Advantages Of Feminised Seeds vs. Autoflowering Seeds For Indoor Cultivation
When cultivating cannabis indoors, considering every aspect, what would be the better option for the grower?
Indoor cultivation of cannabis is growing in popularity mainly due to its ability to produce high quality weed strains in a number of varieties. This is because the cultivation is done by the grower in an indoor growing area where he can monitor the plants carefully and ensure that they reach their maximum potential. It allows growers to have complete control over the cultivation process, acquire full knowledge of the quality of the product and work in the comfort and security of their own property.
While there are a wide variety of seeds available, the most popular ones are feminized and autoflower seeds. Here is a detailed summary of the two:
Feminized seeds refer to cannabis seeds that are specially bred to eliminate male chromosomes so as to produce only female plants. They are also referred to as “female seeds.” Most growers are looking for cannabis buds, which they can smoke, that are present only in the female plants. The feminine cannabis plant produces considerably more working substances such as THC and CBD as compared to the male cannabis plant. While the parent plant could be considered genetically modified, the seeds themselves are completely natural as they are produced naturally through pollination.
Advantages Of Feminized Seeds
- Cultivation of feminized seeds ensures that there are only female plants in your garden which allows fast and simple cultivation of the cannabis plant. It eliminates the unnecessary work of pruning and maintaining male plants that ultimately has to be discarded.
- By making sure that only female plants are produced, feminized seeds ensure that each and every plant is producing cannabis. This ensures higher yield as the available growing space is used in the most productive way possible by eliminating the growth of male cannabis plants.
- Feminized seeds are as good as regular seeds to make mother plants. Moreover, there is uniformity in the products even when production is carried out on a large scale.
- The quality of the feminized seeds can be judged from the number of hermaphroditic plants it produces. Feminized seeds from a reputable breeder are almost 100% free from hermaphrodites.
Autoflowering seeds refer to the seeds that are produced naturally by the cannabis plant through its normal germination. They provide an easy and rewarding yield of high quality cannabis. These seeds produce plants that will change to flowering automatically without the need for change in the light cycle or removal of males. This is good for first time cannabis growers, who do not know how to adjust light cycles. In other words, autoflowering seeds don’t require the same level of complexity of care as the other cannabis seeds in order to yield a bountiful harvest.
Advantages Of Autoflower Seeds
- Autoflowering seeds yield low height plants that require less maintenance making it suitable for growers who carry out cultivation in less than ideal growing conditions, with limited space or for legal growth that carries a plant height limit.
- Autoflowering seeds enable to produce extremely fast, easy to grow cannabis plants with excellent resistance to temperature fluctuations. People that have used autoflowering cannabis seeds have reported that their harvest comes sooner, sometimes two harvests in one summer!
- These seeds are resilient and are capable of resisting mold, pests, and frost because of which they can be grown virtually anywhere almost all through the year as long as it doesn’t become too cold. This ensures reliable, timely crop everytime.
- While THC levels are quite low; CBD content in autoflower strains is quite high, making them a perfect option for medical users. CBD causes the effects of marijuana to be less intense and milder thus eliminating the psychoactive properties of THC.
Which Is Better?
You can expect high potential cannabis from good quality seeds whether they are autoflower seeds or feminized seeds. However, with passing time and experimentation, feminised seeds are being preferred more and more by growers for indoor cultivation due to its ability to produce only female plants thereby making it a simple cultivation process.
Moreover, these days most of the autoflower seeds are feminized rather than regular because although autoflower provides 100% flowering, it cannot be cloned. This means that that you have to buy new seeds every time for growing. On the other hand, in feminized cannabis seeds, you may only buy one seed and you can get as many plants from it depending on your choice since feminized seeds can actually be cloned.
What are feminized cannabis seeds?
Feminized cannabis seeds were first created in the 1990’s by Dutch Passion; feminized seeds give rise to female cannabis plants.
Before feminized cannabis seeds were invented, the only option for home growers was to use regular cannabis seeds , these produce male and female plants in roughly equal numbers. The male plants have to be thrown away to prevent them pollinating the females, which would fill the plants with seeds. Many home growers in the 1980’s & 90’s wanted feminized seeds which would only produce female cannabis plants, but this was widely regarded as impossible, many people had tried and failed.
The introduction of seed feminization means that only half as many cannabis plants need to be grown. This allows the grow-room to be smaller, use less energy and be more efficient In countries where cannabis has not yet been legalized growers prefer to have fewer plants to minimise their risk.

The introduction of feminized seeds has been one of those few discoveries that have genuinely changed the way millions of people grow their own weed. Within a few years feminized seed accounted for around 97% of Dutch Passion seed sales. And as other seed companies learned how to create feminized seeds they saw the same effect – nearly all the customers wanted to use feminized cannabis seeds. Today many seed companies only sell feminized seeds.
Here at Dutch Passion, despite inventing feminized seeds we still sell 15 varieties in regular (non-feminized) seeds even though these regular varieties account for just 2-3% of our sales. Selling regular seeds is a service rather than a profitable business for us, we offer regular seeds for the old-school home growers who still prefer them. And our collection of regular seeds is also a valuable source of original genetics for smaller seed banks who like to select plants for their own breeding projects.

How were feminized cannabis seeds discovered?
Its a question we are often asked. How did we find out how to create feminized seeds? The question had been asked ever since home growing began to appear in the 1970’s and 1980’s. There were many ideas, some people believed that minute differences in the size or shape of the seeds could indicate whether the seed would produce a male or female plant. But like many of mankind’s challenges the real answer came after years of study, research and hard work.
Henk van Dalen formally established the Dutch Passion Seed Company in Amsterdam in 1987 after many years collecting and working with the best cannabis genetics. As well as offering top quality cannabis genetics to the home grower Henk always had a passion to make it easier and more convenient to grow cannabis at home without being an expert.

Three books were to play an important part in Henks work. These were: Mel Frank/Ed Rosenthal`s “Marijuana Grower`s Guide” (1978) and Robert Connell Clark`s “Marijuana Botany” (1981) and Jorge Cervantes “Indoor Marijuana Horticulture” (1983). The comments in Rosenthal’s book about female seed possibilities was especially interesting to Henk who has always looked to make marijuana growing easier and more convenient to the home grower. Henk used his Biology degree and understanding of plant hormones to apply some scientific methods to his work.
Henk noticed something unusual when he left female plants to continue flowering for a few weeks longer than normal. He noticed that female plants grown from regular seed and left to bloom for several weeks longer than normal could produce male flowers at the very end of their life cycle. At the time it was an observation that was puzzling, yet it was also an observation that was repeatable. The male flowers were produced so late that the plant was unlikely to be able to pollinate itself, the optimum point to pollinate a female cannabis plant is after approx. 4 weeks not 12 weeks ++. Henk carefully collected the pollen produced from these male flowers and used it to pollinate other female cannabis plants. The seeds were collected and grown. The process was time consuming but necessary. It was a remarkable ‘Eureka’ moment in cannabis history, all the seeds produced female cannabis plants. At first it seemed too good to be true, it was repeated again and again.
Eventually it was clear that the pollen collected from these late male flowers gave rise to female plants. It was called ‘female pollen’ since all the seeds grew into mature females. Feminized cannabis seeds had been invented and commercially introduced in November 1998. although some people initially refused to believe it was actually possible. The process of collecting this ‘female pollen’ was difficult, female plants had to be grown from regular seed and left for many weeks longer than normal and even then only small amounts of ‘female pollen’ could be collected. Several techniques were subsequently developed to stimulate female plants to create more ‘female pollen’.

Within a few years feminized seed had become the normal way for the home grower to grow their own cannabis. Many people feel feminized cannabis seeds are Dutch Passions greatest contribution to the home grower, but we like to feel that the quality of our traditional, CBD-rich and AutoFem cannabis seeds is an equally important contribution. Henk received the first High Times ‘ Dutch Master’ award for his contribution.
Today feminized cannabis seeds have become the normal way to grow cannabis whether you are growing traditional varieties, autoflowering or CBD-rich varieties. Dutch Passion are extremely proud and grateful to have made a contribution to the cannabis world that has affected the way so many people grow their own cannabis.
10 Most Interesting Facts About Feminized Cannabis Seeds
Feminized cannabis seeds are taken for granted by some growers, but they are still a source of confusion for others, especially for beginners! Here are 10 interesting facts about these feminized cannabis seeds to share with your friends.
Anybody who has ever used cannabis owes their delight to the female aspect of the plant. This is because female cannabis plants contain greater concentrations of the much-loved cannabinoid, THC. For this reason, growers separate male and female cannabis plants to protect the females from pollination. Feminized seeds remove the need for this kind of “sorting”, as plants are basically guaranteed to be female.
- Creating feminized versions of plant seeds did not originate with cannabis, but was a technique used in agriculture for many years before being successfully adapted for cannabis in the 1980s.
- There are several different methods of creating feminized cannabis seeds, but they all rely on stressing a female plant until it becomes hermaphroditic and produces pollen, which is then used to fertilize another female plant.
- When feminized cannabis seeds were first released, there were concerns from some growers that the plants they produced would be unstable hermaphrodites. These fears proved mostly groundless, and as feminization techniques continue to improve, this problem now rarely occurs.
- Feminized cannabis seeds produce feminized, not female, plants, according to the proper scientific definitions. However they are still sometimes referred to as ‘female seeds’. As all the plants they produce should grow and flower like females, it is easy to see how the two names are used interchangeably.
- When feminized cannabis seeds were first introduced for sale, they were more expensive – sometimes much more so – than regular cannabis seeds. Fortunately, nowadays there are many different varieties of good quality, very affordable feminized cannabis seeds available, giving growers a wide range of choice for their money.
- Feminized cannabis seeds grow under the same conditions as regular cannabis seeds and require no special additional nutrients, techniques or equipment.
- The storage conditions required for feminized cannabis seeds are exactly the same as those for regular seeds. They should be kept perfectly dry, at a temperature of between 5 and 7 degrees Celsius, and in the dark. The door of a refrigerator is usually an ideal place.
- Feminized cannabis seeds have advantages for pretty much all growers, but especially for people growing their own medicinal cannabis as they may have less time and energy to spend checking for and weeding out male plants when they begin to appear, as is necessary with regular cannabis seeds.
- There is a misconception about feminized cannabis seeds, namely that they are genetically engineered. Genetic modification describes selective breeding processes that could also occur naturally – Skunk #1 and all other cannabis hybrids could be correctly called ‘genetically modified’. Genetic engineering, on the other hand, is when the DNA of one species is directly infused with the DNA of another – tomatoes with fish genes, for example.
- Sensi Seeds has an ever-growing selection of feminized seeds, in response to many requests from our fans for feminized versions of our most popular and award-winning strains. For some of the most affordable and high quality feminized seeds available online, you can also explore the selection from White Label.
Still curious about feminized cannabis seeds after reading this top 10 list of interesting facts? Great – that’s exactly what we were hoping would happen! There’s a lot more to know about feminized seeds and how they are used to minimise intersexuality. So if your curiosity is piqued, keep reading for some more in-depth information.
Feminized seeds – Breeding to minimise intersexuality
When you purchase a regular cannabis seed, there is a 50/50 chance that the plant will grow to be female. However, under certain stressful conditions, even a female plant can mature and develop intersexual tendencies.
In fact, this forms the basic principle of how feminized seeds were developed. But mitigating these intersexual tendencies is also the objective of developing stable feminized seeds. Sensi Seeds has been perfecting the process of feminized breeding for years now, all so that home growers can minimize the chance of intersexuality in their plants.
Unlike more complex organisms, cannabis is not firmly one sex or the other. It’s a very unusual species in that it is an annual plant that is also dioecious (producing separate male and female flowers on different plants). However, every cannabis plant has the ability to produce flowers of the opposite sex under certain conditions. It’s a survival mechanism for the species, allowing cannabis to succeed and reproduce while being both annual and dioecious.
Some plants become intersexual quite easily, in response to stress in the growing environment such as temperature fluctuations, light cycle irregularity, physical damage, etc. This is a survival response. The plant detects that growing conditions are not favourable, which means that its chances of reproduction are lower. Poor conditions mean that a plant is less likely to survive the full season, and also that there’s less chance a plant of the opposite sex is close enough to cross-pollinate.
In these conditions, some female plants will grow staminate (male) flowers in order to produce their own pollen. They could then fertilise their own pistillate (female) flowers and produce seeds which will grow again the following season. Male plants will sometimes grow pistillate flowers, but this is less common.
10 Interesting Facts About Cannabis Seeds
Old and new methods for breeding feminized seeds
When feminized seeds were first being developed, breeders used two female plants to cultivate feminized seeds. One was identified as having hermaphrodite tendencies (prone to producing male flowers when stressed), while the other did not have this tendency. Light cycle irregularity and pruning were used to stress the intersexually-prone plant into producing male flowers. The pollen from this plant was then used to pollinate the other female plant.
There was a costly disadvantage to this method. As the “pollen donor” was a plant with strong intersexual tendencies, there was a very high likelihood that this tendency was passed on to the subsequent seed.
By the time Sensi Seeds and White Label decided to offer feminized seeds, the process was already infinitely better. Using different techniques, female plants with a very minor tendency to turn intersexual were forced to produce male flowers. This meant that their offspring had no more tendency than a normal female cannabis plant to turn intersexual.
For this technique, there was no need for a female plant that had a strong intersexual tendency, unlike earlier, developing methods. Therefore, the possibility that a plant grown from a feminized exhibits intersexual traits was drastically reduced. This is how the feminized seeds offered by Sensi Seeds and White Label are produced.
In short, intersexuality is a fundamental part of the cannabis genome. Each individual plant simply has a greater or lesser tendency to turn hermaphrodite in response to different conditions. There is unfortunately no way of predicting a plant’s predisposition to hermaphroditism. With that being said, feminized seeds are no more likely to be hermaphrodites than any other seed, thanks to new techniques and technologies.
Laws and regulations regarding cannabis cultivation differ from country to country. Sensi Seeds therefore strongly advises you to check your local laws and regulations. Do not act in conflict with the law.
