Making Feminized Cannabis Seeds is Easy!
There are three main methods to create your own feminized cannabis seeds
Method # 1 - Using Rodelization
Source High Times
Creating feminized cannabis seeds is an art. Just like art, there are a few different methods of application. I have written about some of my different methods of making seeds in previous HIGH TIMES articles. I have used gibberellic acid, pH stress, light stress, and fertilizer stress to force my female plants to make seeds. All of these methods are harsh on the plants, and some, like the gibberellic acid, are not organic. In my search for cleaner, more earth-friendly ways of working with the cannabis plant, I have found a new way to make feminized seeds.
Feminized seeds occur as a result of stress, rather than genetics. All cannabis plants can and will make male flowers under stress. Certain strains like a higher pH, some a lower one. Some like a lot of food, some like much less. There is quite a lot of variety in marijuana genetics, and you can’t treat every plant the same way.
It takes many harvests before you really get to know a particular strain. Just like getting to know human friends, it takes time. I have grown the same strains for close to a decade, and am truly getting to know every nuance the different plants exhibit. I can recognize them from a distance. I must say that I get a lot of help from my friends, both in making seeds and in learning new and better ways of working with this sacred plant.
I named this new method "Rodelization," after a
friend who helped me realize and make use of this way of creating
female seeds. After growing crop after crop of the same plants in the
same conditions, I noticed that if I flowered the plants 10-14 days
longer than usual, they would develop male "bananas." A male banana is a
very slight male flower on a female marijuana plant that is formed
because of stress. Usually they do not let out any pollen early enough
to make seeds, but they sometimes do. They are a built-in safety factor
so that in case of severe conditions, the plant can make sure the
species is furthered.
To me, a male banana is quite a beautiful thing. It has the potential of making all female seeds. Many growers out there have male-banana phobia. They see one and have heart palpitations, they want to cut down the entire crop, or at the very least take tweezers and pluck the little yellow emergency devices out. I call them "emergency devices" because they emerge at times of stress.
In the Rodelization method, the male banana is very valuable. After growing your female plants 10-14 days longer than usual, hang them up to dry, then carefully take them off the drying lines and inspect for bananas. Each and every banana should be removed, and placed in a small bag labeled very accurately. These sealed bags can be placed in the fridge for one or two months and still remain potent.
For the next phase, you need to have a separate crop that’s already 2 1/2 weeks into flowering. Take your sealed bags of pollen out of the fridge, and proceed to impregnate your new crop of females. To do this, you must first match the female plant and the pollen from the same strain in the previous crop. Shut all the fans in the growroom down. Then take a very fine paintbrush, dip it in the bag of pollen, and paint it on the female flower. Do this to each different strain you have growing together. I have done it with up to 10 different kinds in the same room with great success.
I use the lower flowers to make seeds, leaving the top colas seedless for smoking. This method takes time (two crops), but is completely organic, and lets you have great-quality smoke at the same time you make your female seeds. If you’re one of those growers who’s never grown seeds for fear of not having something good to smoke, you will love this method.
You can also use this pollen to make new female crosses by cross-pollinating. The older females with the male bananas can be brought into the room with the younger, unpollinated females after they are three weeks into flowering. Turn all of the circulation fans on high, and the little bits of pollen will proceed to make it around the room. Do this for several days. Six to seven weeks later, you will have ripe 100% feminized seeds; not nearly as many as a male plant would make, but enough to start over somewhere else with the same genetics.

Method # 2 - Breed 2 Female Plants
Ever wondered how those marijuana seed banks make feminized seeds?
When you "feminize" a seed, what that means is you're ensuring that
the resulting seed will produce a female plant. Most growers only want
to grow female cannabis plants, since the females plants are the only
ones which grow buds/flowers.
It's actually pretty easy to feminize your own seeds, and you can easily make your own feminized marijuana seeds at home using the following technique.
"Feminized" seeds means all-female seeds, or marijuana seeds where 99.9% of the resulting plants will end up being female and grow the prized marijuana buds. When you have all-female plants, you won't have to throw any plants away because they end up being boys (male cannabis plants don't produce buds, only pollen).
The main idea is you get two female cannabis plants to make seeds with each other. With two female parents, all the resulting seeds end up being female, too.
The secret is a special substance known as "colloidal silver" which simply means water that has silver particles suspended in it. You can make colloidal silver at home (instructions below), with a colloidal silver generator, or you can purchase colloidal silver at health stores and online (some people drink it).
For some reason, when a female marijuana plant is exposed to colloidal silver during the early flowering stages, all the exposed parts which would normally grow THC-laden buds instead will grow male "balls" or pollen sacs. It "masculizes" the treated part of the plant.
Science: The concentration of silver ions in the water actually act as an ethylene inhibitor / antagonist on the plant, which forces the plant to create male pollen sacs instead of female buds.
The pollen produced from these special balls can be used to pollinate a female plant. Except since both pollen and bud come from female plants, you have two female cannabis parents and end up creating feminized cannabis seeds.Where do I get colloidal silver? Instructions and information below.
Method # 3 - The colloidal silver spray method
For whatever reason, when colloidal silver solution is sprayed regularly on a female cannabis plants during the early flowering stage, she will grow male "balls" (which are full of female pollen) instead of growing buds.
This allows the grower to collect pollen from a female cannabis plant. You can use this all-female pollen to pollinate another female plant. With two female plants as parents, ALL the seeds will end up being female.
That is why colloidal silver allows can be used create female x female cannabis crosses and produce your own feminized seeds.
Rodelization takes advantage of the fact that a female plant will try to pollinate herself as a last resort when she doesn't get pollinated and is nearing the end of her lifecycle. That is why sometimes older or stressed female plants grow a few male "balls" as a last-ditch attempt to self-pollinate. When successful, she will grow a few seeds.
These self-pollinated seeds will have gotten both sets of genes from the same female plant, so both parents will be female, and all resulting seeds with be female.
