, those from autoflowering seeds stand slightly lower on the cannabinoid scale.
You can get the best of both worlds by increasing light exposure during their life cycle. This approach requires higher energy expenditure, though.
Powerful lamps that run all day long help the buds fatten and produce cannabinoids. Luckily, the seed-to-harvest period is short enough that you’ll only have to pay higher utility bills for a month or two.
What yield can I expect from autoflowers?
Compared to photoperiods, autos offer small harvests. Autoflowering variants of high-yielding strains produce average harvests.
There’s massive variance between different strains , though. Some autoflower seed -grown crops might yield 3 ounces, while others produce over 24 ounces per plant. If you’re striving for harvest bulk, start with quality genetics.
Get high-yield autoflower seeds in the USA and start there. Combine good genetics with good gardening practices. You can increase the quantity and quality of your harvest and achieve it in under three months.
What gardening practices suit autos best, then? How to take your yields to double digits? Let’s explore two key factors here.
Autoflowering cannabis seeds and the best light for their growing
Cannabis is a light-hungry plant, and that requirement doubles with autos. Your crops don’t rely on the light schedule to start flowering, but they enjoy basking in the sun just the same . Since you won’t have to change your light schedule, which one works best for these crops?
Cultivators keep the lamps on their autos running for 18 or 25 hours a day. The former gives your autoflowering marijuana some downtime, while the latter prompts continual growth. There’s no consensus on which works better, so choose according to what other growers have found success with as a start.
Once you have your schedule down, it’s time to consider equipment. Power savings are a bonus here, but any grow lamp type will do. If you use LEDs, switch the spectrum from blue in vegging to red in flowering.
Our final tip has to do with exposure rather than light itself. Trimming, topping, side lamps, and the Sea of Green technique maximize the amount of light for each bud site. These methods help all flowers fatten, even those on lower levels.
What kind of soil should I buy for autoflower seeds?
You can grow your autoflower seeds in the soil and hydroponic setups. The latter promotes harvest size, but it requires some experience and additional equipment on your end. It’s better to stick to traditional methods and focus on providing optimal conditions if you’re a beginner. How do you do that?
Start by ensuring there are plenty of nutrients in whichever medium you choose. Deficiencies in the short life cycle are bad news, reducing the quantity and quality of the output. Organic soil is an ideal low-maintenance option that guarantees root health and tasty, sticky buds.
Choose an airy medium. Compact soil can constrict the roots , stunting the growth of autoflowering cannabis . You can easily increase aeration by adding coco coir, perlite, or biochar to your medium.
The cultivation environment determines how much your crop eats and stretches. Cannabis can grow in most soil types, but why not go the extra mile? Providing quality goes a long way in improving your harvests.

Even More Great Strains
Outdoor growing can greatly simplify your operation. If you have a safe and discreet location to grow, putting your plants outside allows nature to take care of many of the expensive, time-consuming details for you. You don’t need to purchase and pay to run a lighting set-up. The sun takes care of that. The breeze manages ventilation and the soil and rain feed and nourish your plants. Depending on your particular location, you may need to supplement your plants’ diets with compost or fertilizer, and you may need to water sometimes. It is important to keep the ground moist during the first week until the seedlings germinate. After that most strains will do fine with a good rainstorm once a week or so. For detailed information on growing outdoors check out our outdoor grow guide here. We also have a guerrilla grow guide to help you plan a stealthy outdoor grow, and a description of essential site visits to help you plan out your schedule during the growing season. Also take a look at our Best Outdoor Seeds, and our guide to choosing the right strain for your particular climate.
Why grow Autoflowering seeds?
Autoflowering varieties have been on the receiving end of a lot of abuse since they first came out. They have the reputation of being unreliable, low yielding and producing poor quality bud. But times have changed! With great breeding from a number of reputable seed banks, Autoflowering strains are now ready to compete with their light-dependent counterparts.
A quick review of autos for those of you who are new to this:
Autoflowering seeds contain Ruderalis genetics which make them flower independently of light conditions. Normal Indica, Sativa and hybrid strains require a decrease in day length to trigger flowering. If you are growing outdoors you have to wait until the natural cycle of changing day length sparks flowering to begin in your plants, and hope that it happens soon enough that they can fully develop before the first frosts.
Ruderalis is a wild strain of marijuana which evolved in the northernmost reaches of Alaska, Europe and Siberia. By the time the day length reaches 12 hours of light/12 hours of darkness in those places, freezing temperatures are mere weeks away. Ruderalis evolved a light-independent method of flowering to give itself time to produce seeds before it was killed by frost. Strains that contain these Ruderalis genetics begin flowering after a set amount of time. Typically this is only 2 weeks or so after they germinate.
The benefits for you:
As a grower, using an Autoflowering strain frees you from lighting changes. You don’t have to set your lights to 12/12, you can leave them at one cycle for all your plants, be they vegging or flowering. For outdoor growers, you can count on a harvest by a set date without worrying about changes in light. Autos typically produce much faster than regular strains, so you get a harvest sooner. While some strains still have a lower yield than their regular counterparts, the possibility of multiple harvests with less work makes up for this lack. And let’s not forget, there are many auto strains available with huge yields which can compete with nearly any regular seeds on the market. For the full story on Autoflowering strains, check out our Best Autoflowering Seeds page.
Why grow feminized seeds?
Unless you are trying to produce a new strain or improve the plants you have by selective breeding, you do not want seeds in your bud. Producing seeds takes energy away from THC production, resulting in a lower quality, less potent final product. Typically as plants begin to pre-flower you have to carefully check each one and remove the males, a process which means you lose about 50% of your plants. Feminized seeds have been altered, usually chemically but sometimes by selective breeding, to produce almost entirely female plants. While eventually you will probably be cloning your favorite mother plant to produce future generations of your favorite strain, at some point you will find yourself eager to try a new variety that you must begin from seed. Feminized seeds can save you a lot of time sexing and give you the most for your money as 99% of your plants should be females. Be sure to use a reputable breeder when you purchase feminized seeds, as some breeders produce less reliable seeds. For a full description of feminized seeds and a guide to our favorites, check out our Best Feminized Seeds.
The whole package…
For the easiest grow possible, choose a seed that combines all the great features of outdoor, Autoflowering and feminized strains. They are out there! Due to their hardy Ruderalis genetics, many auto strains are already a little tougher than your average plant. They can withstand changes in temperature, humidity and feeding more easily than their purebred sisters. Growing an auto variety also makes the stealth aspect of outdoor growing easier. These plants typically are very small, often staying under 2 feet in height. This makes them much easier to hide in a container on your apartment balcony or tuck into your flower garden in the back yard. Pay attention to the seed descriptions however, some autos reach over 4 feet in height in the 3 months of their short life! Combining Autoflowering with feminized seeds and choosing a strain suited for outdoor growing will give you a fast harvest with little input. If you live in a climate with a long growing season, you could plan for multiple harvests by growing autos. In fact, some strains can be grown year round in places where temperatures stay high enough.
