    ok the random male pollen sacks. first off what i've noticed is they are not complete pods. when a male flowers it develops a "pod" looks somewhat like a bellpepper(? i guess ). inside this casing are the flowers. when the pepper opens there are 6 if i remember correctly, "banans hanging on delicate threads. these bananas open to form the pretty purple white flowers. they are really pretty just to small to fully enjoy their beauty.
    anyway when random flowers appear on female buds they seem to be only 1 banana. like a single male flower grew within a female pod. there is no "bellpepper". this is my first observation.
    second i've seen this on just about most strains. some more then others. trainwreck was covered in them, purple/ northern lights had 2 or 3. i've seen this indoors and out. i think it may bee a genetic trait designed to prevent elimination of the species.
    it's not a bad thing because you can usually get just a few seeds out of an otherwise seedless crop. then pass them out ot friends.
    now the question. since this pollen is from a female plant it should carry a dominant female gene. are these seeds feminized?

    no this is what female girls usually have to catch our pollen see it catches the pollen and distributes it to the bud. and just like us humans haveing babies mean losing money. seeds reduce the potency of your plant by about 60% so if you want a strong plant out goes the male but if you wants seed id say 6 penis from every one of those sack on it is gonna get yor lady pregnant this is just natural form of reproduction. hermis are to make sure strain stays alive there evil like an ex-girlfriend.

    not hairs.

    single male pollen sacks. like 1 on a 18" cola. it's gonna seed like 5 single female pods. i'm pretty sure FIVE seed in ONE once of bud is going to have NO effect on anything.


    :confused:
    I will rephrase:

    Am I correct in understanding, feminized seeds are produced by pollenating a female plant with pollen that came from a hermorpheditic female?


    And if so can it be the same plant?



    Will my self pollenated female plant produce female only seeds?

    How To Reverse Sex Using Silver Thiosulfate Solution
    The following is a safe, inexpensive, and successful method for reversing the sex of female cannabis plants. Individual plant responses may vary based upon strain, but I can verify that this process is fully effective in stimulating profuse staminate flower production.

    This process can be used to:

    A: create new feminized seeds from solitary prize mothers that you currently have
    B: create interesting feminized-seed hybrids from different prize strains that you currently have
    C: create feminized seeds for optimum outdoor use
    D: accelerate the "interview" phase of cultivation, in searching for interesting new clone-mothers
    E: reduce total plant numbers- great for medical users with severe plant number restrictions
    F: increase variety, by helping to create stable feminized seedlines to be used as an alternative to clones

    At the bottom of this post are some specific details about the chemicals used, their safety, their cost, and where to get them.

    It is important to educate yourself about cannabis breeding theory and technique prior to using a method like this one. Here is a link to Robert Clarke's "Marijuana Botany", which is a very good reference.

    "Marijuana Botany" by Robert Connell Clarke
    (unfortunately missing the appendices)

    It is also important to use basic safety precautions when mixing and handling these chemicals, so read the safety data links provided. The risk is similar to mixing and handling chemical fertilizers, and similar handling procedures are sufficient.

    Remember: nothing will ever replace good genetics, and some of your bounty should always go back towards the professional cannabis breeders out there... the ones who have worked for many generations to come up with their true-breeding F1 masterpieces. Support professional breeders by buying their seeds. Also, order from Heaven's Stairway. Not that they need a plug from me, but they are very professional and provide very fast service worldwide.

    Preparation of STS:

    First, a stock solution is made. It consists of two parts (A and B) that are initially mixed separately, then blended together. Part A is ALWAYS mixed into part B while stirring rapidly. Use distilled water; tap water may cause precipitates to form.

    Wear gloves while mixing and using these chemicals, and mix and use in a properly ventilated area. A mask will prevent the breathing of any dust, which is caustic. STS is colorless and odorless, and poses minimal health risks if used as described here. (See material safety data sheet links below). Note that silver nitrate and STS can cause brown stains upon drying, so spray over newspaper and avoid spilling.

    Part A: .5 gram silver nitrate stirred into 500ml distilled water
    Part B: 2.5 grams sodium thiosulfate (anhydrous) stirred into 500ml distilled water

    The silver nitrate dissolves within 15 seconds. The sodium thiosulfate takes 30-45 seconds to dissolve.

    The silver nitrate solution (A) is then mixed into the sodium thiosulfate solution (B) while stirring rapidly. The resulting blend is stock silver thiosulfate solution (STS).

    This stock solution is then diluted at a ratio of 1:9 to make a working solution. For example, 100ml of stock STS is added to 900ml of distilled water. This is then sprayed on select female plants.

    Both the stock STS and the working solution should be refrigerated after use, as well as the powdered chemicals, to avoid activity loss. Excess working solution can be safely poured down the drain after use (with ample running water) with negligible environmental impact. It's pretty cheap.

    Each liter of stock STS will make ten 1-liter batches of working solution of STS. With the minimum amount of base chemicals ordered from Photographer's Formulary (see link below), this means that each 1-liter bottle of working solution STS costs less than 9 cents, and can treat 15-20 mid-sized plants. That's 200 1-liter batches of STS for $18. Note that the distilled water costs far more than the chemicals.

    Application:

    The STS working solution is sprayed on select female plants until runoff. Do the spraying over newspaper in a separate area from the flower room. You probably won't smell anything, but ventilate anyway. You now have what I call a "F>M plant"; a female plant that will produce male flowers.

    After the F>M plant dries move it into 12/12 immediately. This is usually done three to four weeks prior to the date that the target (to be pollinated) plants will be ready to pollinate. Response times may vary slightly depending upon the strain. More specific times can be determined by trial with your own individual strains. In my trials it took 26 days for the first pollen. 30-35 days seems optimum for planning purposes.

    So, assuming that a target plant needs 3-4 weeks to produce fully mature seeds, a strain that takes 8 weeks to mature should be moved into flower at about the same time as the female>male plant. A target plant that finishes flowering in 6 weeks needs to be moved into flower later (10 days or so) so that it doesn't finish before the seeds can fully mature.

    A seeded individual branch can be left to mature on a plant for a bit longer, while harvesting the other seedless buds if they finish first. Just leave enough leaves on for the plant for it to stay healthy

    Effects:

    Within days I noticed a yellowing of the leaves on the F>M plants. This effect persisted for two weeks or so; after this they became green again, except for a few of the larger fans. The plants otherwise seemed healthy. No burning was observed. Growth stopped dead for the first ten days, and then resumed slowly. No stretch was ever seen. After two weeks the F>M plants were obviously forming male flower clusters. Not just a few clusters of balls, but complete male flower tops. One plant still formed some pistillate flowers, but overall it was predominantly male.

    It is strange indeed to see an old girlfriend that you know like the back of your hand go through a sex change. I'll admit that things were awkward between us at first.

    When the F>M plants look like they may soon open and release pollen, ( 3-1/2 to 4 weeks) move them from the main flower room into another unventilated room or closet with lighting on a 12/12 timer. Don't worry too much about watts per square foot; it will only be temporary.

    When the pollen flies, move your target plants into the closet and pollinate.

    A more controlled approach is to isolate the F>M plants in a third remote closet (no light is necessary in this one, as they are releasing pollen now and are nearly finished anyway). In this remote other closet the pollen is very carefully collected in a plastic produce bag or newspaper sleeve and then brought back to the lighted closet, where the target plants are now located. If this is done, be careful to not mix pollen types by letting the F>Ms dust each other. Avoid movement, or use yet another closet.

    Take special care to not let pollen gather on the outside of this bag- a static charge is sometimes present. Drop small open clusters of blooms inside and then close the bag at the mouth and shake. Important: next, step outside and slowly release the excess air from the bag, collapsing it completely, so that pollen doesn't get released accidently. Point downwind; don't let it get on your hands or clothes.

    This collapsed pollinated bag is now very carefully slipped over only one branch and is then tied off tightly at the mouth around the branch stem with a twist tie or tape, sealing the pollen inside. Let the bag inflate slightly with air again before sealing it off, so the branch can breathe. This technique keeps the entire plant from seeding. Agitate the bag a bit after tying it off to distribute the pollen. Don't forget to label the branch so you know which seeds are which. Other branches on this same plant can be hit with different pollen sources.

    If no lighted closet is available, the plant can be moved back into the main room, but- be very careful: pollen is sneaky. After 4-5 days, the bag is gently removed and the plant completes it's flowering cycle.

    Yet another method has worked well for me. I position the target plants in a non-ventilated lighted closet, and then I collect pollen on a piece of mirror or glass. This is then carefully applied to the pistils of one pre-labeled branch by using a very fine watercolor paintbrush. Care is taken to not agitate the branch or the pollen. No sneezing. The plant needs to be in place first; moving it after pollination can shake pollen free and blow this technique.

    Regardless of technique, at completion you will have feminized seeds. Let them dry for 2-4 weeks.

    About the chemicals:

    Silver nitrate is a white crystalline light-sensitive chemical that is commonly used in photography. It is also used in babies' eyes at birth to prevent blindness. It can cause mild skin irritation, and it stains brown. Avoid breathing. I didn't notice any smell or fumes, but ventilation is recommended. Be sure to wash the spray bottle well before you use it elsewhere; better yet: devote a bottle to STS use. A half gram is a surprisingly small amount; it would fit inside a gel capsule

    Here are links to some safety data. A Google search will bring up more information if needed.

    Silver Nitrate info:
    http://www.cdc.gov/niosh/ipcsneng/neng1116.html
    http://www.lions.odu.edu/~redwards/...%20solution.pdf

    For a realistic hazard level comparison, here is a link for the safety and handling data for Ammonium Nitrate, or common fertilizer:
    http://www.skcgulfcoast.com/nioshdb...ng/neng0216.htm

    Sodium thiosulfate is also a white crystalline chemical commonly used in photography; it is used in photographic fixers. Same general cautions apply, minus the staining. This formula uses the anhydrous type. Non-hazardous.

    sodium thiosulfate (anhydrous): 100 grams: $3.95
    http://www.photoformulary.com/Deskt...yID=28&langID=0

    Postage runs around $4. Fast service. Can be shipped to Canada.

    Have fun experimenting with this technique. Use it responsibly. There are a few good threads here at CW that go into the pros and cons of transsexual agents and feminized seeds. Read them. And most importantly, use STS with quality F1 strains developed by professional breeders for the most consistent results.

    A huge thanks to Fet from Spice Brothers Seeds for his help and advice in using this technique. I simply brought together available information from previous posts and tried my own recipe. I'm thrilled to share the results. Future tests will be done to adjust the formula so the molar ratios of the chemicals are correct, as specified by Gobgoober (thanks, Gob) but the formula posted here is completely effective.

    thank you. something new for me to work on. i like it.
    now putting all that aside (actually in my notebook for later study), i have a plant from last year that self pollenated. it yeilded 1/4lb of bud and about 20 seeds. are these seeds female? yes or no.

    Does anyone know if having a feminized seed origined female plant self pollinating do the trick or only a naturally sexed female plant that's self pollinated will produce feminized seeds? Actually I'm pretty much sure that the seeds that come from self pollinating will produce fems with the same genetics as their mom:they will probably be prone to having those little male flowers too. So if your ok with having a few seeds in an 18" cola, those seeds are golden. Maybe I'm saying osmehitng that was mentioned in that really long post full of links, couldn't read it (I just got back from amsterdam, you'd imagine how willing you are to read when you're burnt out like that), but repeating things never hurts!

    i thought actually there was an electromagnetic charge brought through the plants to kill male chromes, maybe im wrong, but im pretty sure thats the true way to make females
