Marijuana Life Stages & Gender: Only Female Cannabis Plants Make Buds

Did you know there are both male and female marijuana plants? Yes, marijuana plants show gender, and the sex matters a lot to the grower.

That’s because only female plants produce buds. How do you grow female plants?

Regular marijuana seeds will be 50% male, and 50% female. That means half of the seeds will be unusable as far as growing buds.

One way around this is to purchased feminized seeds online. These seeds are available from all reputable online seedbanks, and the plants produced by these seeds are always female.

You can also make your own feminized seeds, but you have to start with two known female plants.

When do marijuana plants reveal their gender?

Cannabis plants go through two stages of life, the “vegetative” stage and the “flowering stage.”

They first go through the vegetative life stage, which you can sort of consider its “childhood” since the plant is only focusing on growing bigger and taller, and gender doesn’t matter. At the beginning of this stage you usually can’t tell what the plant’s gender is.

However, once the plant is about 6 weeks old, it will usually show signs of “pre-flowers” which will alert you to the gender before the beginning of the flowering stage.

Pre-Flowers usually reveal the gender around week 6 from seed

Otherwise you must wait for the flowering stage

Next, cannabis plants switch to the flowering stage which means they stop growing bigger and taller, and instead spead all their effort growing flowers (the buds we want are flowers!). The flowering stage is like the “adult” stage of a cannabis plant since at this point it’s only interested in adult stuff like growing their male and female parts, then pollinating 🙂 In the flowering stage, plants start growing buds or pollen sacs in earnest. The buds we want are female flowers, so growers generally only want to grow female plants.

Growers Want Female Cannabis Plants – These Produce Bud

Regular Marijuana plants reveal their gender in two situations:

After spending a long time in the vegetative stage – some strains/plants will show preflowers (pistils for girls and “balls” for boys) during the vegetative stage if they grow old enough, even when they are constantly kept under a vegetative light schedule. For example, clones can come from plants that are several years old, so you’ll see a lot of clones have female pistils showing, yet will not continue to flower any more than that until after they’ve been switched to a Flowering (12-12) light schedule

Otherwise, all remaining plants will reveal their gender in the first 1-3 weeks after lights are switched to 12-12, and plants enter the flowering stage of life.

When your cannabis plant is about to reveal it’s gender, what you’re looking for is cannabis “pre-flowers.” These usually show up when the plant is around 6 weeks old from seed, but they always appear once the plant is changed over to the flowering stage.

Male and female pre-flowers look different from each other (though it can be easy to confuse them at first). Sometimes it’s hard to tell which is which at first, and in that case you’ll just have to wait until they develop a few more flowers and it becomes more obvious.

Male Marijuana Plant Pictures

Male plants have grape-like balls which form and fill with pollen. The balls will first show up a week or two after changing the plants over to the flowering stage. If the male is allowed to continue growing, eventually these pollen sacs will burst open and spill pollen everywhere.

Female Marijuana Plant Pictures

Female marijuana plants take a bit longer than males to show their first signs after being changed over to flowering.

Female marijuana plants start showing one or two wispy white white hairs where their buds are going to start forming.

They usually first show up where the main stem connects to the individual nodes or ‘branches’.

If a female plant is kept in the vegetative stage long enough (the length of time varies depending on the strain and conditions), then she will start showing the first sign of female hairs even before you move the plant into the flowering stage by changing the light schedule.

If you see wispy white hairs appearing on your plant like the ones pictured below, then you know you have a female plant.

This pre-flower doesn’t have a pistil sticking out at first, but the shape helps tell you it’s a female plant. If you’re not sure about gender after spotting a pre-flower, it’s a good idea to wait and see for a little while, just to see if a white hair appears (which means it’s definitely a girl)
