Autoflower vs. Feminized vs Regular (Photoperiod): A Easy to Understand Guide
Autoflower, feminized, and photoperiod (regular) are all options you may be confronted with when it comes time to buy cannabis seeds. Autoflowering promises predictable growth, with no need to fuss with light schedules. Feminized seeds promise no wasted space or time sexing out males. Photoperiod (or normal cannabis seeds) are needed for breeding, experimenting and guaranteed rigorous growth.
But is this too much technical cultivation lingo too soon? Every grower has an opinion about what type of seed is best, but it always comes down to growth expectations, space restrictions, and personal opinion.
Here are the basic details on autoflower versus feminized versus old-fashioned, unadulterated normal cannabis seeds. By the end, you’ll have the information you need to make an informed decision.
Autoflowering Strains 101
Autoflowering strains of cannabis have genetics that guarantees flowering on a predictable schedule. Regular photoperiod plants need changes in the day/night light schedule to trigger a transition from vegetative into flower. Autoflower, as the name suggests, will launch into flower at the appointed time, no matter what.
A typical auto-flowering strain will be ready to harvest between 60 to 90 days after germination. Conventional photoperiod varieties take a minimum of 90 days but can run upwards of six or seven months, depending on the environment and cultivator preference.
Why are auto-flowering varieties different? They contain ruderalis genetics. This is a third landrace strain, like indica and a sativa. Thanks to comprehensive cannabis breeding programs, most established and popular strains are available in regular and auto-flowering varieties.
Autoflowering is useful for pumping out several harvests in the same time it would take to grow a single conventional variety. They also grow smaller (perfect for small indoor spaces) and are more predictable in growth rate and pattern. As a bonus, you will be able to sex your plants within roughly 21 days and maintain the same light schedule (18:6) for the entire operation.
According to experienced cultivators, it can be nice to grow a few auto-flowering varieties while you veg out the main regular strains. The small size also works well for Sea of Green cultivation.
The problem with autoflower strains? Compared with their regular counterparts, their harvests are smaller, including bud size and quantity. Many people also feel that even the cannabinoid and terpene profiles are not as good as the normal varieties.
Feminized Seeds 101
Feminized seeds are preselected female seeds. They are photoperiod, not autoflowering, which means you’ll use changes in light to trigger the flowering.
The benefit of spending the extra money on feminized seeds is that there is little to no risk of wasting time on sexing males. According to some reports, regular seeds run the risk of producing a male approximately a third of the time.
For small-scale indoor operations, or those legally capped at a strict number of plants, feminized seeds make a lot of sense. Why waste time and resources raising a male when you can start with already-feminized seeds?
Feminized seeds are a human-made creation. Breeders and seed sellers use colloidal silver or other chemicals to inhibit ethylene production in a female plant before it goes to seed. Ethylene is a hormone produced during flower by cannabis plants. The treated plants result in almost 100 percent female seeds.
Feminized seeds are specialized and are therefore more expensive to produce and, for the consumer, more expensive to buy. But, many growers prefer feminized seeds because they make growing that much smoother.
Still, even feminized seeds come with a risk. The chemical retardation of ethylene production also increases the risk of developing a hermaphrodite plant, which can appear far later than a male. As per one forum post, “The way I look at feminized seeds, simply put they are hermaphrodites in disguise. Yes, you are more likely to produce females yet they still carry the herm gene.”
Regular (Photoperiod) Seeds 101
Regular seeds produced the way nature intended them are photoperiod. They will need transitions in light schedule and will grow both male and female plants. Female cannabis plants produce seeds when exposed to pollen produced by male plants. It’s the birds and the bees, cannabis edition.
There is a long-standing tradition among growers to value the vigour, variety, and purity offered by regular seeds. There are notable differences in the quantity between auto-flowering strains and their regular counterparts, but what about regular and feminized differences?
These differences may be more lore than reality. To be sure, using synthetic chemicals or colloidal silver to produce feminized seeds can pose risks to both the plant and the people, but there are methods of executing this safely these days.
To date, there is no real evidence (scientific or cultivator case study) that indicates feminized seeds show any less vigour, yield or resin production than the regular seeds.
Regular seeds are much cheaper than feminized. Many growers, who have space, may want to take the birds and the bees into their own hands to maintain genetics or breed new experiments. Having male plants around, when done correctly, is a valuable endeavour.
What is Best for Cultivators: Autoflower, Feminized or Regular?
What convinces a cultivator to grow auto-flower versus regular, or feminized versus regular? Often it comes down to cultivation experience, the primary goal for the harvest, and time or space constraints.
Small indoor spaces, growing one round at a time, may want to stick with autoflower strains. Larger operations looking to sell their harvests but need to stick to a specific plant count may choose feminized. Finally, those who love a traditional approach and are blessed with lots of space will likely stick with regular photoperiod seeds.
As always, there are as many opinions on the matter as there are people growing weed.
The difference between regular and feminized cannabis seeds – Which should you grow?
With the general hype surrounding the relatively recent developments of feminized and autoflowering seeds, you’d be forgiven for maybe thinking that regular cannabis seeds are somehow less exciting. You’d also be wrong. Regular seeds contain endless possibilities for growers to experiment with.
In the beginning of Sensi Seeds, and therefore the European cannabis seed industry, a seed was a seed. Now, we use the name ‘regular cannabis seeds’ to distinguish the originals from feminized cannabis seeds and autoflowering cannabis seeds. Both of these types are relatively recent developments when you consider that cannabis has been cultivated by humans for thousands of years.
Regular cannabis seeds are produced when a male cannabis plant pollinates a female cannabis plant. Male pollen is released from ripe pollen sacs and blown by the wind (or carried by the careful hand of a breeder) until it finds the receptive stigmas in female flowers. Pollination results in hundreds, if not thousands, more regular cannabis seeds which will all in turn produce either male or female cannabis plants.
Can you see the difference between regular and feminized cannabis seeds?
Feminized cannabis seeds look exactly the same as regular cannabis seeds, whether male or female. But inside their modest brown husks there’s a crucial difference. Feminized cannabis seeds lack male chromosomes, whereas regular cannabis seeds contain the full complement of genetics that enable them to be either male or female.
This is also why feminized seeds must always be referred to by that name – they aren’t truly female, and therefore cannot be sold as such. Watch out for seeds described as ‘100% female’, as this is nothing more than a marketing ploy!
The main advantage for growers who choose feminized cannabis seeds is that they don’t have to identify or remove male plants which would cause pollination. Unless the gardener desires more seeds, rather than buds, this is an essential part of the cultivation process.
Automatic, or autoflowering, cannabis seeds are even easier. Not only are they feminized, they do not rely on a change in lighting cycles to trigger flowering. So what are the advantages of regular cannabis seeds?
The Difference Between Craft and Commercial Cannabis, And Why You Need to Know
What are regular cannabis seeds used for?
There are two main purposes for regular cannabis seeds, aside from the usual and most common one of simply growing buds.
- The first is breeding. Selective crossings of one cultivar with another has been taking place since the earliest days of agriculture, with all types of plant life. Sometimes this is to maximise the yield of whatever crop the plant produces which is desired by the people growing it; sometimes it’s just for fun and experimentation.
Whatever the intention of the breeding is, it’s best to begin with all the genetic material in order to give the new cross the best possible chance of success, rather than missing the chromosomes that are absent in feminized cannabis seeds.
- The second use for regular cannabis seeds is the one that was, before the advent of feminized seeds, most commonly used to produce crops of uniform cannabis plants without any males among them. This technique is called cloning. Just as with breeding, it’s best done with plants that have their full set of chromosomes, and all the robust qualities that go with that.
From a crop grown from regular cannabis seeds, the best female plants are selected to become ‘mothers’ – so called because with loving care, they can produce potentially hundreds of ‘children’ over the space of several years. The clones that are taken from these mother plants are tiny replicas down to the last scrap of genetic material – including their female sex.
Why do Sensi Seeds still produce regular cannabis seeds?
There are many seedbanks which only carry feminized cannabis seeds. This has become more common as seedbanks themselves have become more common. With the growing awareness (pun intended) of the advantages of feminized seeds, the question of why Sensi Seeds still carries regular cannabis seeds is quite a reasonable one!
The overall answer is simple, and one which anyone familiar with Sensi Seeds will probably have heard before: we want to bring the joy of cannabis to as many people as possible. That’s not limited to simply selling seeds.
We’re confident in our genetics, we’re confident in our service, and we’re confident in our customers. That means giving everyone the broadest range of options possible. This could be taking the simplest route to a crop of buds, which for most people is automatic seeds. But it could be experimenting with creating a unique cross of their very own, using our genetics as the building blocks.
We have quite often been asked if it’s possible to do all the things that can be done with regular cannabis seeds using feminized seeds.
The short answer is, you can try. There’s no reason you shouldn’t attempt to breed, or create a mother plant, using feminized cannabis seeds. However, it’s our firm belief that these practices are more likely to succeed using plants grown from regular cannabis seeds.

I’m a newbie at this – and I’m growing a few different plants.
I am having a blast with all of this fun stuff –
I didn’t know anything about seeds females/ males or feminized and auto flowering until this year.
But I am really enjoying this adventure.
I really like and appreciate your posts and blog for learning new things about all of the different seeds and processing/ cultivation. You have given me some good info and great explanations on the differences between regular and all other seeds – which is definitely good info for a newbie thank you
Thanks for your comment and your feedback.
I’m so pleased you are finding the blog educational, and having a blast learning!
Please check out the following articles which I think you may find of use, and I hope you continue to enjoy the blog!
With best wishes,
Good day hooter heads from around the world from Australia,due to the economic climate from covd & most govt recognising the money in pot,we won’t have to go to such length,s sneaking about like outcasts,the med uses for this versatile plant have saved the day,the war on drugs is a hoax,if it wasn’t the hard drug crops Afghan, Thailand opium would of been eradicated,like south America,s coke industry..I think govt,big corp are scammers.
I like feminized seeds but I have used regular seeds and they both grow just as well and have the same potency. Some people like feminized over regular seeds but it doesn’t make a difference except that you might get a male instead of a female but you can use that male to get hundreds more seeds and cross breed them with other plants and get different types of plants. Thank You.
For breeding for the rare Cannabinoids you really need to use selfing like is used for feminized seed production. I speak from experience being the very first to commercialize using STS, I did not make and sell feminized seeds I bred varieties that had a single Cannabinoid, for each of the less common Cannabinoids, like CBC, CBG, THCV, CBDV, CBCV, CBGV each in very high amounts and with close to zero other Cannabinoids. This can not be done with regular seed breeding. And male genes as found in regular seeds do not produce better plants for growing or breeding, I think maybe you do not understand plant genetics for Cannabis which is a Dioecious obligate outcrosser.
Why no mention of hermaphroditism? That is not only How you breed then but ultimately also the biggest flaw and why producing fems is really polluting the gene pool.
Hermaphroditism should be a recissive gene, but your breeding requires it to be a dominant trait. It’s like finding people with dodgy heart conditions or baldness (typical recessive traits that can skip generations) breeding them so everyone goes bald and has a bad heart.
But hey the market wants what the market so u gotta sell what people buy.
This article is intended for our readers who are new to cannabis seeds and, as the title says, focuses on the difference in results rather than the difference in the techniques that produce the seeds. In previous decades, creating feminized seeds was indeed reliant on finding lines with pronounced hermaphroditic tendencies, but thanks to improvements in breeding technology this is no longer the case.
With best wishes,
Improvements? like what? using silverfiosulphate instead of gibberalic acid?
Im not familiar with this “new” technique that does not require one parent to be hermaphrodite….I read arjens blog but that explains even less.
what exactly is this new technique? how does one create fem seeds without hermies?
FYI selecting strains more resistant to hermie, that require excessive amounts of stress to turn, is not new.
No. the disparition of regular seeds would be a disaster and I don’t understand the Auto flowering for me it’s a non sense, it is my personal opinion.
Fear not, we have no intention of removing regular seeds from our catalogue; they are the backbone of our gene library! Regarding our autoflowering strains, they are of great benefit to people who have limited resources in terms of time, energy, experience, and / or space, for whom cultivating regular or even feminized seeds would be out of reach.
With best wishes,
why dont you sell seeds in Canada.
Thanks for your comment. Unfortunately, legal restrictions on exporting cannabis seeds mean that they cannot be sent to Canada; we wish it wasn’t so, but it is!
With best wishes,
I believe regular seeds Are The seeds. Feminidad and autoflowering Are productos Or decides to Get Buds.
My blessings to tour effort and hope one Day I Will ser My seed baño with My full range Of seeds. We need The cannacopea.
I to agree with the good parts of regular seeds. Also your buds are generally bigger too. Once you have a selection of females it’s time to CLONE!! More fun !
Then one more fun thing is to develop your own breed! Cross your favorite.
I’m just sad you don’t sell to the U.S.. If you change your mind if like to show you some of my cross breeding. And to acquire more seed stocks. Having fun is most important.
Thank you for your comment We wish that our seeds could be sent to the US, but legal restrictions prevent this – as soon as this situation changes, our policies will change too! In the meantime, I hope that you continue to enjoy the blog.
With best wishes,
Long Live Regular Photo Period Seeds.
Did I catch a recommendation to use only reg seeds for a Mother? Please explain. Ive been growing out a FPOG Mother from fem seeds. Will she clone out ok?
Thanks Y’all. 1LUV

Seed Showdown: Regular vs. Feminized
There’s a handful of classic, extra-potent marijuana strains that have been around for a very long time, permanently fascinating both growers and smokers with their superb qualities and eventually attaining the status of legends. Serious Seeds’ AK-47 is one of these outstanding evergreens. For Simon, the owner and breeder of Serious Seeds, finding that unique AK-47 genetic profile was the rare case of the “lucky punch” that every cannabis seed breeder dreams of. Back in 1992, after having already tested thousands of plants from different experimental breeding lines, he finally achieved his goal of creating a high-quality sativa/ indica hybrid with excellent overall properties and its own unique stamp. Thus the legendary AK-47 was born.
Although Simon keeps the exact pedigree of AK-47 a secret (much like the formula for Coca-Cola), he reveals that it was bred from Colombian, Mexican, Thai and Afghan seed stock, resulting in a 65:35 sativa/indica hybrid with predominantly sativa traits.
Over the years, AK-47 has racked up an impressive number of prizes—16!— at harvest competitions worldwide, including in the High Times Cannabis Cup’s hybrid category in 2011. It was also chosen as Strain of the Year in 2003 (HT Dec. ’03). In the form of hashish, AK has yielded major success for Serious Seeds as well—for example, when it took first prize at the 2005 High Life Cup in Barcelona in the hash category.
Simon describes AK-47 as follows: “This easy-to-grow plant is a living legend and our most popular strain. Medium height and produces good yields quite quickly. It has an extremely strong odor (growers, take extra care!) and a long-lasting high. AK-47 plants have a short flowering period for a sativa, producing compact, not-too-leafy buds gleaming with a coat of resin crystals. The name was given not out of any idea of violence, but more in association with its ‘one-hit wonder’ effect. An independent lab test showed 21.5% THC in the samples at the Cannabis Cup in 1999, the highest of all entries that year.”
Simon recommends a five- to 10-day vegetative clone-growth period. AK-47 delivers yields of 350 to 500 g/m2, has a flowering time of 56 to 63 days, and reaches maturity around October 15 under natural light. It has the high calyx-to-leaf ratio typical of sativas, which means lots of flowers and only a few leaves. The single calyx size tends to be unusually large, resulting in fat clusters grouped together very decoratively and densely, contributing to its trademark appearance. These compact nugs ooze copious amounts of glistening trichomes and break up nicely, leaving plenty of resinous crystals on your fingers and unleashing a strong, sweet and fruity aroma. AK-47 is also famous for its outstanding results in hydroponic mediums, as reported by many international growers, and has been very successfully grown outdoors in Spain.
Since last year, AK-47 has been available in the form of feminized seeds. That made the grower known as Mr. Power Planter curious, so he decided to run a test: a head-to-head comparison of both regular and feminized AK-47 seeds. Never before has such a comparison been reported in any magazine, so here it is. Would the feminized AK-47 seeds prove to be as much a contender as their long-established traditional counterparts?
Mr. Power Planter sowed a full package of 11 regular AK-47 seeds and five feminized ones. Germination proceeded very well, and after four days, all of the seeds had sprouted and reached the soil’s surface. From the start, they were grown under three 600-watt Green Bud metal halide (MH) lamps equipped with adjust-a-wing reflectors (without spreaders), so the plants had abundant light to thrive and prosper. One week after germination, they were transplanted into 11-liter containers filled with Plagron Standard soil mix. All 16 plants did well, growing very compactly and with a quick onset of side-branch development and dark green leaves. They were also very homogeneous, both within their group and when the feminized and regular plants were compared to one another.
Three and a half weeks after germination, Mr. Power Planter induced flowering by reducing the light cycle from 18/6 to 12/12, at the same time replacing the MH lights with three 600-watt Osram high-pressure sodium (HPS) lamps. Within 10 days, all of the plants had revealed their sex, with five of the 11 regular AK-47 plants turning out to be males that were then removed. As expected, the five feminized plants presented only female pre-flowers. In the first weeks of flowering, though, it was observed that the feminized plants reacted a bit more slowly to the onset of the flowering period, with the regular plants progressing more quickly into flower production. Other than that, in terms of the overall growth pattern, both the regular and feminized plants still had the same appearance.
Soon, all 11 plants were building very fat main colas and many impressive side tops in addition. The feminized plants were about one week behind in their bud development, but still flowering in a most promising way. A very strong, sweet odor took possession of the growroom, arising from the richness of the massive resin layers on both the feminized and regular plants. All 11 plants were literally oozing with resin as they approached maturity, appearing whiter and whiter with each subsequent week of flowering. The buds consisted of many thick, dense, round flower clusters, rock-hard and chubby—in short, the trademark AK-47 look.
The six regular AK plants were harvested on day 63, just within the 56-to-63-day window promised by Serious Seeds. They produced tremendously fat main and side colas from the bottom to the top, with some of the huge main colas measuring more than 30 cm in length— really big, impressive chunks! The flower structure of these six plants was almost identical, and the same was true for their rich resin amounts.
As for the five feminized AK plants, they did require about one extra flowering week and were harvested after 69 days. They had grown lower than their regular counterparts, measuring from 65 to 85 cm in height only (with three plants about 75 cm), apart from one plant that was subject to a much stronger sativa influence and grew accordingly taller. But the feminized plants’ side branches were longer, for the most part, than those of the regular plants, while their fabulous, fat flower structure and copious resin amounts were equal to them, though with one difference: The side buds—including the lowest ones— were even bigger! Both the regular and feminized plants had the same powerful aroma, sweet but quite mild.
The delicious-smelling, very silver dried buds were of the highest order, a sheer pleasure to look at and smoke. No difference was found between the regular and feminized buds by Mr. Power Planter in terms of odor, aroma and high. While AK is a strain that doesn’t have the most intense taste—it’s a bit mild and slightly sweet, with a hint of a sandalwood undertone, but not especially charismatic—its high proved to be quite a sensation. It was very complex and extremely strong, with clearly pronounced elements from both ends of the cannabis spectrum asserting themselves … at the same time! Under the influence of the AK’s potent indica side, Mr. Power Planter felt like taking a seat, but he simultaneously felt clear and euphoric in the head and didn’t get “hypnotized” or totally blasted away by the indica stone.
Altogether, Mr. Power Planter was stunned by the superb outcome of both the regular and feminized plants. Like many tried and true strains, AK-47 has been often adopted by other seed banks and either used as a component in creating a “new” strain or just flat-out copied. But one thing’s for sure about Serious Seeds’ AK-47: You can’t beat the real thing!
