how to make feminised cannabis seeds

Wouldn’t it be sweet if it was possible to grow all females from seed, every plant, every time?

MAKING FEMINIZED SEEDS

The easiest and relatively inexpensive way—considering how much money is potentially saved by not growing resource and time-consuming males—is to buy a colloidal silver generator, which is the no-fuss plug and play option. Or, make your own, which is quite straightforward and doesn’t require any special skill.

The only bummer, unless you grow from clones, is that cannabis is wired to produce about 50% male seeds and 50% females. It is just the nature of the beast.

When sexing begins, male pollen sacs will develop instead of female calyxes and pistils. Male plants mature much faster than females, and viable pollen can be expected within 3–4 weeks once the plant has been sexed. Some growers will spray until the plant shows sexual growth, just to be sure the method has worked. Make sure these plants are well-isolated from any flowering females. A burst pod can release millions of pollen spores, and it only takes one spore per hair to create a seed.

To further remedy this, take 100 ml of the mixed STS and add it to 400 ml of distilled water. Now, one has 500 ml of usable and plant-friendly STS. Use the mixture on the same day it is made to get maximum efficiency. When not in use, store the STS away in a cool, dark place. The mixture can last for up to 15 days, but each passing day makes the mixture less potent.

To use this method, spray the colloidal silver on the plants’ branches every three days before switching to the 12/12 light cycle. Continue spraying until the first male flowers become visible. The more one uses colloidal silver, the more pollen sacs are produced. As the male plants mature, it will produce pollen that can be collected and used on the females.

When making feminized seeds using STS, one can combine different strains, thus resulting in a feminized hybrid that one has made himself, which is very satisfying. For instance, one can combine a K Train strain with a Critical Cure strain and get a different phenotype with various structures and qualities.

Making STS

If done right, the user will end up with 50 ml of silver thiosulfate, which is too potent to use on cannabis plants. One can tone down its potency by adding the STS to 400 ml of distilled water in a bottle and shake the mixture until it is completely mixed. This now leaves one with 450 ml of STS which is still too concentrated for use on plants.

Colloidal silver is a substance that is produced by suspending microscopic particles of silver in liquid. These silver particles measure no more than 100 nanometers and cannot be seen by the naked eye. Bottled colloidal silver can be purchased online through shops like Amazon or made at home which is a relatively simple task. If one is looking to use it for only a few times, then it is best to just purchase the colloidal silver instead of making it on one’s own.

STS suppresses the production of ethylene in plants. When properly applied on cannabis plant’s bud site, the plant does not produce ethylene. Again, male flowers are formed when ethylene is absent.

The main concern with using this method is that some cannabis strains are unable to naturally grow male characteristics. The rodelization method also requires one to look for plants that have a natural tendency to show their male characteristics. Doing this will give the plant a chance of producing offspring that have male characteristics as well.

The more you use it, the more pollen sacks you will get. As the plant matures it will produce pollen that should be collected and used to pollinate other female flowers.

This is why the process of pressuring the plant to produce female seeds en-masse is called feminization.

Gibberellic acid isn’t expensive at all, you can order it online or buy an entire box for as low as $15 bucks.

Feminizing seeds with colloidal silver

Spray colloidal silver on the branches every three days prior to switching the lights to 12/12 and continue spraying it until you start seeing first male flowers.

In the wild and without any human tampering, cannabis plants produce mostly female seeds when they “perceive” that they’re approaching the end of their lifetime.

You can get bottled colloidal silver on Amazon, or you can make it yourself, which is also relatively simple.

Those plants will yield feminized seeds after being pollinated.
