Difference Between Male and Female Weed Seeds Male vs Female Weed Seeds Plants, like animals, have male and female varieties. The male plants produce pollen which pollinates the flowers of female plants. Flowers that have been pollinated produce seeds. Marijuana, or weed plants, are also either male or female. Female marijuana weed plants that have not been pollinated are called “sinsemilla” or Feminized marijuana seeds can streamline the growing process and ensure that cannabis cultivators get the most out of their hard work. Read all about the process here. Sexing Cannabis seeds has become a hot topic online, but there is no way of knowing if a cannabis seed is female or male by looking at it. Only when the marijuana plant starts to flower will you be able to tell the sex of a marijuana plant. However, there is a cannabis sexing seeds chart floating around on online.
Difference Between Male and Female Weed Seeds
Plants, like animals, have male and female varieties. The male plants produce pollen which pollinates the flowers of female plants. Flowers that have been pollinated produce seeds. Marijuana, or weed plants, are also either male or female.
Female marijuana weed plants that have not been pollinated are called “sinsemilla” or “without seeds.” The flowers are allowed to grow and develop to produce the psychoactive chemical tetrahydrocannabinol (THC).
Weed seeds and plants are cultivated for this chemical. Since only the female weed seeds produce it, growers only cultivate male weed seeds for breeding otherwise they are harvested early to keep them from pollinating the female weed plants.
The sex of the male weed seeds or plants can be determined three weeks before the female weed seeds or plants which are planted at the same time. This is convenient since male weed seeds or plants must be harvested before they can pollinate the female seeds or plants and block their growth.
Male weed seeds or plants grow vertically and do not have as many branches and leaves as the female weed seeds or plants. This causes them to look frail and unhealthy. Instead of flowers they develop small buds that look like balls. These characteristic abnormal growths usually appear between the third and fourth internodes of the main stem of the plant. This is manifested at the start of the development of a male weed seed or plant’s sexual identity.
When female weed seeds or plants start to flower, hairs develop in abundance at the ends of their ramifications. This is not present in male weed seeds or plants. Female weed seeds or plants also develop V-shaped pistils at their flowering stage.
Some weed seeds also develop the sexual organs of the opposite sex. These are called hermaphrodites or “hermies.” Hermaphrodite female weed seeds develop staminate flowers or flowers that have stamens instead of pistils.
Hermaphrodite male weed seeds are not very common since they are not allowed to grow up to their point of ripening when the pistils show. It is important to watch out for hermaphrodites since they can release pollen that can ruin the crop.
They can pollinate themselves as well as the other female weed plants. They tend to pass on their sexual dispositions to their offspring so they are best eradicated. The sex of weed plants can be affected by many factors. Environmental conditions, weed seed age, lunar stages, and chemicals are known to influence the sex of the plants.
1.Female weed seeds or plants produce THC while male weed seeds or plants do not.
2.Female weed seeds or plants produce flowers while male weed seeds or plants produce small buds that look like balls.
3.Female weed seeds or plants develop V-shaped pistils at the start of their flowering stage while male weed seeds or plants do not.
4.Hairs appear on the ramifications of female weed seeds or plants which are absent in male weed seeds or plants.
What Are Feminized Cannabis Seeds?
This article is sponsored by Kannabia Seed Company, an award-winning cannabis seed company headquartered in Spain. Using only the highest quality genetics on the market, their grower-oriented approach has made cannabis cultivation simple and satisfying for growers of all skill levels for years.
Anyone who’s ever savored a joint owes their enjoyment to the fruits of the cannabis plant, but moreover, to the female of the species. That’s because only female cannabis plants produce the cannabinoid-rich flowers that deliver the flavors and effects consumers look for.
This is why many North American growers are turning to feminized seeds—cannabis seeds that carry only female genetics, and can be relied on to produce only female plants. By creatively applying technologies to seed feminization, modern breeders like Kannabia can ensure female genetics in seeds with a nearly 100% success rate.

Cannabis plants that are pollinated naturally or with traditional breeding techniques can produce both male or female seeds. These are known as regular seeds and, as in most species, they occur with about an even split between the two sexes. That means cannabis cultivators starting with standard seeds have about a 50% chance of yielding a female plant from each one.
As a result, growing cannabis from regular seeds isn’t very efficient—it’s akin to running a bakery that has to throw out every second loaf of bread. Growers working from regular seeds have to account for the fact that roughly half of their plants could be males. While those plants are of some value to breeders, folks growing for flower won’t find much to like in them, and too many male plants can spoil a grow.
Traditionally, the solution to this has been an inelegant one, with many cultivators planting at least twice as many seeds as they hope to harvest with the assumption that about half of them will be useless. However big a harvest you’re looking for, using regular seeds means you’ll have to plant twice that many seeds.
Why Grow From Feminized Cannabis Seeds?

There are numerous advantages for growers who start their garden using feminized seeds. By removing the guesswork of germinating regular seeds, feminized seeds streamline the growing process, saving space and time.
That efficiency is key for medical cannabis patients and hobby growers. Since most cannabis regulations limit plant counts, growers cultivating a small crop of cannabis for personal use want to ensure they’re getting the most out of their grow.
Male plants don’t just take up space in a garden, either. They can also sap time and resources from growers. When male and female plants are both present, growers need to cultivate both until their sexes are clear. While some strains will show early signs of their sex before flowering begins, most cannabis plants don’t begin to express their sex until they start to mature past the vegetative stage.
This change occurs when the photoperiod, or amount of light and dark that the plant receives, changes to 12 hours of light and 12 hours of dark. In outdoor gardens this change can happen naturally with the seasons or, in more controlled environments like indoor gardens, by human intervention using light timers.
Once those plants are old enough, growers have to go to the trouble of actually determining their sex, monitoring each individual plant to ensure any males are removed before they can pollinate their female counterparts.
Growers can avoid spending weeks nurturing plants with only a 50% chance of expressing as female and maximize the space and plant count in their gardens by using feminized seeds from suppliers like Kannabia. These specially-treated seeds increase the probability of producing a female plant to 99%.
How Are Cannabis Seeds Feminized?

There are a few techniques that can produce reliably feminized seeds. One classic method is stressing out a healthy female plant by interrupting its light cycle during flowering. While that works to an extent, the more common and controlled method is to spray down female plants with a collodial silver or silver thiosulphate solution. This method makes it possible to control the sex of a plant without any genetic tinkering or modification.
Both substances are a blend of water and fine silver particles, and they work in largely the same fashion. The silver solution impedes the production of ethylene, a hormone involved in flowering. The result is a female plant, but one that produces male flowers with pollen sacs. Since those pollen sacs develop on a plant with only female genetics, female genetics are all they carry. When those flowers pollinate another female plant (one untreated by silver solutions), the resulting seeds are nearly certain to be female.
Treating plants with a silver thiosulphate solution results in seeds that will produce feminized plants nearly 100% of the time, and Kannabia’s breeders have found this method to be the most effective way to maintain the stability of the seeds and future feminized plants.
Feminized Varieties to Try in Your Garden

Can You Tell the Sex of Cannabis Seeds from Their Appearance
Of all the things that can trip a grower up, sexing marijuana plants may just be the trickiest. Sexing plants is so important because growers are typically after the female plants, that produce the huge THC covered buds. Or the medicinal relief that CBD strains can bring. With such opposite effects of male and female plants, it’s easy to see just how important sexing plants is. But what if growers didn’t have to wait to sex their plants? While it would certainly make life easier, is sexing cannabis seeds possible?
Can you determine the sex of cannabis seeds?
This has been a question that has become a very hot topic online these days. After a quick search, growers can find multiple charts and explanations on how to sex cannabis seeds.
Unfortunately, there’s not much truth to any of these interpretations. It’s simply impossible to tell just by looking at them what the sex of any cannabis seed is. If it was that easy, feminized marijuana seeds would not be as popular as they are. People could simply buy regular seeds and look at them themselves.
Typically, marijuana plants cannot be sexed until they have already begun to grow. Cannabis seeds will look somewhat identical and plants in the vegetative stage will also look identical,. As the plants move into their flowering stage, they will start to show very clear signs as to what sex they are. While it would be much more convenient for growers to be able to determine sex before this point. The sad truth is that it’s just not possible.
So where do all the myths from sexing cannabis seeds come from?
Common myths on identifying the sex of a cannabis seed
One of the biggest myths of sexing cannabis seeds comes from a popular chart online.
The chart states that one can determine the sex of a cannabis seed by just looking at them. Within the chart, five cannabis seeds are shown. Three of these are female and two are male, supposedly. This chart says to look for a crater at the bottom of the seed. It explains that females will have a depression that is perfectly round. While males will have a crater that is misshapen and not uniform. However, this is simply not true. The craters found in cannabis seeds have nothing to do with the sex of a seed.
This same chart states that females will also roll easily across a table or surface, while males will not. While it does say that a magnifying glass and pair of tweezers is needed to examine the seeds. neither of these tools will make it any easier to determine the sex of cannabis seeds.
While growers may not be able to determine the sex of a seed, does the environment have anything to do with it? This is something else that has been hotly contested online.
Environment determines sex debate
We know that determining the sex of cannabis seeds cannot be done. However, it’s unclear as to whether environmental factors have any place in determining the sex of marijuana plants.
Research is carried out all the time to determine if a plant’s environment has anything to do with the sex it will turn out to be. And while there’s research stating that it does not, there’s just as much research stating that certain species do have their sex determined by the environment. This same research also states that using certain chemical treatments can also reverse the sex of a plant.
While environmental factors may not necessarily determine the sex of marijuana plants or cannabis seeds, it is known that certain environments can change the sex of a plant.
This will mostly happen when a plant is stressed by its environment. When this happens, the plant may think it’s going to die and as a result, will change itself into a hermaphrodite plant. By doing so, it will be able to self-pollinate itself and survive.
Growers know that hermaphrodite plants can be just as harmful to crops as male plants. Therefore, it’s very important that every grower understand how to sex marijuana plants. Particularly if they’re not using feminized marijuana seeds that will give them only females.
While it would be much easier for growers to be able to sex their cannabis seeds, the simple fact is that there’s no way to do it. However, sexing plants early on during their growth period is not only essential, it’s completely possible. Growers can even do it before their plants enter the flowering stage if needed. Then male plants can be removed and growers can enjoy a nice, full crop.
