make fiminized seeds on cannabis

This is something they do naturally as a way of perpetuating the species. When a female guesses she’s going to die and hasn’t been pollinated, she spontaneously generates fertile male flowers to self-pollinate and continue with the lineage.

It is another stress process, in this case due to over-ripe, i.e. not harvesting in time or lengthening the flowering cycle of a female cannabis plant to produce male flowers. This method is not very good because of the small amount of pollen that is created, it is not worth it if you want to make many feminized seeds.

When we choose the varieties we want to cross we have to look at the desirable qualities, such as taste, production, effect, speed, and so on. But it must be clear that these features are only useful if they are transmitted to the progeny, a good phenotype is only a good phenotype if its qualities are not transferred to its descendants. On the other hand, if it transmits those qualities, it can also be considered a good breeding tool.

⛳ Making feminized seeds with colloidal silver

The technique for producing feminized marijuana seeds with colloidal silver is based on the same theory as the STS one. Both use silver to inhibit the production of ethylene in a female plant, and that this specimen blooms as a male and releases pollen.

If you have already accomplished this step and your only concern is to know how to extract feminized seeds from a cannabis plant, I am going to explain it to you briefly.✍

Yes, there are, although not as effective and reliable as with STS, so we do not recommend them. But if you want to know other ways to make 100% feminine seeds of your favorite weed I’ll tell you. First of all you have to understand that all techniques are based on stressing a female plant to revert its sex to male, so it can produce flowers with which it can pollinate another female.

The most common technique used to cause stress to female plants was known as “Light Poisoningor light stress. It’s easy, you just have to use irregular photoperiods, or often interrupt the night cycle of female cannabis plants during flowering.

Feminized cannabis seeds quality control

There are several ways to secure that a female plant produces pollen, and almost all of them require some type of chemical that is often sprayed on the plant. Once sprinkled with the chosen product and under a flowering photoperiod, the plant will flower normally, but as a male instead of female, producing ‘feminized’ pollen (which only contains chromosomes XX) that can be used to pollinate other females in order to produce seeds. These are some of the most commonly used techniques:

Female crosses: feminised cannabis seeds are born

It is important to mention that you must not consume any part of the plants sprayed with this type of product, although that would be weird, as the plants have “become” males and won´t produce any buds. Nevertheless, you shouldn’t use the reverted plants to make resin extracts; the best thing is to discard them after harvesting the pollen. Both components, sodium thiosulphate and silver nitrate, are also used for photo-development.

These advantages were of great interest for the growers, and soon feminised seeds accounted for a large portion of the seeds available in the market. In addition, being able to use only female plants (generally known and selected clones) to produce seeds had another great advantage for seed producers and breeders of new varieties: they no longer need to keep males in their gene pools! And not only that. from that moment on, any female plant they could get their hands on could be used as a male to pollinate other plants, thus exponentially increasing the possibilities of creating new crosses.

Let’s see now the most popular ways to reverse the sex of a female plant in order to produce feminized seeds.
