How to Get More Female Plants From Regular Seeds

Statistically, cannabis produces more male plants than females. Using these techniques can increase the number of female plants grown from regular seeds. Make the most of your time, space, and precious dollars by boosting the number of females every grow.

Unless you are planning on doing some breeding of your own and you’re looking for a perfect male, female cannabis plants are what growing marijuana is all about. However, unless you purchase feminized seeds from a reputable source, females aren’t always guaranteed. In fact, statistically, regular cannabis seeds will produce 75% or more males per crop.

It is impossible to tell if seeds are female or male, and very difficult to tell if a young plant is male or female prior to the plant differentiating. Males do have some differing growth characteristics, but it is not always easy to recognize boys from girls in the vegetation phase.

There are techniques and tricks of the trade that can be used for increasing the likelihood of getting more females from regular seeds. The key words here are a “stable growing environment.” Stress tends to produce more males, and undue stress during flowering can turn plants intersex.

STABILITY IN THE ENVIRONMENT

Stability of the growing environment is essential to increase the female to male ratio. From the moment the seeds are germinated, a growing environment with as few fluctuations as possible is ideal. Stress is the enemy when trying to get females

This is true of all the essential requirements for plant growth. Maintain stable temperatures and humidity. Make sure the photoperiod begins and finishes at the same time every day. Be sure there is no light pollution interrupting plants during the night cycle. Be sure the nutrient mixes are exact every watering. Spikes up or down in nutrient mixes can cause stress, increasing the chance of males.

GIVE SEEDLINGS LESS HOURS OF LIGHT

In the rush to get buds in the jar sooner, it is always tempting to expose plants to 24hrs of light during the vegetation cycle. The plants may grow larger sooner, but this increases the risks of males developing.

Young plants exposed to an 18-6 day-night photoperiod increases the chance of females. The chance increases further when the day length is reduced to 16 hours. To maximize the possibility, reduce the day period to 14.5 hours of light.

Shorter day length does slow growth during vegetation, but the likelihood of females increases to 70–100%. With expensive primo seeds, it is better to allow an extra week of vegetation to get the best value. Some patience during vegetation is preferred to throwing half the crop away later on.

The other downside of 24hr light exposure during vegetation is poor root development and interrupted gas exchange in the rhizosphere. Root development occurs predominantly at night, and necessary oxygen exchange occurs more efficiently at this time too. Healthy roots mean healthy plants.

USE COOL, BLUE LIGHT

Light that is in the blue spectrum during vegetation promotes female development. Fluorescent lights should be white or blue spectrum for infant plants. Refrain from using the purple/red-tinted fluorescents, which are better for flowering.

Metal halide lamps are ideal for the vegetation phase of cannabis. They are blue biased in their spectrum and imitate summer light effectively, which is the natural vegetation period of cannabis. When the 12-12 switch is made to promote flowering, switch to a high pressure sodium light. These a red biased in their spectrum and imitate the red-shifted light of autumn.

INCREASE NITROGEN

Cannabis plants consume lots of nitrogen during the vegetation phase. Increasing nitrogen (N) slightly and reducing potassium (K) can increase the likelihood of females. A potassium-rich nutrient blend will boost the chances of males during the early development phase.

HIGHER HUMIDITY AND MOISTURE IN AIR AND SOIL

High and stable humidity levels from germination right on through to vegetation increases female development. Similarly, consistent and stable watering routines maintain ideal moisture in the grow medium. Stable moisture exposure in the air and medium promotes females.

Young plants: When plants are young, make sure they maintain a high humidity of at least 70–80% RH. This is easily done with a humidity dome during the infant stage. Make sure the growing medium does not dry out too much. There is a fine line between maintaining a healthy wet-dry cycle and over drying. The stress of a too-dry medium will encourage male development.

Pubescent plants: Maintain humidity at 70% RH. Use a hygrometer religiously to ensure ideal moisture content of the growing medium. Maintaining correct humidity is made easier with a humidifier/dehumidifier unit always at work in the grow space. Continue to monitor the moisture content of the grow medium. Overwatering and over drying are stress vectors that can encourage males.

Flowering: Decrease humidity slowly to 40–50% during the flowering phase. Refrain from dropping to this level in one go. Gradual humidity reduction will prevent stress. Too high humidity can cause numerous problems for cannabis flowers. By now, the sex of the plant has been established from the specialized treatment during the vegetation phase.

DON’T STRESS

Following these easy-to-maintain tips can maximize female plant development. Stress of any kind is the enemy of marijuana. It is thought that male development increases the likelihood of pollination during times of stress. A single, well-pollinated female can produce hundreds of seeds, perpetuating the species into the next season.

Indoors, the grower has complete control over the growing environment. This means that any stresses can be minimized with vigilant plant care. Well-maintained young plants increase the likelihood of female plants, which means more buds in the jar at the end of the day.

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] .

Cannabis Gender: Male Versus Female Plants

Many growers believe they cannot correctly identify the sex of their cannabis plant until the flowering stage. Good news! Cannabis “pre-flowers” will help you to identify the sex of your plant within 3-6 weeks of germination. These pre flowers can show up on male plants as early as 3-4 weeks from germination and on female plants as early as 4-6 weeks from germination. These results may not always be accurate so it is always best practice to wait until flowering to be 100% sure on the sex.

Yes! Female cannabis plants will create seeds when a male plant pollinates them.

Only female cannabis plants produce buds!

How to tell if your cannabis seeds are male or female?

Cannabis seeds are normally 50% male and 50% female. If you are wanting to grow a female plant from seed, you can order feminized seeds online. If male cannabis plants are introduced into a garden with females, this will cause pollination which will result in the female plants producing seeds. Buds with seeds produce a harsh smoke and a low quality product.

It is possible to get hermaphrodite cannabis plants. That would be a plant that developed both male and female sex organs. So the plant is capable of pollinating itself, and every plant in the grow room!

Male cannabis plants produce pollen which can fertilize female plants and cause them to produce seeds.

How to identify the gender of your cannabis plants?

Male cannabis plants will develop their pollen sacks before the females produce buds. It only takes 1-2 weeks for pollen sacks to show up on the male plant. Females show their gender around 2-4 weeks.

When looking to tell what sex a cannabis plant is, you have to look at where the branches grow off the stalk. These are called nodes. If your plant is a male, it will have round balls on the nodes. If your plant is female, it will have small flower clusters with long “hairs” poking out. These differences will be apparent around 4 weeks into plant growth, they are called pre-flowers.

Examine your plants carefully as identifying sex in the first month of grow can be very difficult.

Things to look for when determining gender:

  • Male plants are normally taller
  • The calyx (center part of flower) on female plants will be large and have white hair. On male plants it will be small with no hair.

* You may need a magnifying glass to tell the distinction at this stage!

To get the highest quality buds, growers will want to do everything they can to prevent pollination!

MALE CANNABIS PLANT

How to identify a male cannabis plant:

Male plants will mature much faster than female plants. They will grow faster and within 2 weeks should be taller than the female. They will begin their flowering stage almost a month before the female plants.

⠀⠀⠀⠀
Features of Male Plants:

  • Less flower development
  • Straight growth
  • Flowers will be close knit green clusters

FEMALE CANNABIS PLANTS

How to identify a female cannabis plant:

Male plants have what is often referred to as “false buds” but they are in fact pollen sacs!

Female plants, on the other hand, have flowers that will resemble sacs. These sacs open to have yellow or white flowers. Additionally, they will have pistils (resembles hair).

Features of Female Plants:

  • Flower development
  • Pistils

You can guarantee females by getting feminized seeds or female clones!

What about hermaphroditic cannabis plants?

Some cannabis plants can be hermaphrodites. This is when the female plant will develop both the male and female sex organs! A hermaphroditic plant can result in the plant pollinating itself and your entire grow. This most often occurs when your plant is stressed out. Monitor the temperature, humidity, and pH closely! And always look out for pests, pathogens, diseases, and other factors that may cause your plant stress.

Male and female cannabis plants must be separated unless you want to produce seeds!

What to do when you get a male cannabis plant?

Most growers find and terminate all male cannabis plants in their grow. This is understandable if you want to ensure no female plants get pollinated. However, male plants are still of value. If you want to continue to grow your male plants we recommend growing them in a separate room from the females to discourage pollination. Male cannabis plants can be used for breeding, concentrates, hemp, and more.

When a male and a female cannabis plant are bred, the male provides 50% of the genetics. This can be helpful in breeding strains that are mold resistant, have more resin, higher THC content, etc.

Most growers dispose of male plants

While male plants often contain less THC than female plants, you can still find cannabinoids in the leaves, stems, and flowers. You can extract resin from male plants to create concentrates like hash, oil, and wax. Even the pollen contains THC! Male plants produce copious amounts of pollen, which can be collected, pressed, and consumed to give you an adequate high.
