Spray bud sites thoroughly, drenching them with colloidal silver every single day. Bud sites are located wherever leaves meet stems.
November 27 – Pollen sacs are opening up! Collect the pollen before they’re all open!
4.) Pollinate Another Female Plant
There are two main ways to make feminized pollen:
This sativa plant treated with STS started flowering as a female but soon developed male flowers
The sex of cannabis plants is determined in the same way as ours, through the so-called sex chromosomes or genosomes. Male plants have a couple of different sex chromosomes called “XY” or heterogametic, while female plants have two chromosomes called “XX” or homogametic. When crossing a male (XY) with a female (XX), we will obtain around half of the plants of each type in their offspring. In other words, when a breeder uses a male and a female plant, the seeds produced by them will be approximately 50% males and 50% females.
This is another way to revert the sex of the plants, but this time using a solution made of 30ppm colloidal silver (that you can easily find in many pharmacies and also online) and distilled water. The solution must be applied for a few days until the plant starts producing male flowers, something that it´s not necessary with STS, where in most cases one single application is enough.
Urban legends and lies about feminized seeds
Although this action will produce far less pollen than other techniques like STS, it will be enough to obtain a handful of seeds for the domestic growers to try to create their own feminized crosses. Also, the great advantage of this technique is that is 100% natural, and it doesn´t use any chemicals. It is an excellent alternative for anyone who just wants a few seeds and wishes to keep it simple without any formulas or laboratory products. However, bear in mind that this is the only method listed in this post that may produce some plants with hermaphroditic traits.
Colloidal silver is formed by electrically charged silver nanoparticles and has antibacterial and antifungal properties. This product was introduced in the market in 1980 for therapeutic use. However, as with STS, you should get rid of the sprayed plants once their pollen is harvested, as colloidal silver is absorbed systemically by the plant and remains in its tissues.
One of the first methods used to obtain seeds that produce female plants was stress or rodelization. There are several ways to stress the cannabis plants to make sure they develop male flowers, such as through temperature, nutrition, photoperiod, and pH. However, supporters of this technique often prefer something as simple as delaying the harvest 2-3 weeks in order to force the plants to develop a few male flowers without stressing them as much as with any of the other methods we have mentioned.
Stress or rodelization
Nothing could be further from the truth. It is true that sometimes some plants develop weird traits or mutations, although this also happens with regular seeds. Unfortunately, there seems to be not enough studies comparing the ratio of specimens with mutations of one or other type of seeds; however, given the millions of feminized seeds that have been germinated in the last 20 years, if mutations would pose a problem, the quantity of feminized seeds sold would certainly not be so high, and this would be a “public security” issue within the cannabis sector, both for the growers and the producers of the seeds.
Despite the fact that, after two decades of cannabis cultivation, many of the false myths surrounding feminized seeds have been debunked, from time to time we still hear some arguments like the ones shown below. As is often the case, many of these stories are spread by people who have never grown this type of seeds or have none or very limited experience with them. Ignorance is always a bad thing, and that’s why we want to emphasize several points in relation to feminized seeds and the myths that often go with them; myths such as the following:
You can find colloidal silver at bricks and mortar natural foods stores or through online supplement stores. If you want to make your own, there are plenty of guides online that show you how to do that.
Pluck the pollen sacks. Place them somewhere that allows them to dry. The drying process should take about a week.
Growers normally buy feminized seeds from breeders and seed banks because they can count on almost all of those seeds becoming female plants with high THC and all the other goodies cannabis has to offer.
Step 3: Harvest & Dry the Pollen Sacs
You can use a can for this, too. The sacs will release pollen when you shake them. Keep your container closed while doing this so that no pollen escapes.
The trick to rhodelization is to fool the girls into “thinking” that they’re dying. A female anticipating death wants to optimize the continuation of the species. When they think they’re doomed, they will produce female seeds almost exclusively. This is because a small number of male plants can fertilize an entire room full of girls, so very few of them are needed. Cannabis pollen outdoors travels far and wide. The girls are more essential.
Step 4: Put Your Sacs in a Bag & Shake ‘em Up
When the buds start forming, put colloidal silver in a spray bottle and drench the bud sites once per day. The buds will develop into male-like buds that have the power to pollinate. The process will take three or four weeks. Don’t stop spraying them until the pollen-filled buds start opening and the leaf that protects the pollen begins to crack.
Let these ladies grow through the vegetative stage.
