XX Female Information: Look no Further!

First of all, I'd like to state that the information found herein has been found through intensive research on the subject, and come from several different sources. As far as I have researched, it is possible to create a non-hermaphrodite plant that will create nothing but female seeds, and I will forego explaining this process.

Now, before I delve into how it's done, I should probably explain just what an XX female is. When stress is administered to the marijuana plant, it will, in an inherent attempt to keep the species alive, become a hermaphrodite. Hermaphrodites are self-pollinating plants, meaning that there is no other genetic code besides that found in the hermaphrodite that leads to its growth. However, a very small number of plants are not able to become hermaphrodites. As much as they try, they cannot expel pollen, and are only capable of producing seeds. Those that grow these seeds say that the two plants are complete sisters, cloned from seed rather than stem. It is much easier to produce these special females with indicas, though it can be done with sativas.

Now that you have a small background of these XX females, let's get into how they are created. First, make sure that your tests for the XX female is done FAR AWAY from your other plants. Some suggest in another room. I on the other hand, judging by how far pollen can travel (and there will, more than likely, be pollen) would suggest another grow site. This is not important to the process, however, I just want to make sure no other plants are harmed through this research. It is also wise to stick to only one strain, as more strains mean a much longer process. Both will require an abundant amount of seeds or plants, so it would be wise to also pollinate one of your girls so that these seeds are free.

There are two ways to go about creating the XX female. Starting at late vegetative or pre-flowering, stress the plants creatively. If it is about to flower, turn the lights on for 24 hours. If they look too healthy in vegetative, turn the lights off for a while. Keep doing this, removing any hermaphrodites you see. Eventually, one of your plants will produce seeds, but will have no male flowers. You should be able to tell if they are male flowers, as they will have the pollen balls. If you are still unfamiliar, search the threads to see what hermaphrodites look like. If your plants don't look like hermaphrodites, but have seeds, you may have created your XX female! However, make sure to document the schedule for your plants. One documentation that I know of reads like this: 12/12 for 10 days. 24 for the next day. 12/12 for 3 more days. 24 for another day. 12/12 for two weeks. This method does work, and if you are not a creative person, you can stick to this. Note that you may not find your XX female in one grow. It might take a while, but it will be worth it.

While not exactly XX females (because it takes more than one plant and not exactly EVERY one will be female) feminized seeds can be created using the below method. I would have to credit Soma and Zandor for creating his article, and I would also to like to take some time here to thank him for his wonderful articles in High Times magazine. There is no need to re-explain his method, But I will do a quote.

I have use gibberellic acid, light stress, ph stress, and fertilizer stress to force my plants to make seeds. All these methods are harsh on the plants, and some like the gibbrellic 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, other than genetics. All cannabis plants can and will make male flowers under stress. Certain strains like a higher PH, some like a lower one. Some like a lot of food, some like a lot less. There is quite a lot of variety in marijuana genetics, and you canâ??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 strains for 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 learning new and better ways of working with this sacred plant.

I named this new method â??Rodelizationâ?� 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 plant in the same conditions, I noticed that if I flowered the plants 10-14 days longer than usual, they would develop male â??bananasâ?�. 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 in case of sever conditions, the plant can make sure that 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 least take tweezers and pluck the little yellow emerging devices out. I call them â??Emergency Devicesâ?� because they emerge at times of stress.

In the Rodelization method, the male banana is very valuable. After growing your female plant 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 to two months and still remain potent.

For the second phase you need to already have a crop thatâ??s already 2 ½ weeks into flowering. Take your sealed bag 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 down all the fans in the grow room. Then take a very fine paint brush, 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 ten 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 youâ??re one of those growers that has 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 bananas can be brought into the room with the younger, un-pollinated females when 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% female 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: â??Drop seeds not bombsâ?�.

Now the question is, now that you have all of these seeds, what will you do with them? Sell them to me, of course! Just kidding. Seriously, though, many people would pay top dollar for seeds that they know will be female, as this saves a lot of time and energy. You should always check first, though, to make sure that they are female plants.

If any of the information herein is false, and can be proven thusly, please post the correct information, so we all may learn.

My female seeds are made with no male flowers. Just light stress.

Very informative info both of you thank you. Cant wait till the next issue of High Times comes out next month. Its going to be a all organic issue or so they tell me.

I'll definitely have to pick that up. Nothing better than the taste of organics.

Autogamy 1. Self-fertilization, the fertilization of a flower by its own pollen. 2. The fusion of nuclei in paris within a single cell of the female organ but not accompanied by cell fusion.

Inbreeding 1. In plants, self-fertilization (the most efficient and rapid method to produce homozygous genes to obtain a pure line). (result-karmaxul)

Inbreeding depression The reduction in vigor often observed in progeny from matings between close relatives. Inbreeding depression is due to the expression of recessive deleterious alleles and is usually severe in open-pollinated outcrossing species that occur in fairly high population densities.

Introgression The movement of genes from one population into another through hybridization followed by backcrossing. Usually refers to movement of genes from one species to another or among sub-species that have been geographically isolated then brought back together by changes in the species ranges or planting of exotic populations.

Locus 1. The position of a gene on a chromosome in a linkage group or on a chromosome map.

Meristem The undifferentiated formative or generative cells of plants which give rise to daughter cells capable of further division, the cells found in the cambium or growing points capable of further development. (not really sure if this one belongs in here but just in case)

Ortet The original plant from which a clone is started through rooted cuttings, grafting, or tissue culture, or other means of vegetative propagation. The original tree used to start a grafted clone for inclusion in a seed orchard is the ortet.

Hope this isnt annoying

Phenotypic variation Variation produced by changes in environment.

progeny The subsequent generation following a mating or crossing of parents; offspring.

Recombination frequency The frequency at which crossing over occurs between two chromosomal loci; the probability that two loci will become unlinked during meiosis. (not really sure what it means right now I am reading the dictionary of botany but it may have some thing to do with breeding)

Selfed Fertilized by its own pollen, self-pollinated.

Selfing The pollination of a stigma with pollen from the anthers of the same flower or plant.

Somatic embryogenesis Embryos are produced either from somatic cells of explants (direct embryogenesis) or by induction on callus formed by explants (indirect embryogenesis). a.k.a. asexual embryogenesis.

Stigma The tip of a pistil which is receptive to the pollen grains and upon which they germinate.
