How to make feminized seeds?

[bobmerlay]

I've searched through the archives for "feminized seeds" and i could not find any tutorial. Is there any feminized seed equipment/chemicals needed with a tutorial when to spray the plants to get it to turn hermi and produce pollen sacks... type of thread?
id like to make beans over the summer but feminized ones so i dont have to go back all the time during budding stages to periodically remove all males
it would save alot of effort to grow purely feminized

Read about using Gibberellin

Read about using Gibberellin

I have read that this material is useful in feminizing seeds. Google it. I did and found it mentioned quite a bit. It is powerful stuff but all natural. Gibberellin is produced in all green plants along with other auxins in the growing tip of the shoot of the plant. It has many other uses as well. I used to use it to push plant growth faster and to make fruit bigger. It is all applied in "parts per million" or ppm. A little bit goes a long way so 1 bottle would last you years. I have some on hand. If you can't find any post here.

But in this crop, I have read it has a useful function in making fem seeds.

Just a quick search on google using this auxin and feminized mariuana seeds I found;

But do not believe all in this guys post (about the product not being organic because it is and it is registered for use across the country by Certified Organic Farmers).


See link below to know what to look for if you give it a try.

Making Feminised Seed
To make feminized seed you must induce male flowers in a female plant. There is all sorts of information on the internet about doing this with light stress (light interruptions during flowering) and other forms of stress. The best of the stress techniques is to simply keep the plant in the flowering stage well past ripeness and it will produce a flower.
Stress techniques will work but whatever genetic weakness caused the plants to produce a male flower under stress will be carried on to the seeds. This means the resulting seeds have a known tendency to produce hermaphrodites. Fortunately, environmental stress is not the only way to produce male flowers in a female plant.
The ideal way to produce feminized seed through hormonal alteration of the plant. By adding or inhibiting plant hormones you can cause the plant to produce male flowers. Because you did not select a plant that produces male flowers under stress there is no genetic predisposition to hermaphroditism in the seed vs plants bred between a male and female parent. There are actually a few ways to do this, the easiest I will list here.
[edit]Colloidal Silver (CS)
This is the least expensive and most privacy concious way to produce fem seed. CS has gotten a bad name because there is so much bad information spread around about its production and concentrations. It doesn't help that there are those who believe in drinking low concentration colloidal silver for good health and there is information mixed in about how to produce that low concentration food grade product. Follow the information here and you will consistently produce effective CS and know how to apply it to get consistent results.
Simply construct a generator using a 9-12v power supply (DC output, if it says AC then its no good) that can deliver at least 250ma (most wall wart type power supplies work, batteries are not recommended since their output varies over time). The supply will have a positive and negative lead, attach silver to each lead (contrary to internet rumors, you aren't drinking this is cheap 925 silver is more than pure enough) you can expose the leads by cliping off the round plug at the end and splitting the wires, one will be positive and the other negative just like any old battery. Submerge both leads about 2-3 inchs apart in a glass of distilled water (roughly 8oz). Let this run for 8-24hrs (until the liquid reads 12-15ppm) and when you return the liquid will be a purple or silver hue and there may be some precipitate on the bottom.
This liquid is called colloidal silver. It is nothing more or less than fine particles of silver suspended in water so it is a completely natural solution and is safe to handle without any special precautions. The silver inhibits female flowering hormones in cannabis and so the result is that male flowering hormone dominates and male flowers are produced.
To use the silver, spray on a plant or branch every three days prior to switching the lights to 12/12 and continue spraying until you see the first male flowers. Repeated applications after the first flowers appear may result in more male flowers and therefore more pollen. As the plant matures it will produce pollen that can be collected and used to pollinate any female flower (including flowers on the same plant).
[edit]Silver Thiosulfate (STS)
Only mentioned for completeness. Silver Thiosulfate is more difficult to acquire and works on the same principle as CS. Its application is similar to CS and achieves the same results.
[edit]Gibberellic Acid (GA3)
This is probably the most popular way to produce feminized seed. GA3 can be purchased readily in powdered form, a quick search reveals numerous sources on ebay for as little as $15. Simply add to water to reach 100ppm concentration and spray the plant daily for 10 days during flowering and male flowers will be produced.

I had a look at that post greenlove, it was excellent, exactly what was needed, theres also another one I found which elaborates a bit more, but looks almost as if some of the post in that link was copy/pasted to the other one. grapeman, thanks for the info bud... thing is though its much easier to buy silver nitrate and sodium thiosulfate for £25 and thats enough to make 1000 litres of male inducing spray
very helpful gents cheers

 

[Mr. Stinky]

does anyone else find it interesting that when the subject comes up, dozens of people post up how to do it, but none of them have ever tried it themselves? not knockin you guys, just pointing that out. these fem seed threads can go on for pages without a single post from someone who sucessfully uses the process. its all just regurgitated information that was read elsewhere on the web. i appreciate the desire to help out, but at the same time, im going thru the agonizing process of learning to use GA effectively despite all the terrible information that gets posted thousands of times over on this and other forums. i can tell you, i wouldve been better off not reading any of these threads, and just trying to learn on my own. if you follow most of these directions for colloidal silver, sts, or ga, you will kill far more plants than you make. i havent used sts yet, so i cant comment on its effectiveness as posted, but i would bet its not accurate, just like all the well intentioned post on GA and CS are far from accurate.

you wanna make fems? heres a step by step
first, do a fully seeded grow of your current stock. use as many good plants as possible. only cull runts.
start your fem seed grow, and keep plants alive into flower...
cull the males
let the girls get a couple weeks into flower
mess with the light schedule by turning on the lights for an hour half way thru dark
do this every day for a week
when u see nanners, drop back to doing it once a week or maybe twice
let them pollinate them selves as well as the rest in the room
a fan will help
let the seeds mature

thats your best bet for the guy who just needs to make a bunch of feminized seeds for personal use. the seeds will be great for growing, and if you use a male to pollinate the resulting girls, you will be right back in the game to make more fems the next go-round.

no, you wont be breeding a batch of "hermies". hermies are plants that intersex regardless of conditions. you are actively stressing the plants to produce pollen for you. a very different situation. the progeny will not be hermies any more than their parents, under the same conditions, which is quite handy, since you will be needing to take advantage of that trait again when you make fems again

the only downside to this, is you cant do any selective breeding. but if you are smart, u can select your future generations for breeding by using only the seeds from the best finished plants. the ones that smoke the best, only save the seeds from them,and pollinate those plants with a strong group of males of the same strain. this kind of constant stirring of the genepool is what makes great lines.

Just for your info. Using Pro Gibb Plus has benefits,

http://www.valent.com/Data/Labels/2006-PG2X-0001 - ProGibb 2X - 04-5005r4.pdf

it’s so safe you can eat the stuff and registered and used on organic crops worldwide. You can acquire it on eBay for less or same as the other products mentioned.

The Pro Gibb Plus comes in a 160 gram bottle in powdered form.

To make a one (1) gallon solution of 100 ppm concentration (the strength required to do what you want to do) is as follows;

1 gallon H2O
2 grams of Pro Gibb Plus powder.

Resulting concentration is exactly 101.5ppm

That give you 80 mixes of 1 gallon spray. Can’t get any more economical than this.

Or if you make ½ gallon mixes and use 1 gram you would get 160 spray solutions. Even better.

i have made my own ionized silver and was able to force females to make pollen with the ionized silver it does work but the amount of pollen that is had is small so it has to carefully be collected for use. so far i have crossed tahoe og to a deep chunk/strawberry cough clone. i have also made fems using the method of allowing plants to go far past harvest date both ways work on most strains if done properly i know for certain it works well on pre 98 bubba kush. all the fems i have made and grown out have been herm free.

How to produce feminized marijuana seeds by SOMA

How to produce feminized marijuana seeds by SOMA

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.




i hope this helps

gibberellic acid is organic. It is used in organic farming and still retains the "organic" classification. But who cares anyway? It is well established that organic farming of anything is pure nonsense akin to a religion and lacking any science.

 

[Linux]

Everybody please DON'T listen to "stonecafe" obviously hes trying to fear you guys from quickly producing feminized seeds. Probably because he has his own lil seed industry or he doesn't know how to think/research before trying to educate people. But he's right about with the Rodelization part, but that takes forever and more hassle. Gibberellic Acid IS SAFE! Which can be collected in ORGANIC/NATURAL forms, EDUCATE YOURSELF!!!

P.S - I know this is an old thread, but im just trying to let the truth/right knowledge be in history.

You take them to a special doctor in thailand lol

i WOULD Not advise using GA3 , will alter the dna of the plant
you much better off with CS

my buddy has excellent results using a minimag light on certain branches to stress growth of male flowers ...

 

[GP73LPC]

Colloidal Silver is the latest method...

Is it a fact that GA3 alters DNA of the plant or is that just a speculation?

Has anyone actually seen this happened to a cannabis plant? If so can you please provide a link or proof so that i can educate myself in this subject further more.

Thanks.

THIS NOW MALE PLANT USED TO BE...

A BEAUTIFUL FEMALE

How so?.....COLLOIDAL SILVER

 

[BlueGrassToker]

Gibberellic Acid is a natural hormone that cannabis already possesses. Applying it to cannabis, be it the natural hormone or synthesized...it will not alter the DNA of the plant. The DNA strand is what allows the plant to respond to hormonal treatments. The strand itself is not manipulated. -It is what it is what it is.

Hey BlueGrassToker, that's what I was trying to tell the other guys but they keep saying that it will mess up the DNA/potency of the plant. Is there any such evidence of this? I use both CS and GA3 methods.

 

[DIDM]

I never will buy fem seed

feth all that BS




when you take nature and mutate it you get mutants not natural



the awesome thing about real seeds is you get males to play with and be your own godlike being


breed seed, and bring peace by doing so

 

[BlueGrassToker]

First of all...we really shouldn't be huffing on a plant that was chemically treated for ANYTHING! It shouldn't matter what happens to the pollen donor plant if we aren't going to smoke it...which we shouldn't if we have treated it, be it with GA3, CS, or STS.
All we want out of the donor plant is pollen. To assume that the DNA of the pollen was somehow mutated is ridiculous. What you need to do is have your buddy provide some evidence of this mutation.

DIDM, having an opinion such as yours is fine...but not based on anything even close to factual. Nothing about feminized seeds has anything to do with mutation. Quite the opposite actually. The hermaphrodite gene is one of the natural things that makes cannabis the magic plant that it is. All feminizing is, is manipulating a hormonal response that the plant can do on it's own to begin with.
Your stance sure gets shared by quite a few...but each and every one of them is misguided.
