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.

does the plant need to be pollinated or does this stress the plant and cause it to seed

another way i think this is the best. Got this from somewhere else but totally forgot who wrote it. Enjoy.

Quote:
Creating feminized seeds is an 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 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 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 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 “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 plant 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 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 “Emergency Devices” 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 that’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 you’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: “Drop seeds not bombs”.
Haven't tried it yet but it seems logical.

Dontknow, read that wonderfully informational post by the enchanting Mogie again; just look a little more carefully. If you're talking about forced feminization through light stress, it will take care of itself. There is no need to manually pollenate the buds. If you want to ensure a ton of seeds, this can be done, but for ease, I'd suggest just letting the plant do it. The light poisioning induces a hermaphroditic reaction in the plant. All this means is that the plant produces pollen sacks, which, because the plant is already a determined female, will contain no male chromosomes. It pollenates itself. So yes, pollenation is necessary, but it's not necessary for YOU to pollenate the plant. The method tricks the plant into "thinking" the climate is topsy turvy, and thus it takes steps to ensure that the species survives. Cannabis is really one of the most amazing plants found in nature.

Mogie, correct me if im wrong but.
Isnt it a fact that people stated that, if you force your plants to become hermie and produce female seeds that yes they will be female when planted but will have similar traits as the mother so it will become hermie also , and its kids and its kids. Ive read this alot on here.

First off Yes you are 100% Correct. But this doesn't mean that it will turn hermie. It picks up the trait that if light poisoned again it will turn hermie faster then the parent. So if you can keep it at optimal condition then it will stay femenize. Plus the light poisoning thing is really harsh, that means your doing your whole crop. I rather do the Rodelization method, then you can pollinate what you want, who the hell wants a crop full of seeds.

now i am about to buy 3 packs of seeds to hopefully last me a long time and im gonna pollinate them to make more seeds. so in my best interest would it be better to get feminized seeds and do the light poisoning then to get regular and let a male pollinate. im thinking of getting white widow, northern lights and maybe great white shark or big bang by greenhouse

You can't, so forget it and don't waste your time. All you'll manage to do is produce more hermaphrodites.

The first step in producing feminised seeds is to find a 100% stable female plant that doesn't have any hermaphroditic traits, found that plant yet?

Ever wondered why feminised seeds are so expensive? So much breeding involved, you think you can do that with your limited knowledge?
