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.

As a farmer who has been forced to move his genetics far away from where they started, I know very well the value of seeds. My friend Adam from ThSeeds in Amsterdam has a motto that I love to borrow these days: Drop seeds not bombs.

How can I get my plants to produce femenized seeds?

There are two methods that I am familiar with; Light-Poisoning, and Gibberellic Acid Treatment, both forcing female plants to produce male flowers and pollinate themselves. I have employed both methods, and both have yielded satisfactory results.

NOTE: YOU MUST START WITH FEMALE SEEDS/CLONES TO ENSURE THAT THERE WILL BE NO MALE CHROMOSOMES PRESENT.

LIGHT-POISONING METHOD: During the first three weeks of flowering, turn the lights on for an hour during the middle of the dark period. That is, 12 hrs. on, 5.5 hrs. off, 1 hr. on, 5.5 hrs. off, and repeat for the first 3 weeks, after which you may return to the normal 12/12 light cycle. This causes a plant to go "hermie" and pollinate itself, as well as any other female in the room. You must use plants originating only from female seeds or clones to ensure that no male chromosomes are present. The resulting seeds will produce NO MALE PLANTS!


GIBBERELLIC ACID TREATMENT: Select your favorite female plant and spray it from approx. two feet away (first under the leaves, then on top). This must be done 2 weeks before the plant is put into the flowering light cycle, thus the need to start with female seeds/clones. DO NOT SMOKE BUD TREATED WITH GIBBERELLIC ACID! Spray the plant again after 2 weeks have passed, and place it under 12/12 lighting. This plant will "hermie" and pollinate itself and other females present. It will not produce as much pollen as a pure male, thus less seeds. However, these seeds will be 100% female.


CONCLUSION:
Now, femenized seeds have also been known to produce hermaphrodites. This is just an evolutionary safety precaution to ensure the survival of the species in the event of environmental catastrophe. All seeds have the potential to hermie. Variables such as pH levels, lighting scenarios, fertilizer problems, etc. will also be factors in the outcome of the plant's sex. Just keep 'em healthy, and give them your tender, loving care, and you should be fine.

I read you can let the flower finish its cycle and due to stress of not having a male present to pollinate, she will grow a few pollen sacks of her own (hermaphrodite). Thus giving you feminized seed.

I will tell you that 'pal' because by cutting and pasting information that is incorrect you're equally culpable of spreading incorrect information as the original author.



Firstly, I don't give a shit about who the original author is and he may well possess more knowledge than I do about this, neither do I profess to be an expert on 'breeding' but I know enough to know that the process he's describing will NOT give you 100% feminised seeds, so in that respect his knowledge doesn't appear to be much greater than the majority of people contributing to this thread - yourself included.

The process for producing 100% feminised seeds starts with the selection of a 100% female plant with recessive or absent hermaphrodite genes that cannot be turned into a hermaphrodite through environmental stress. Once that plant has been found from thousands of potentials the process starts with hormone treatment to produce some male flowers and the process continues as described by the original author. Note the turning of the plant into a hermaphrodite is a chemical one - not an environmentally induced one as hermaphrodites produced from environmental stress contain the hermaphrodite gene and will pass that down to all it's offspring.

It's the search and testing for this 100% true female plant that takes so long, that makes feminised seeds so expensive and one of the reasons not all strains are available in feminised versions.

If it was as easy as your 'author' described to produce 100% feminised seeds, why aren't they available in all varieties?

I'll let the readers of this thread decide who has the 'greater knowledge' in this.
First off, you are a moron. If a plant is having to be manipulated to bring out a trait then that trait is a recessive trait. A true hermaphrodite will show its traits under normal/optimum conditions and not have to be manipulated through chemical or environmental means. The Rodelization (spelling not sure) method as described earlier is the same method that has been used by many breeders I know for the past 20+ years. Sorry you can't even understand what you yourself wrote well enough to see the light.
Listen everyone please... if you don't have a clue what you are really talking about... Please, please, don't try to answer questions. You only make yourself look like a moron in the end.
