Things You Must Know About Gender in Cannabis Plants

Reading time: 3 minutes

Plant reproduction is a fascinating thing, particularly when it comes to cannabis plants. When you decide to start growing, you are going to need to know some things about gender when you’re growing your own cannabis. Much like humans, plants are fairly gender fluid.They can be male, female, or hermaphrodite (exhibiting both male and female characteristics). It’s important for you to know how gender affects your growing process. 

Look Between the Legs

Not to be crass, but the best way to determine the gender of your cannabis plants is by looking at what grows between the nodes, aka the area between the stalks and stem of the plant. If you see a pollen sac, which looks like a sac and dispenses pollen, then you have a male plant. Female plants come with what is called a stigma, which catches pollen. When you look at it this way, plant reproduction is pretty similar to mammal reproduction.

Gender is 50-50

Seeds are either male or female, so you have a fifty fifty chance of getting female seeds which will grow into beautiful plants that will yield lots of delicious sticky buds, or male seeds which will not produce any buds. The best way around this is to purchase feminine seeds from a respected seedbank. You can find many good seedbanks online.

Cannabis Plants Reveal Their Gender Before Flowering

Contrary to popular belief, cannabis plants actually reveal their gender before they flower. Cannabis plants have two stages in their life cycle: vegetative and flowering. During the vegetative stage the plant is still young, it is growing, but not budding. At week 6, the plant enters what is called the “pre-flowering” stage. This is when you can begin to see precisely what will be growing between your plant’s nodes.

Some Plants Have More Than One Gender

Some plants are reveal themselves to have more than one gender, i.e., hermaphrodites. This means that they grow both male and female flowers. For obvious reasons, you don’t want hermaphroditic plants when you’re  growing cannabis. You will not only yield fewer buds, but they will be lower quality too. Some strains are much more likely to produce hermaphroditic plants than others, but stressors in your growing environment can also cause your plants to become hermaphroditic. One positive outcome from hermaphroditic plants is that they produce a large quantity of seeds, which is great when you need more seeds for growing. It’s not so great when you’re growing a crop to sell or smoke.

Male Cannabis Plants are Useful

Despite what you may have been told, male cannabis plants are not completely useless. Obviously if you are growing a crop to smoke or sell, then you want females. If you’re growing for the purpose of making hemp, the male plants make for a softer fiber, which is great for making clothing. Male plants also produce far more seeds, which you need to grow more plants.

  1. So do I just get rid of the male plants and just keep the female or I’m not understanding how are you get the female plants to start budding

  2. Dennis…correct me if im.wrong but im.pretty sure it’s the males tjat peoduce seeds…and pollinate the female. Which I think you don’t want that to happen..

  3. Male plants only produce pollen. The females produce the seeds. And the seeds will be varied sexes

  4. Hii all,
    on the subject of seeing your plants.
    There is an old wives tale on how to tell the sex of the baby whilst still in the womb.
    You get a long hair of the expecting mother. thread it through a gold ring and hold above the stomach. If it’s a girl the ring will swing in a circular motion. If its a boy the ring will swing straight forward and back.
    My wife abd I have been doing this for years as a party trick and is right 90% of the time.
    One day I decided to try it out on some seedlings and it worked. So I thought I would go one better and try it on some seeds and low and behold it worked.
    like I said it’s not 100% bur dam good results for me. Better to pull out one or two males rather than 10 or so.
    Give it a go you’ll be amazed.

  6. i have three strains of weed. One is a cotton candy clone which is growing good and is getting close. I germenated seeds . Its obvious there are two strains. The healthiest and most rapid growth strain might be hymorphadite. It looks like i get a set of balls but it turns into another leaf.Am I wrong or is it too early since its only about 2 months old!

  7. do male plant only produce male seeds or do male plants produce male and female seeds i dont know im a beginner
