How to Tell Female from Male Weed Seeds?

Determining the sex of your cannabis plant is very important. Most growers require female plants because these are the ones that produce the resiny buds we love. Males, by comparison, simply produce the sacs of pollen used to pollinate female strains to produce seeds. Female varieties shouldn’t be pollinated. Otherwise, they will no longer produce their THC-laced resiny buds.

In a regular growing setup, males have to be removed as soon as they’ve spotted to reduce this risk of pollination. Otherwise, you run the gamble of turning your precious resiny buds into seeds and spoiling the whole crop. But can you tell the difference between weed seeds before they’re cultivated?

Can you tell male from female cannabis seeds?

Simply put, there is absolutely no way to tell the difference between male and female cannabis seeds before they’re planted. There is nothing in their appearance or size to indicate what will grow. The only way to tell is to grow it, wait and see.

You can, however, pick up feminized seeds directly from Weedseedsexpress to guarantee a female plant every time. Feminized seeds are bred exclusively to produce female plants. Knowing your seeds are female from the beginning is the perfect solution for hobbyists and smaller setups that can’t waste resources.

If you’d prefer to plant regular weed seeds, experiment and discover the sex of your plant as it grows, you can choose these here too.

Myths about determining the sex from the cannabis seeds’ appearance

There are plenty of myths out there on how to determine if a cannabis seed is male or female. Don’t be duped by them.

One of the most common is that female seeds have perfectly round crater-like impressions under them, just like a volcano. This is false. Crater-like impressions or indents can form on any and all seed varieties, no matter the sex.

Other myths include those pertaining to size and shape. Neither male nor female seeds are smaller or bigger than one another.

What’s more, some have speculated that male seeds are heavier, ragged or protruded, meaning that if you roll them on a table, they thump like a flat tyre. By comparison, it’s supposed that female seeds are smoother and therefore roll easily across a table. This is also false. Any seed can be any shape – it’s got nothing to do with sex.

Finally, there are no other indicators to tell the sex of cannabis seeds. No aroma, weight difference or coloration. If you find a chart indicating such methods of detection online, ignore it. This will prevent you from wasting time cultivating and accidentally pollinating your crops.

What can you do to tell male from female cannabis seeds?

The only way to sex your cannabis seeds is to sow, grow and check. Most female strains begin to show characteristics of their sex after 4 weeks or more, just before the first stage of flowering.

You have to wait out the vegetative stage until the hair-like pistils begin to grow from the stems. This is indicative of the pre-flowering stage and a sure-fire sign of a female plant.

By contrast, male plants show their signs much earlier. Male plants grow sacs within the crevices of stems which are filled with pollen. As soon as you notice these, it’s time to remove them from your crop to prevent pollination. Males typically grow these sacs in as little as 2 weeks, giving you plenty of time to react.

If you’re worried about your crops pollinating without you knowing, there are a few tricks you can use to identify sex early.

Instead of waiting it out and meticulously inspecting your plant, consider placing an opaque black or paper bag over a growing tip on your plant during vegetation. Keep the bag on for 12 hours in a 24-hour period and repeat. This manipulates the light cycle and forces the plant to pre-flower early. You can then check the sex of your plant after roughly 7 days before allowing it to revert.

There are also professional, scientific ways to determine the sex in advanced botanical setups, but aside from mailing off samples to labs, few can try this at home.

Alternatively, feminized seeds provide a more fool-proof strategy for cultivating healthy, resin-producing crops. You’ll have no need to sex your plants early and run no risk of accidentally pollinating your crop.

What Marijuana Seeds Are Female?

As a rule of thumb, you cannot know what sex the Marijuana seeds are by just looking at them. Even Feminized Marijuana seeds are 99.99999% certain to be female. The only way you can find out what marijuana seeds are female is by germination. After two or three weeks, you will see the male or female flowers and this is the only way to know for sure what marijuana seeds are female.

You know what marijuana seeds are female, but why all the fuss?

Feminized marijuana seeds are the “easiest” seeds to grow after the Auto-flowering varieties. Feminized marijuana seeds mean that they are treated to make them female marijuana seeds (hence the name feminized) so that all the marijuana seeds can be used to get flowers. Breeders usually sell feminized marijuana seeds for their strains because they are easier to grow than regular female marijuana seeds and are too unstable to reproduce, although some people use female plants from feminized marijuana seeds to get cuttings, it is advisable that they use female from Regular marijuana seeds. It is recommendable to start growing with Feminized marijuana seeds, this will mean that the final plant won’t have any undesirable surprises like marijuana seeds reducing potency since there are only female marijuana plants.

Male vs. Female Cannabis- Why it’s important to know before you grow

Just like humans, cannabis and hemp plants are considered dioecious, meaning they have either male or female reproductive organs. Depending on the goal of the cultivator, it’s crucial to know the gender of their plants prior to harvest.

Both male and female cannabis plants have their benefits; growing both can result in cross-pollination and thus seeds, resulting in new genetics or seeds for the next crop. However, if your goal is to produce quality buds rich in cannabinoids, it’s crucial to isolate the males from the females to avoid pollination and seed production. Cannabis pollen is extremely potent; studies have shown that pollen can drift across 3 to 7.5 miles, and can reach over 30 miles if high winds are present.

Removing males will allow the female plants to grow abundant, seedless buds (called sensimilla ). When female plants are left unfertilized, they use that extra energy meant for reproduction to produce higher levels of cannabinoids like THC or CBD, depending on the strain. The resinous buds consumers purchase at dispensaries are all sensimilla.

How to Visually Determine the Sex of a Cannabis Plant

Cultivators can visually determine the gender of their plants about 4-6 weeks into the growth cycle (though this may differ for indoor grows) when the plant is transitioning from its “vegetative” stage into the “flowering” stage. At this time, the plant is no longer focusing its energy on growing bigger and taller and instead spends all its effort growing flowers for pollination and reproduction.

When a cannabis plant is beginning to enter the flowering stage, cultivators should pay careful attention to the area between the nodes of the plant, where the leaves and branches extend from the stalk. Pre-flowers will begin to form in the nodes of the plant, and characteristics of the pre-flower will vary based on gender.

Pre-flowers can initially be difficult to examine with the naked eye, but growers can use a magnifying glass to get a closer look. Female cannabis pre-flowers grow as tiny bracts which will eventually produce hair-like stigma; male plants produce small, round balls as the nodes.

In some cases, a plant may exhibit both male and female pre-flowers. Hermaphrodite cannabis plants can occur when a plant becomes excessively stressed due to things like plant damage, bad weather, disease, nutrient deficiencies, and poor genetics. Hermaphrodites can also produce anthers, often referred to as “bananas” due to their appearance. It’s important to monitor plants that have been exposed to stressors to ensure they don’t begin to develop both male and female genetics. Hermaphrodites are capable of producing pollen and can ruin an entire crop.

How to Determine Gender Before the Pre-Flower stage

Lab genetic testing can determine a plant’s gender as soon as it begins to sprout its second set of true leaves. Knowing sooner can help cultivators save money, increase canopy space, and decrease labor costs associated with transplanting, watering, monitoring, training, and removing unwanted male plants.

Just as humans have X and Y chromosomes, cannabis also has a genetics system that determines the plant’s gender. However, figuring out the gender based on the DNA of a plant prior to the flowering stage is not as simple as looking for an X and Y. Luckily, the specific genetic sequence that differs between female and male plants has long been discovered, so using quantitative polymerase chain reactions (qPCR) allows labs to determine the gender of any plants with 100% confidence.

When a sample is brought in to Infinite Chemical Analysis Labs for gender identification, qPCR analysis is used to determine if the plant is female or male. A small hole is cut out of the leaf of the plant and added to a lysis solution to destroy the plant cell walls, exposing the DNA. After isolation of the DNA, it is transferred to another plate that contains reagents to amplify and cause the sample to create a fluorescent light that our qPCR instrument then quantifies, and determines the gender of the sample based on the amount of fluorescence.

Between sufficient lighting, proper nutrients, a detailed watering schedule, and constant monitoring, identifying the sex of your plants is another tedious yet crucial task that could make all the difference come harvest season.

Gender identification testing is now available at InfiniteCAL to help cannabis and hemp cultivators take the guesswork out of their grow. If you’re interested in learning more about Gender Identification Testing, reach out to our team at [email protected] .
