do feminized cannabis plants produce seeds

In many ways, feminized seeds can be a good option for new growers, as they eliminate some guesswork and reduce the pressure to quickly and accurately identify and eradicate unwanted male plants. However, there are no guarantees and new growers should still do their homework and know how to spot a male cannabis plant.

Growing cannabis is all about your goals and preferences. There is no inherent reason why regular female marijuana seeds would be considered better than feminized seeds. With that said, feminized seeds:

Feminized cannabis seeds are very mainstream. You can buy feminized cannabis seeds online from seed banks around the world. And if you live in a place where home cultivation is legal, you should be able to purchase feminized seeds at most dispensaries. You can also feminize seeds on your own, but to get the best feminized seeds, buy them from a reputable breeder or seed bank.

Do feminized seeds produce seeds?

Autoflowering seeds have been bred to move into the flowering phase without needing changes in light to activate the production of flowers. Whether cannabis seeds are seeds doesn’t have anything to do with when plants enter the flowering phase. Feminized cannabis seeds have been bred to grow only female plants.

While feminized seeds generally grow only female plants, there is no 100% guarantee whether you buy feminized seeds or create them yourself. Every once in a while, a feminized seed will still grow up to become a male plant. For this reason, it’s a good idea to keep a close eye on your plants as they mature. If you ever see pollen sacs starting to form, remove the plant before it accidentally pollinates and ruins your female plants.

Each of these areas may generate more questions. If you grow indoors will you use natural or artificial light? If you go hydroponic, will you also use a grow medium like rockwool or hydroton? While you could just buy a clone, plop it in some soil, and hope, it’s best to think like a beginner and do some thorough research before taking the marijuana-growing plunge.

Beyond the fact that male cannabis plants produce pollen sacs instead of flowers, having males plants around female plants can ruin an entire harvest. That’s because male plants pollinate the buds of young female plants. When that happens, the flowers will be full of seeds, lowering their quality and value.

At Greenpoint Seeds, we offer a wide variety of premium feminized and regular seeds. Some of our most popular feminized varieties include top-tier hybrids such as Purple Cake, Gorilla Punch, and Periwinkle Pie.

By “selfing” a specific female phenotype, breeders can create stable inbred lines in just a few generations. Selfing consists of using a female plant to pollinate itself or to pollinate a clone of itself. The resulting offspring will closely resemble the mother plant. Selfing is also an effective way for breeders to preserve clone-only or feminized strains.

Regular seeds usually produce photoperiod plants, although some autoflowering varieties are also available. Photoperiod plants begin flowering in response to changes in the light cycle. Indoor growers typically switch from 18 to 24 hours of light during the vegetative growth period to only 12 hours of light (and 12 hours of total darkness) during the flowering period. The reduction in light triggers the blooming of these photoperiod plants by signaling the changing of the seasons. Photoperiod plants that grow outdoors begin flowering in late summer, when the days start to become shorter. However, seasonal changes in light do not limit indoor growers.

Who Should Buy Feminized Seeds?

Importantly, regular seeds are beneficial for breeding purposes. Breeders can create their own seeds by using male plants to pollinate females. Hundreds of strains are available in regular seed form, including Indica, Sativa, and Ruderalis varieties. Growers can find regular seeds that are high in THC, high in CBD or a healthy mixture of both of these cannabinoids.

It is important to point out that plants sprayed with STS, GA3, or colloidal silver should not be smoked or consumed in any manner. Growers should only use these plants for seed production because the chemical solutions can be hazardous to human health. However, plants grown from feminized seeds are safe to consume as long as these solutions have not touched them.

Growers and breeders who are unfamiliar with feminized seeds may wonder if these all-female seeds are useful for breeding. One common question is whether or not plants grown from feminized seeds will produce offspring that are also feminized. This article describes what feminized seeds are, how breeders develop them, and whether or not they can produce feminized seeds.

Fortunately, feminization techniques improved throughout the early 2000s. As such, breeders were able to create stable and reliable seeds that were 99.9 percent female. The cost of feminized seed dropped as more efficient feminization techniques developed. Today, feminized seeds are widely popular among growers and breeders.

There are a number of solutions that can be sprayed on female plants to create male pollen sacs: benzothiadiazole, gibberellic acid, silver thiosulphate, silver nitrate, and colloidal silver.

Plants can be induced to grow male sex organs as late as four weeks into flowering. Though spraying one week prior to the light changeover is recommended for clones. If a plant grown from seed is being used, wait until the plant has sexed before spraying so you can be sure it is female.


Feminized seeds are super efficient for indoor and outdoor gardeners. Area, time, and resources aren’t being given to plants that will be thrown away two weeks after the 12-12 flip. Similarly, outdoors where a large plant can consume a lot of time and resources in upkeep prior to the autumn show of flowers, feminized plants are also a good way to reduce guerrilla crop pollinating. There’s nothing worse than bush-bashing out to a well-hidden crop only to find a rogue male or two have impregnated every female plant.

Spray the plants to be feminized with colloidal silver every day, and three times a day if you can manage. Soak them well. Do this for two weeks, then leave the plants to grow as normal. Some growers report getting results after spraying for only 5–10 days.

Plants bred using feminization are homozygous. This can have two effects that can’t be assessed until the seeds are grown. Homozygosity will increase the dominant or recessive traits of the parent in the progeny, so features you don’t want and do want can be amplified. Genetics is a weird, weird thing.
