    ive heard there are a few ways to fem your seeds.. but what is the most guaranteed method? and what is the science behind it?

    see the link in my sig. There's ~3 different solutions you can use, but the most common is colloidal silver. Long story short, you just keep spraying it on a female plant (or just a single branch even) for a few weeks, eventually it should produce pollen ... any seeds created as a result of this pollen are feminised. You can use the pollen on the same plant to 'self' it, but usually the pollen is applied to other females. I'm not sure if Giberellic Acid or STS are more successful than colloidal silver, but it's well established all three work well

    Quick question. What’s the difference between the “self” pollinated plant from colloidal silver and a hermaphrodited plant?

    define a "hermaphrodited plant"? this all goes back to whether the heritage is monoecious, dioecious or polyecious ... some plants have a natural genetic lean towards producing hermaphrodites. But that's another matter, as most people create feminised seeds using plants that don't have monoecious or polyecious heritage

    I use rodelization for a 100% female seed experience. google soma, rodelization

    thats surely the least efficient method though - it requires you taking a plant welllll beyond its harvest time, and nobody seems to know exactly how many strains respond to it (so you could be wasting weeks for nothing), but seemingly a lot don't. It seems to rely on the plant having some self-preservation mechanism of sorts where it realises "i'm dying, might as well self-pollinate", but there aren't too many people on the internet purporting it as the way to go. How many times have you used it, and how many strains, and what were the results? there's still a scant amount of info about published results on the web unfortunately, I guess because it's just far more convenient and faster to spray the plant with colloidal silver, GA, or STS, so I struggle to find how 'rodelization' is ever going to offer much

    I use this technique most months since I learned of it. I've grown every cannabis cup winner from every country through the years until just a few years ago. All of them show the same expression in my rooms at late harvest, like 2/4 weeks after my normal cut, I leave a cola for this often. I cycle 20-30 different strains/year and havent found one strain of marijuana that didnt show a late flower banana at the top of the cola.I've also never had a male or dud result. I keep chems and hormones separate from my medical garden and this fits my organic bill every time. Free fem seeds, no chems, no fuss, just cannot be true, too easy I suspect.

    that's very fkn cool data to hear you've had excellent success with it mate!!! :) you're more patient than me tho eheh

    btw in regards to "no chems", colloidal silver is literally just the element silver suspended in water via electrolysis, so there isn't really a "chem" thing in that regard. Also, we don't consume the sprayed buds, we just use the resulting seeds :)

    I've used colloidal and the others too and that teris mist spray all worked as advertised.

    I think I was confusing rhodelisation with hermaphroditism.

    Hey chem, by doing that are you still in the gene pool for multiple phenotypes? Like the seed the original female you did this to was.

    I havent experienced many multiple phenotype seeding hunts in seed packs really
    or when using my own seed productions. Like the Raindance I love the pack had two different types and I chose one. Since then the seeds I've made have been representative of that one I chose to keep. this is typical of my past experiences also. leaning to the answer "no" but I really dont know.
    I always wonder about genotype vs phenotype

    Gotcha 6 of one, half dozen of the other.

    its a really good question, like am I limiting when I self a plant, or when I use this late flower pollen ? I'm no breeder
    though I do make records (seeds) of what I'm doing and I grow out handfuls of all.

    I think I'm going to start playing around like that. If anything a batch of s1's is a good way to keep a strain around.

    that Tiresias Mist stuff is apparently just colloidal silver though, heavily overpriced at that especially for such a small amount!

    So if I have a pack of rev seeds and find a female I like I can not self pollinate her. I can get her to pollinate and take a clone of her to bread to herself ?

    Was hoping to be able to find a good fem and just make seeds from her.

    to perpetuate the single female plant you have some options.

    yes you can self the females, you could clone them too or

    allow her to mature past harvest date until single yellow bananas appear on the cola, use this pollen to pollinate another female ready for the pollination, careful planning is good=female seeds
    you could also initiate a male expression with silver or chems and use this pollen to pollinate itself or another ready girl
    you could allow a male and female to flower together and the female will be pollinated.
    all will make seeds.

    yes you can self-pollinate her. A female is a female. All you need is 1 female, it doesn't matter if that female was grown from regular seed or feminised seed. Apparently if you want to create your own stable strain it's best to work with regular genetics though, the reasons for this are not clear to me though and I'm not sure how much scientific weight they have, but if you're just like most people - a smalltime home grower wanting to create feminised seeds, then there is absolutely no problem using a female from a feminised seed as the basis for the feminisation.

    I just wish we had more science from the scientific community about this, but until it becomes legal and easy for scientists to study cannabis we still have to rely on things like forum members who've read from other forum members who've read something on the internet that came from other forum members, etc. It's INSANE banning scientists from researching this in 2017+ simply because of weird legal changes in the 1930's. Talk about a hangover. :(
