different feminizing methods

Discussion in 'Advanced Growing Techniques' started by Destroyer1, Jan 20, 2011.

  1. hello first off im posting this because i know alot of people are interested in the feminized seeds so here,s a list of the different methods of feminizing seeds i collected these from different forums around the internet and from what ive read they seem to be legit give em a try and find out for yourself enjoy from the destroyer.

    first off a simple method for useing gibberelic acid you will need a ppm meter for this.

    GIBBERELIC ACID METHOD.
    ------------------------------
    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.

    COLLODIAL SILVER METHOD.
    ---------------------------------
    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).
    Step 1... Get some 99.9% pure (or better) silver. Coins work well.
    Step 2... Get some RO or Distilled water.
    Step 3... Get a 9v battery (or any other DC power source 6-12v)
    Step 4... Hook that shit up like in the picture. After about 2 hours w/ a 9v the water will look cloudy, like in the pics.
    Step 5... Put it in a spray bottle.
    Step 6... Mist whatever branches you want turned male. Twice a day, about a week into your flowering cycle.
    Step 7... Repeat Step 6 for 2 weeks. Stop when you see the fans leaves get a greyish hue.
    Step 8... Don't talk about Fight Club.


    ASPRIN FOR MALES METHOD.
    --------------------------------
    I hear many arguments if people should buy feminized seeds or not. I recommend buying normal seeds so you have both male and female. Then when they flower, separate the males and females. DONT KILL THE MALES LIKE YOU USUALLY DO. Then feed the males with with ASPRIN. You know...Bayer or St. joseph. Feed them the aspirin just like you would feed them your nutrients. For example, i have a 3.5 gallon bubbler bucket, i feed them with new nutriets every three weeks. Same thing with the aspirin (after flowering) i feed them 1 crushed 80mg tablet every three weeks. After the aspirin treatment, the hormones in the males should change dramatically. When both male and female are ripe, you should begin the mating process. Heres a trick i picked up to easily mate (i forgot the site). Get a wet brown paper bag, and put it on the male branch. Tight the opening of the bag with a rubber band and shake the branch for 15 minutes. Quickly take it to a female branch, tighten the opening and wait for the bag to dry. after it drys, shake the branch for 30 minutes. The females should be fertilized and wait a few days for the seeds to ripen. Plant the seeds and they should come up female in the future. When i feed the asprin to the males, i play it safe and put in one tablet. You might have better luck putting more in (like 1 tablet per gallon). I only tried this once and i had good success. Can some one try this and tell me their success? I never tried giving both sexes asprin...

    ASPRIN FOR FEMALES METHOD.
    ----------------------------------

    I've been feminizing using aspirin for years.
    I add uncoated aspirin (two aspirin per gallon, for 3 consecutive waterings) to my confirmed fems, at beginning of flowering stage. After a few weeks, they will produce a few pollen sacks filled with femmed pollen. Only draw-back is by the time the pollen sacks are finally ready to open, it's time to harvest. (but is ready to be painted onto next crop of fems)
    Have never heard of 'feminizing' a male's pollen, but definatelly do not want to have that much pollen/potential pollen floating around my growspace.

    RODILIZATION METHOD FROM SOMA.
    ----------------------------
    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”. Soma

  2. Thanks for the information. I've been thinking of feminizing my strains so that I don't have to keep clones of 9 or more of them.

    I just bought the silver for the colloidial silver method. I'm intrigued by the Rodelizing method too and can't wait to get that one going too. Never heard of the Aspirin method. I'll have to try that one too, sometime. But first, and soon, I'll try the CS.
