Feminized or autoflowering marijuana seeds

Many clients ask us about the difference between feminized and autoflowering cannabis seeds. Just 15 years ago, only regular seeds were sold in grow shops. Nowadays, however, there are many different kinds of seeds, among which feminized and automatic ones stand out.

Main differences between feminized and autoflowering seeds

The main differences between feminized and autoflowering marijuana varieties are summarized in 3 items: morphological, non-visible and cultivation ones:


  1. Size
  2. Production
  3. Leaves shape
  4. Calyx/leaf ratio
  5. Flower density
  6. Pruning
  7. Amount of resin

Not Visible

  1. Autoflowering gene
  2. Resistance to stress
  3. Power
  4. Amount of terpenes and flavonoids


  1. Different photoperiods indoors
  2. Amount of outdoor harvests
  3. Capacity of asexual reproduction in feminized plants
  4. Possibility of keeping mother plants with feminized
  5. Different feeding
  6. Greater hybrid vigour in autoflowering plants

In general they differ quite a lot, but there are seed formats that can be 100% female and automatic flowering, that is, both feminized and autoflowering seeds, but these different points between them are important. Do you want us to go over them more carefully? Then don’t stop reading…

Morphological differences between feminized and autoflowering varieties

Feminized ones, like photodependent ones in general, grow much more than autoflowering ones. This is because auto plants start to flower earlier.

The feminized ones can form different types of leaf, depending on its percentage of indica or sativa it can be wider or narrower, with more or less leaflets. However, automatic strains usually form the typical ruderalis leaf, with usually 5 or 7 leaflets and medium width.

The calyx/leaf ratio in feminized plants is much more interesting than in autoflowering plants in general. Auto plants create more leaves and buds need more work during harvest.

The bud density is usually much higher in feminized varieties than in auto ones, especially in feminized Indica ones.

Feminized varieties can be pruned and molded as much as you want, but with autoflowering varieties, with such short vegetative cycle, it is not interesting to prune them and they can hardly be molded.

100% female genetics produce more resin than automatic flowering varieties.

Non-visible differences between autoflowering and feminized plants

The biggest difference between these two kinds of cannabis cannot be seen with the naked eye. Feminized, like every photodependent plant, accumulate a protein during the night period that regulates the cycle in order to know when to grow and when to bloom. Auto plants lack this protein, instead they have like a life clock that sets the time when they start to bloom, usually about 3 weeks after germination.

Feminized plants are more prone to stress, this is because these seeds come from plants under stress to reverse their sex. Autoflowering plants are very resistant to stress, especially to luminic stress, which does not affect them at all.

Feminized ones usually contain higher levels of cannabinoids, although during recent years auto plants have improved a lot in this matter. Currently we have automatic plants with THC levels above 20%, but generally they are still below the feminized ones.

The content of terpenes and flavonoids in feminized plants is also significantly higher than in autoflowering plants, although it is also true that gradually it is beginning to match.

Cultivation differences between feminized and autoflowering plants

In indoor cultivation it is necessary to change the photoperiod from 18 hours to 12 hours of daily light so that the feminized ones begin to flower. Autoflowering plants can have the same photoperiod of light throughout the entire crop, no matter 12 hours, 18 hours, 20 hours or even more.

In outdoor cultivation the feminized ones have only one growing season, in the northern hemisphere from March to October approximately. With the automatic varieties you can do several crops a year outdoors, as they are not based on the light hours of the crops about 3 months after germination, regardless of the season.

Feminized plants can be cultivated through cuttings, but auto plants can only be cultivated through seeds.

Mother plants of feminized seeds can be saved but not the autoflowering plants. This is because feminized plants can be kept in vegetative growth at 18 hours of light for as long as we want, but automatic plants cannot, because at 18 hours they also bloom.

Autoflowering ones tolerate the overfertilization better than the feminized ones, with the fem it depends on the variety, some eat more and others less. On the contrary all the autoflowering plants tend to eat more and, of course, to support better the nutrient excesses.

Automatic flowering plants enjoy greater hybrid vigour than most feminized plants. This is because auto plants are a crossing between ruderalis and sativas or Indicas, which are different subspecies, and the more distant they are, the greater the hybrid vigour.

Many times we may hear that feminized or photodependent plants are better than autoflowering ones, and that is not the case at all. As we have seen before, each one could be the best according to the situation, so it cannot be said that one is better than the other in general.

Auto-Flower, Fast Version & Photo-Dependent. what’s the difference?

Nowadays we growers are faced with more choices than ever when buying cannabis seeds, which can be a little overwhelming for some of us. It’s not uncommon to find a seed bank offering several different versions of their best genetics, so as well as feminised seeds, we can often find the same strain also being sold as an “auto” and sometimes even a “fast version”. What exactly does all this mean, and why do breeders offer these different options?

Auto, F1 fast-version and photo-dependant seed packs

It’s been well over a decade since auto-flowering cannabis genetics burst onto a market that, until then, had only consisted of feminised and regular seeds. A little later on, in 2013, Sweet Seeds made the first F1 Fast Versions available for sale. Since then, both of these new types of seed have steadily been improved in quality and, as a result, become hugely popular among cannabis cultivators.

Despite this increased acceptance among growers, there’s still some confusion and uncertainty about exactly what makes these automatic and “semi-automatic” plants different from the good old photo-dependent varieties that have formed the basis of cannabis culture for time immemorial. Read on, and we’ll explain the basic differences between autos, fast versions and standard photoperiod plants and talk about some advantages of each type of genetics.

What are Photoperiod/Photo-dependent varieties?

Simply put in general terms, a photo-dependent or photoperiod-sensitive variety is one that will only start to flower when it’s exposed to a photoperiod with around 12 hours or more of uninterrupted darkness.

Photo-dependent cannabis plants can give enormous harvests outdoors

Photoperiod-dependent varieties are the short-day flowering type of cannabis that growers have been cultivating since forever. We can define them as plants with distinctly separate vegetative growth and flowering phases, both of which are fully dependent upon the photoperiod (the light schedule) that they are exposed to. For indoor growing, this means that while we keep the plants under a growth photoperiod they will continue to develop without flowering.

The standard photoperiod used by indoor growers for vegetative growth is 18 hours of light and 6 of darkness. When the grower decides that the plants have grown big enough, the photoperiod is changed to 12/12 to initiate flowering, meaning they receive 12 hours of light and 12 hours of darkness. In outdoor cultivation, this sensitivity to the photoperiod means that the plants will keep growing all through spring until late summer when the hours of darkness are enough to trigger blooming.

Photoperiod plants offer growers greater control over the cultivation cycle, so if we want, we can have very large and productive cannabis plants by extending the vegetative growth stage. On the other hand, we may decide to restrict the final size of our plants by only giving them a very short growth period. In this way, we can tailor the duration and size of our cultivation to our circumstances and adapt to any possible time or space constraints. Another advantage of photoperiod seeds is the sheer range and choice of genetics to choose from, a vast spectrum of varieties that far outnumbers the selection of Autos and Fast Versions currently available.

Features of photoperiod varieties:

  • Control of final plant size
  • Control of crop duration
  • Bigger potential harvests
  • Higher cannabinoid levels
  • Widest choice of genetics
  • Can be cloned and kept as mother plants

Photo-dependent or photoperiod genetics are available as Feminised or Regular seeds. To understand more about how day and night length affects our plants, check out our blog post on the subject: The Photoperiod of cannabis plants grown indoors.

What are Automatic or Auto-Flowering varieties?

Autos or auto-flowering cannabis varieties are plants that will begin to flower “automatically”, regardless of the photoperiod they are exposed to.

Autos are perfect for balconies and terraces with light contamination from street lamps, etc

The best thing about automatic cannabis seeds is the freedom that they offer growers, enabling them to cultivate cannabis outdoors at almost any time of year, as long as the climate allows it. Now there’s no need to wait till autumn to savour your sun-grown buds because they’ll be ready to harvest as soon as 2 months after germination, whatever the time of the year and amount of daylight. This means that, with the correct planning, growers can harvest several crops throughout the season, and enjoy tasty flowers all year round!

But it’s not just outdoors where autos can really shine, they can be grown with excellent results indoors too, where they can be very useful, for example, to fill a space in your veg room or mother tent, enabling you to take an auto from start to finish while the photo-dependent plants around it carry on growing under 18 hours light and 6 hours darkness. You can also increase yields and get big indoor auto harvests by using a photoperiod of 20/4 or even 24 hours light, thus increasing the overall lumens the plant will receive during flowering by 50-100%, with a corresponding increase in potential yields!

Auto varieties inherit their auto-flowering characteristic from a sub-species of Cannabis Sativa called Ruderalis (some botanists classify it as a separate species) that is native to the northern parts of Russia, Central Europe and Central Asia, and found growing wild all across North America. The auto-flowering trait is most likely an evolutionary adaptation enabling plants to complete their breeding cycle during the long days of the short Siberian summer, where short-day plants wouldn’t finish in time for seeds to mature.

Autos are compact and perfect for small spaces (Philosopher Seeds)

These days, autos make up well over 30% of our seed sales here at Alchimia, but when they first came on the market they were looked on as little more than a freakish curiosity, dwarf-sized plants that would start flowering 2-3 weeks after germination and didn’t give much yield. They even gained something of a poor reputation in terms of flavour and effect, early autos not being particularly productive in terpenes or cannabinoids.

Despite this, cannabis breeders saw the potential offered by these genetics and continued their research and development, improving the quality of each new generation to the current point where the flavour, aroma and effect of the end product are almost indistinguishable from photo-dependent flowers. Breeding efforts have also focussed on increasing the size of the plants, so now we can even find XXL Auto versions of our favourite strains which will grow to a very good size, delivering much bigger yields too. How things have changed!

Features of auto-flowering varieties:

  • Flowering photoperiod: up to 24 hours daylight
  • Very fast turnaround from germination
  • Multiple outdoor harvests in one year
  • No need to change photoperiod indoors
  • Perfect for small spaces and discreet gardens
  • Cannot be kept as mother plants

Tips for growing autoflowering cannabis plants

Growing automatic strains is very popular among many growers taking their first steps in the cannabis world. Learn about the needs of autoflowering plants to get the most out of them and achieve the best quality and production, so you can enjoy an easy and problem-free process.

What is an F1 Fast Version?

Fast versions are F1 (first generation) hybrids between auto and photo-dependent genetics, resulting in offspring that are photoperiod-sensitive, but that will mature around 1-2 weeks earlier than their fully photo-dependent parent, thanks to the influence of the auto-flowering trait.

Red Mandarine F1 Fast Version flowering in the great outdoors

These Fast or Early versions are perfect for guerrilla growers who want to ensure that their outdoor crop is safely harvested and hanging to dry as early as possible in the season. With this type of seed, cultivators can have the best characteristics of both types of seed, with the hybrid vigour of photoperiod seeds alongside the ridiculously fast flowering times of automatic plants. This enables outdoor growers to pull off big harvests ahead of the rest, not only beating the bad weather in early autumn but also making sure they keep one step ahead of nosey neighbours, over-enthusiastic police or potential weed thieves, aka rippers.

F1 Fast Versions are also a very interesting proposition for indoor growers because they can be treated just like photo-dependent varieties, meaning that, amongst other things, we can take cuttings of the best examples to keep as mother plants for future crops. We can also control the duration and size of the crop by providing them with as much or as little vegetative growth as is convenient, allowing them to reach the desired size before switching them over into flower. But once we give them a 12/12 photoperiod is when we see the real advantage of their ultra-speedy flowering, as the influence of the Ruderalis genetics mean they will be ready to harvest in 6 weeks for the earliest examples, and up to 8 weeks for the latest varieties, giving growers the possibility of more harvests each year than normal, fully photo-dependent varieties.

As F1 Fast Versions have gained acceptance and grown in popularity among cannabis cultivators, various seedbanks have also worked to develop their own super-fast-flowering strains, for example, Dinafem with their Quick varieties, which, like F1 Fast Versions, combine auto-flowering and photo-dependent genetics in F1 hybrids that finish 7-14 days earlier than their “non-quick” counterparts. On the other hand, Philosopher Seeds have taken a different approach for their Early varieties and, instead of employing Ruderalis genetics to shorten the flowering time, they have used Moroccan landrace genetics. The famously fast-flowering Early Maroc has been used to create early-flowering hybrids of exciting elite strains such as GG4, Gelato and Super Lemon Haze, bringing the normal harvest time forward by up to 2 weeks outdoors!

Features of Fast/Quick/Early Version varieties:

  • Flowering photoperiod: 12/12
  • Extra-fast flowering (6-8 weeks) indoors
  • Shorter flowering by 1-2 weeks outdoors
  • Control of final plant size
  • Control of crop duration
  • F1 hybrid vigour – fast-growing & resistant
  • Perfect for humid climates and shorter summers
  • Similar cannabinoid levels to photoperiod varieties
  • Can be cloned for mother plants

Fast Versions excel when an early harvest is essential

As you can see, each of these different seed types has its own particular niche in the cannabis cultivator’s range of genetic options. Hopefully, our article has cleared up any confusion you may have had about the differences between them and also helped you to decide which of them is the best choice for your own particular circumstances.
