Feminized Marijuana Seeds

The cannabis buds and products that we all enjoy come from the flowers of the female cannabis plant. These flowers contain the highest levels of cannabinoids and terpenes in the cannabis plant. That’s why female plants are much more desirable when growing a marijuana crop. Male plants are significantly lower in cannabinoids and are best for breeding or hemp production. However, when cultivating a regular cannabis seed, there is a 50/50 chance that that seed will become a male plant. That means that roughly half of all regular seeds grown are unusable for most cannabis growers. Starting with feminized seeds saves valuable time, space, and money that would otherwise be wasted if the regular seeds turn out to be male.

What are Feminized Cannabis Seeds

Feminized Marijuana seeds are seeds created with the sole purpose of reproducing stable female seeds from a selected variety. The seeds are made using specific agronomic techniques that allow a healthy female plant to produce viable female pollen. That pollen is used to pollinate the flowering female cannabis plants. This practice became popular in 1998 when the Dutch Passion seed company released the first feminized marijuana seeds to the market.

Why Use Feminized Seeds?

Instead of losing half of your batch of seeds because they’ve turned out male, growing feminized seeds will increase the percentages of females in a batch to 99-100%. This means that you will generally have a higher success rate and more female phenotypes to choose from. Not to mention removing the headache of sexing the plants during the first weeks of forced flowering. Feminized seeds are also more genetically similar because they often come from two clones of the same plant. One clone remains female and is to be pollinated by the other female clone that has its hormones altered in such a way as to produce viable pollen used to pollinate the first female untreated clone during the flowering stage.

How to Make Feminized Seeds

The most common and preferred method is the application of colloidal silver or gibberellic acid to the female plants before or during the first weeks of photoperiod induced flowering. These substances will force the female plant to produce male sex organs filled with viable female pollen. The pollen is collected and used to pollinate the flowering female plants.

Female cannabis plants require naturally produced ethylene to form the buds. The silver or gibberellic acid solution suppresses the ethylene and causes the plants to produce male flowers. The flowers are full of only female pollen. For example, if you have an OG Kush strain clone and force it to produce female pollen in this way, when that pollen is used to pollinate other clones of the same OG Kush, the resulting seeds will be nearly genetically identical to the OG Kush parents and have an almost 100% likelihood of being female seeds.

They can also be made by using hermaphroditic pollen from over-stressed female plants. These kinds of feminized seeds are much riskier to use because they contain the chance of turning hermaphroditic again. Plants like this can potentially ruin a crop of female plants by releasing pollen back onto them and thus creating more seeds of unstable stressed hermaphrodite plants.

How to Grow Feminized Seeds

Feminized Cannabis Seeds are even easier to grow than regular seeds. Just follow our How to Germinate Cannabis Seeds article and follow the directions as you would here for normal seeds. The only main difference from growing regular is that when it comes time to induce flowering and sex in your plants, the feminized seeds will produce all females meaning that you generally won’t find any male plants in the batch. This removes the worries of trying to identify male pollen sacs or female pistils that can be hard to see with an untrained eye.
