Creating Feminized Seeds - Has Anyone Tried Rodelization?

Just wondering if this actually works or if anyone has tried it? I am posting the full article below and the link from where I found it.

How to produce feminized marijuana seeds

Creating feminized marijuana seeds is an art, there are a few different methods of application. I have written about some of my different methods of making cannabis seeds in previous HIGH TIMES articles. I have use gibberellic acid, light stress, ph stress, and fertilizer stress to force my plants to make marijuana 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 cannabis 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 marijuana 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 cannabis 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 marijuana 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 pot 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 weed 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 cannabis seeds. If you’re one of those growers that has never grown marijuana 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”.

I am doing this right now, but Im not sure what to look for. Does anyone have a pic of what to look for? What does the bananna look like on a female plant?

I stressed a plant to hermie once and every seed i got from it has been female....i saved some pollen...still have some of it....i hear cuz it only has y cromosones or sumthin.....too bad you aint in east michigan id hook you up.

what do the bananas look like though? I flowered 3 weeks over and don't know what to look for.

hate to say it , if you flowered 3 weeks over and still don't see any bananas then you proibly just waisted a crop

I think i need to see a pic, I always grow from clones. I have never seen a male pollen sac, let alone between hairs... sorry

I hermied mine by light stress......not sure about the banannas....i mean there were sum bananna looking things but mostly daisy looking male flowers......if u constantly change your light schedule like when u dont use a timer then your plant has good chance of hermying...someone told me that all the seeds would be hermie but ive grown 2 plants with the seeds so far and 2 for 2 female.....

I did a Google image search and turned up noda besides the male sacs. Has there been anything like a sac or an elongated sac? They might be in the nodes covered by bud. It doesn't sound like this happens every time.

Just another thought: once you harvested all but the one, did you try lowering the light time to 11/13, maybe pull the light up another six inches from the plant, and lower the room temp if possible. Seems like those things would help the odds and make the plant think it is really late Fall and it needs to reproduce.

I just came across this on Wiki - thought I would add it here.

Feminized seeds

It is possible to use a combination of cloning and "shocking" plants to get them to produce feminized seeds.[7] A clone will retain the same sex throughout its life, so if a female plant is cloned, its clones will also be female, precluding reproduction.

While environmental stresses have been used to create pollen bearing male flowers on female plants- known as 'hermaphroditing' or 'hermying', this method is not preferred when creating feminized seeds; due to those plants most likely to revert to seed making being the ones which hermie soonest; hence passing on the genetic trait of instability of gender - desirable in the wild but not in cultivation.

Spraying selected leaves, branches and in cases where large amount of seed desired whole plants with colloidal silver solution has become a preferred method since the colloidal silver suppresses ethylene production in bud sites, stimulating male characteristics. Gibberellic acid has been used frequently; but is harder to find than colloidal silver, which involves nothing more than a small wall d.c. power supply and two pieces of solid silver jeweler's wire, or 99.999% silver coin. A method used by organic growers and promulgated by the famous Cannabis breeder Soma, is called 'Rodelization', or letting unpollenated female plants live several weeks longer than the normal harvest time. In such plants a hermaphroditic trait will self express in effort to continue the genetic line; the fact this method utilizes auto hermaphroditic traits which could contribute to instability in a plant's genetics is offset by grower observations that the tendency to auto-switch sex is not great in plants grown from seeds made this way, and the fact that it occurs naturally without effort on the part of the cultivator.
