Cannabis plants have evolved enormously over the past couple of decades, mainly thanks to human kind. We’ve spent years combining different species from all over the planet. Every strain has its own specific characteristics, such as structure, type of buds, flavor and effects. When you combine male and female weed plants that are different strains, the new creation takes on characteristics from both, allowing us to create totally new plants.
Male plants essentially produce pollen which is needed for cannabis plants to naturally reproduce; seeds occur when there are male plants in the mix. If you want to make your own seeds you will need a male plant However, if you’re growing regular plants and want to harvest flowers, we recommend getting rid of any males as soon as possible. You won’t be able to tell them apart until they begin to flower, which is when plants begin to show their sex. Male weed plants grow “balls” that open up to let their pollen out, ending up looking like a small bunch of flowers. You’ll need to get rid of them way before this happens. If they manage to release their pollen it’ll be too late. They can take up to three weeks to burst. If you’re still not sure how to tell them apart, male flowers do not have any pistils on them at all.
What’s the difference between male and female weed plants?
Hermaphrodites are a type of plant that contains both male and female flowers, so they will produce buds but they will also pollinate those buds and the rest of your plants. Plants may naturally become hermaphrodites or be turned into one due to stress. Both female and male plants can turn. Thai strains are more genetically inclined to become hermaphrodites, although any strain can turn when stressed enough. There are many factors that can stress out your plants and end up turning them, such as extra light when they’re supposed to be in the night cycle, too much or not enough water, certain insects or pathogens, watering with cold water, or even a badly done transplant. Hermaphrodites aren’t the best type of plants to keep around, as they can produce buds but it’s definitely a risk because they might pollinate the rest of your plants. We recommend getting rid of them; it’s not worth it just for a little bit more weed.
Female plants are basically what everyone is after when growing cannabis, as these are the ones that make buds, which is the part of the plant that contains the most THC. With just one male plant and a miniscule amount of pollen, your plants might end up filling their flowers with seeds. If you have male and female plants in the same growing area, the buds grown there will only produce seeds so you won’t be able to smoke any of it. You can tell females apart due to the fact that their flowers don’t fully close, they’re actually quite open and they produce little hairs called pistils. They’re incredibly easy to recognize, as the first thing they produce are their pistils, which male plants do not have at all.
One of the biggest evolutions has been the appearance of feminized plants; after years and years of work, cannabis plants can be created to have a 99% chance to be female. You need to know how to tell male from female plants when growing regular seeds, as you’ll only get actual psychoactive weed from the female flowers. Male plants pollinate female plants, which fills their flowers up with seeds so if you’re looking to make the most of your plants you’ll want to keep them away from each other. Hopefully we can help you to tell the difference between male and female weed plants by the end of this article; it’s not that hard, but if it’s not explained correctly it can be a bit confusing.
However, when growing marijuana indoors, a marijuana gardener will have to “fool” their plants into thinking winter is coming to induce flowering and kickstart the creation of buds.
You get marijuana plants start flowering (making buds) by changing your light schedule to 12-12.
Tactic 2: Taking a clone and flowering it
After 2-3 weeks of the 12-12 light schedule, most marijuana plants will reveal the first signs of their gender (they either are a female plant and start growing buds, YAY! or they are a male plant and start growing balls, NO!).
Marijuana plants should reveal the first signs of their gender within 2-3 weeks after being changed to 12-12.
Pre-Flowers usually reveal the gender around week 6 from seed
Sometimes it takes a day or two for a female pre-flower to release her first pistil, and the female calyx can look like the beginning of a pollen sac. Generally the more “pointy” ones tend to be female, but sometimes you have to wait and see a few more flowers to know for sure.
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.
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 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.
Common myths on identifying the sex of a cannabis seed
MSNL Team / 19th July 2018
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 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.
So where do all the myths from sexing cannabis seeds come from?
