 Feminized Cannabis Seeds

What are feminised cannabis seeds?

Feminised marijuana seeds are developed exclusively to produce female plants, unlike regular seeds, which can produce male plants in a normal 50:50 ratio.

Do feminised seeds always yield female cannabis plants?

Yes. Growing with feminised seeds guarantees every plant in your grow will be female: no risk of pollination, no time wasted removing males, and 100% of your space working for you from day one.

Where do feminised marijuana seeds come from?

In the late 1990s, the most pioneering seed banks discovered how to produce seeds capable of generating female plants with 99.9% certainty. What was once a revolution is now the most popular choice among growers worldwide.

What are feminised seeds and how are they made?

Unlike regular seeds, feminised seeds contain only female chromosomes. They are not genetically modified, they result from breeding techniques that cross two female plants by reversing the sexuality of one, causing it to produce male flowers with exclusively female DNA.

Can feminised seeds produce a male plant?

With quality feminised seeds, practically no. Early production had some genetic instability, but modern breeders have refined the process to optimal stability levels. At Seedstockers we guarantee high-quality feminised seeds with vigorous, healthy plants and consistent harvests.

Do feminised seeds always produce female plants?

Yes. These seeds contain no genetic code for male sex development. Cannabis can reverse its sex under extreme stress, excessive heat or light pollution during dark periods, but with proper growing conditions this is extremely rare with well-bred feminised genetics.

Why does hermaphroditism occur and what should you do?

Hermaphroditism is a survival mechanism: when a plant senses it can't complete its cycle, it develops both male and female flowers to self-pollinate. Look out for banana-shaped pollen sacks appearing next to buds. If you spot them, remove the plant immediately before it releases pollen and ruins your harvest.

What's the difference between feminised and autoflowering seeds?

Feminised photoperiod seeds depend on the light/dark ratio to flower. Outdoors, this happens naturally after the summer solstice. Indoors, you control the cycle: 18/6h for growth, 12/12h to trigger flowering, between 8 and 12 weeks depending on genetics.

Type of seedFloweringBest forMain advantage
Feminised SeedsDepends on light cycleGrowers who want control and productionFull control over size, shape and yield
Autoflowering SeedsFlower automaticallyBeginners and fast growsShorter cycle and simpler management
Regular SeedsMale or femaleBreeders and genetic selectionUseful for crosses and preservation

This gives you total freedom of planning: you control the size, shape and duration of the cycle. Autoflowering seeds, by contrast, flower automatically in 60-80 days regardless of light cycle, simpler but with less room to manoeuvre.

Why are feminised seeds better?

No male plants.You use 100% of space and resources on flower-producing plants.
Genetic stability.Strong, stress-resistant plants that adapt to different growing techniques.
Full controlYou decide when and how long each phase lasts. More margin to recover from the unexpected.
Real savingsNo germinating, monitoring or removing males: all time, space and money goes 100% into your harvest.

Other benefits of autoflowering seeds

In addition to their speed, which allows for the cultivation of several crops in the same season, autoflower cannabis plants exhibit other equally surprising traits. For instance:

But… What are feminised seeds and how are they obtained?

Unlike regular seeds, which contain male and female chromosomes in their genetic code, feminised seeds only contain female chromosomes, and therefore can only produce female plants.

This peculiarity doesn’t derive from genetic engineering (these seeds are NOT genetically modified) but is instead the result of breeding techniques whereby two female plants are crossed, which reverses the sexuality of one of them to produce male flowers with female DNA.

Can feminised seeds result in a male plant?

During the first few years of production, some of the feminised seeds tended to develop hermaphroditism, which is one of the main enemies of marijuana growers. This was due to the genetic instability and sex reversal techniques of the female plants.

Over time, the different techniques have been significantly improved and feminised seeds have acquired optimal levels of stability. Thanks to the meticulous work of the best breeders, Seedstockers can guarantee that you will be purchasing high-quality feminised seeds with great genetic stability. These are strains with which you can grow healthy and vigorous plants that will lead to first-class crops.

Do feminised seeds always produce female plants?

The answer is YES. As we have previously explained, these seeds don’t contain any genetic code for the development of the male sex. However, cannabis is a dioecious plant that can reverse its sex under certain conditions, for instance in very high temperatures. Therefore, despite the extensive breeding work that has been carried out to remove this trait from the genetic pool of our strains, this could still happen but only on a purely anecdotal level. Hermaphroditism in feminised seeds that have been created after extensive breeding work is so incredibly unusual that it is considered extremely unlikely to occur.

Why does hermaphroditism occur and what to do?

There are several reasons that may cause a cannabis plant to reverse its sex, which is when a feminised strain develops sacks of pollen. In general, occurrences of hermaphroditism (which today are only isolated cases) can be attributed to stress factors like excessive heat and genetic instability. It is also important to pay attention to the light cycles: if, for instance, the plants are exposed to light pollution during the period in which they should be in absolute darkness, that could be a crucial stress factor that could result in this rare phenomenon.

Essentially, hermaphroditism has the function of perpetuating the survival of the species. When a cannabis plant feels that it may not be able to finish its life cycle (i.e. it may not be able to develop flowers and have them pollinated), it can reverse its sex to create male and female flowers at the same time so it can pollinate itself. This way, the plant achieves its biological function, which is to create seeds that will germinate the following spring.

Whilst this mechanism may be fascinating in botanical terms, it would definitely be a huge inconvenience if it happened in your grow. To avoid unwanted pollination, the most important thing is that you detect any signs of hermaphroditism in your plants as early as possible, i.e. that you recognise the male flowers in time before they open up and release the pollen.

You won’t be able to detect whether one of your cannabis plants is hermaphrodite until the flowering stage. During this period you should keep an eye out for any banana-shaped balls that may appear next to the female flowers (i.e. the buds with white ‘hairs’ or pistils). These balls are the male flowers or sacks that contain the pollen.
If you detect a hermaphrodite plant in your grow you need to remove it immediately. Otherwise, as the flowering phase progresses, the sacks will ripen and open, releasing a whitish powder that will pollinate the female flowers and fill them with seeds. This will definitely lower the quality of your crop: nobody wants to find seeds in their buds, as they taste awful when they’re accidentally burned during combustion.

How to prepare the growing medium for autoflowering varieties

Autos require an aerated substrate to help them make the most of the available resources and develop their roots well to accelerate all their metabolic processes. We advise you to work with a substrate that contains 1/3 coco coir and 2/3 peat; or, alternatively, a ready substrate, which you can find in most grow shops. If you’re opting for an organic grow, you can prepare a 'super soil' that contains all the necessary nutrients and microbial life for the entire life cycle of your plants. This will most definitely help you get the best out of them.

Growing techniques for feminised seeds

Seedstockers' feminised cannabis seeds are highly stress-resistant and respond quickly to whatever training technique you choose. If you're an experienced grower looking to maximise your indoor space, our female seeds are the perfect opportunity to work with intensive techniques like SOG, SCROG and LST.

SOG (Sea of Green)

Fill your space with small plants (~30 cm) and develop only their apical buds so they flower evenly. SOG reduces growth time and saves resources, but requires more seeds. Best suited to varieties with a large main cola and little lateral branching: Triton Biscotto Lime Feminised, Super Skunk Feminised, OG Kush Feminised, Amnesia Feminised and Big Bud Feminised.

SCROG (Screen of Green)

Use fewer plants than usual and position a screen or mesh at around 30 cm height. Weave the lateral branches through the mesh to stimulate horizontal branching across the full surface. SCROG requires a longer veg time and careful monitoring. Best suited to sativa-dominant varieties: Wedding Cake Feminised, BCN Critical XXL Feminised, AK420 Feminised and Amnesia Feminised.

LST (Low Stress Training)

Modify natural apical growth by stimulating lateral branch development to optimise light distribution. No mesh needed, just wire and ties to guide the main branches horizontally without causing damage or stress. Ideal for branchy varieties with long growth and flowering times: Moby Dick Feminised or Gelato 41 Feminised.

Pruning techniques: Topping, Fimming, Lollipopping

Topping. Cut the main stem near the third node to promote lower branch growth and a more branched canopy. Ideal for compact, discreet plants.

Fimming. Cut 70-80% of the main stem (not all the way) to generate 4-6 new shoots instead of 2. Maximises top colas without much space.

Lollipopping. Remove lower shoots and secondary branches that don't get enough light, concentrating energy in the upper canopy. Best with single-cola varieties: Amnesia,GG4© Feminised or Super Skunk Feminised.

Growing feminised seeds indoors

In indoor grows you have full control over the photoperiod. Use 18/6h during veg (temperatures up to 28ºC are fine at this stage) and switch to 12/12h to trigger flowering, keep temperatures under 25ºC during bloom. Indica-leaning varieties take around 8-9 weeks to flower; sativa-leaning ones need 9-10 weeks. Remember: plants keep growing during the first weeks of flowering, so factor that into your space planning.

Growing feminised seeds outdoors

Make sure your plants get at least 6-7 hours of direct natural light per day and avoid temperatures below 18ºC or above 33ºC. Germinate in early spring when mild weather arrives.

Mediterranean climates

Germinate from mid-March to late April. Plants grow through spring and begin flowering after the summer solstice, harvesting in late September or mid-October. Ideal conditions for any variety in the feminised catalogue.

Continental or Atlantic climates

Sow in late April or early May, harvest from early September. A greenhouse or shelter is recommended against frequent rains. Choose fast-flowering varieties: BCN Critical XXL Feminised Fast, Cookies Fast or Northern Lights Feminised.

Innovative varieties you'll only find at Seedstockers

If you're looking for something genuinely new in the world of cannabis seeds, Madonna© Triploid is one of those genetics you don't come across every day. Think of seedless watermelon or pitless grapes, similar idea. Thanks to its triploid structure, Madonna© is designed to deliver cleaner flowers with less risk of unwanted seeds and a more stable growing experience.

Madonna© starts from a stabilised Extra Virgin IBL genetic and takes the leap into triploid format. While most traditional cannabis varieties are diploid, two sets of chromosomes, triploid plants have three. In practice, this can translate into more vigorous, more uniform plants with stronger development from the start.

But the most interesting part isn't just stability. Madonna© Triploid also stands out for its rich terpene profile, its great aromatic expression and superior resistance to pests and stress compared to many traditional varieties. For the demanding grower who already knows feminised seeds and wants to try the next step in cannabis genetics, Madonna© Triploid is a serious contender.

And if what you're looking for is outdoor genetics designed from the ground up to survive and thrive in the most challenging climates on the planet, Big Yeti© has a lot to say to you.

Big Yeti© is a photoperiod feminised variety (not autoflowering) born from the cross of Early Durban and Sour Diesel. The Seedstockers breeding team spent 4 years selecting the mother plants most resistant to rain, fungi and pests. The process took place in a coastal zone, which ensured the plants naturally adapted to high humidity conditions, short summers and constant sea wind.

The result is a fast-flowering sativa of 8 weeks, with massive yield, a pronounced citrus flavour and an active, stimulating effect. THC between 14-22%, suitable for beginners and perfect for climates like those of the Netherlands, Belgium, Great Britain, Germany, Scandinavia, northern North America or Patagonia. Awarded 1st Prize Best Outdoor at the Highlife Cup.

For the grower who refuses to sacrifice quality because of the climate, Big Yeti© is the answer.
