Feminization of seeds
How to FEM cannabis seeds & using Silver Thiosulfate to create HERMI.
Anyone ever use this Soma tech to feminize 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”.

thank you soo much for posting this for us!

bap treated plants start to show sex sooner than control.
bap treated plants have little stem elongation vs control
bap treated seedlings resulted in all female or Bisexual plants.

so have a male? treat with bap. now its at the very least a wonderfully easy self fertilizing plant. very much like ga3 or CAg but opposite...

i made a 1000ppm bap solution tonight. will be testring it on one santa from flash. its germinating now, waiting for visibly healthy growth before treatment.

anyone else going to get in on this experment?

Only one problem here... "selfing" to the same plant tends to produce hermies offspring... so be mindful on the next round.
 
@Rodelization: In other words you select the females for hermaphrodization ... i know, you force them to give you bananas, but in the end you select for plants, which are responsive for stress.

to my eyes one should cut away from the thinking of "organic" and "non-organic" ... Think of plants grown from a callus. There is totally nothing "organic" about plant tissue culturing, but in the end offsprings generated from a plant grown from a callus cannot be distingushed from a plant grown in the wilderness. it's almost 100% genetics and only absolutely minor influence is driven by epigenetics.


the best way to my eyes to get herm free fem seeds is the following:

1.) Put each and every stress factor that is known to cause hermaphrodization on the your females
2.) Select the one that is the least responsive to this stress, i.e. stays pure female flowering
3.) Brute force a clone of this female with silver into ethylene deficency and cause male flowering
4.) use this pollen to fertilize the 2nd best female, i.e. not a clone of the female you silver treated, in order to avoid inbreed depression

Inbreed depression from selfing might raise the stress sensitivity, thus might facilitate herms.

There is nothing wrong with the silver method, it's just blocking the ethylene receptor thus causing to trigger male flower production. This method is much more brute force than any other method, which to my eyes is good ! Because it avoids any selection pressure towards hermi formation.

maybe i should have read this all, but i didnt, so im gonna go ahead and ask (sorry if i looked over the answer, if i did), i am going to order some colloidal silver momentarily... my question is this, what ppm do i get? i see cs with a ppm of 10 all the way up to 15,000... any answer will be suffecient i reckon... thanks guys...
 
Minimum of 30ppm. Some people say it's safe to smoke the CS sprayed branches but IDK, I wouldn't.
