So where do all the myths from sexing cannabis seeds come from?
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.
5 Tips on How to Sex Marijuana Plants
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.
One of the biggest myths of sexing cannabis seeds comes from a popular chart online.
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.

If you are growing marijuana for medicinal purposes, you need to know how to identify female and male marijuana plants. Almost all growers prefer female marijuana plants because only females produce the coveted buds needed for medicinal purposes. Male plants have low potency and THC content compared to the female plants, and they are kept to mostly produce seeds.
If you’re growing marijuana plants, it’s important to be able to tell male and female plants apart, since only the females produce the buds that contain high concentrations of THC. To identify male and female marijuana plants, make sure they’ve been growing for at least 6 weeks, since both types of plant look the same in their early stages. Then, look for male plants to have thicker stalks and fewer leaves than their female counterparts. You can also tell if a plant is male by checking for little flowers or bulbs at the joints of the stalk and branches. By contrast, you’ll see small, translucent hairs on the same areas of a female plant. Once you’ve identified that a plant is male, remove it from your growing area to prevent it from pollinating the female plants, which will result in your THC harvest being reduced. For tips on what to do with plants that have both male and female organs, read on!
In the colloidal silver feminizing method, distilled water is mixed with pure silver and sprayed on female plants. This method works best when the plants are flowering. This results in pollen sacs being formed, which will allow the seeds to produce female plants.
If you’re looking for more precise, science-based methods to tell your plant’s gender, there are several labs that can sex your plant right after germination – eliminating the lengthy (usually around 6 weeks) wait to learn its gender. Portland, Oregon start-up Phylos Bioscience is in the business of studying cannabis genetics, and they sell a “plant sex kit” that’s pretty simple to do, even for the not scientifically-inclined. Simply press a cotyledon, or embryonic leaf, onto the kit’s filter paper and send it to their lab. They then test the leaf for the “Y” chromosome to determine its gender, just as would happen for a human male.
If you have some experience growing cannabis and would like to bend a crop to your will to ensure that the seeds will be female, there are a few feminizing methods you might try. One such technique is to literally stress out a healthy female plant by interrupting the light cycle during flowering, called Rodelization Feminizing.
What are Feminized Seeds?
How much time you want to spend figuring out the sex of your cannabis plants really depends on how much time and energy you’d like to devote to growing your own marijuana. If you are a medical cannabis patient or caregiver, for example, and need to know what kind of cannabis you are getting every time, buying feminized seeds from a trusted seller is the way to go. But, if you have some time, consider yourself a green thumb, and want to experiment with your grow, you could simply plant your seeds and see what comes up. Happy growing!

While it’s basically not possible to determine the sex of a seed from a random bag of seeds, a practice known as feminizing is becoming quite popular. Feminized seeds are selectively bred to produce female plants, however, some growers do worry about some feminized seeds turning into hermaphrodites.
There are many companies that sell feminized seeds, but, buyer beware, do your research to make sure the seller is reputable, especially if purchasing online. Thanks to modern technology, most feminized seeds from reliable brands will be 100% female as advertised – but that doesn’t mean there aren’t people selling low-quality seeds out there.
