Turning Males into Females????

Discussion in 'First-Time Cannabis Growers' started by Greenfingered1, Oct 23, 2006.

  1. Earlier this evening a fellow grower and I where chatting when we mentioned males, he swears that he had a spray that you use on early flowering stage male plants and it makes them female, he hasn't grown for a few years and says that he's going to dig it out for me if he can find it

    Anyone ever heard of something like this, NOT the feminising seed soak but an actual spray that can turn males into females like that????
     
  2. seems impossible to me it might go hermi but can is then grow bud
     
  3. Dosnt sound possable to me either, never heard of that.
    The seed soak thing dosnt work, my friend has tried it.
     
  4. You can't change the genetics of a plant with a spray, therefore you cannot change the sex of the plant with a spray. Some female plants can be stimulated into hermaphrodites, but you don't want hermies they are as useless as males.
     
  5. If you want to get deep down into it, it is possible to change male/herm plants into females, drawback is that it not easy at all and must be done in a lab with chemicals I cant even begin to pronounce.
     
  6. So what your saying is that it is possible, if it is actually possible then I can believe this guy had (or still has somewhere) this spray, he said that the plant almost dies for a while and you have to move the lights further away, keep the temps right down etc,
    this guy knows a lot of stuff about growin and has helped a couple of guys I know when they were doing hydro, I just don't see him often unless I have to fix his PC coz I built it and by fix it I mean clean it out completely and start afresh, so as you can guess it aint that often
     
  7. Similar to a convo I had with a friend a while back also, he just described a different method of doing so. I can't remember exactly what he said, but it sounded simple, something along the lines of snip, replant the roots, and voila. I'm doubtful to say the least.
     
  8. Another thread that is TOTAL BS. You cannot turn a male into a female, total nonsense.
     

  9. Look Spanish don't come shoutin your mouth in my thread

    Its not BS, I was jusr askin a civil question so if you can't keep a civil manner don't bother replyin to my threads
     

  10. That's simply not true, there is no scientific evidence to back up your claim. Search some reputable peer reviewed journals on botany and you will find that you cannot turn males into females or vice versa. With the right hormones and photoperiod manipulation you can create hermies but actually changing the sex of the plant 100% is not as yet possible according to the oxford university journal, which is an international highly commendated science journal. Assumedly with genetic modification it must be theoretically possible, but that sort of technology is certainly not yet available, infact, no data from successful research studies and trials on complete sex change in plants have been published as yet.
     
  11. He wasn't stating it as a fact, rather asking a question, so calm down on the BS..

    As for the question, it seems rather illogical and I've never heard of a way. I think if it were possible, it would be common knowledge amongst growers, due to the impact it would have on growing. So in short, do not get your hopes up.
     
  12. Well, I do not know much about plants, but I do not think plants have X and Y chromosomes like mammals do. Now, I'm not quite sure the genetic determination of sex in plants. I do know, however, that most plants out there have both male and female parts. This leads me to believe that all plants have the ability to have both (as seen with hermaphroditic cannabis plants). Now, time for the science. Since only one gender is expressed at a time, that leads me to believe that a certain protein or kinase is acting to control gene expression. In this case, it's acting to control the expression of gender. Now, what is probobly happening is this kinase or protein or even primer is either bonding to an inhibitor site, or activation site on the DNA. Now, for arguments sake, we'll say it's an inhibitor site. Depending on what chemicals and hormones are present in the plant, will depend on whether or not this macromolecule will sit on this site. Now, the hormones and chemicals for a male plant are present. This will allowe the kinase to be phosphorilated by ATP, causing it to release from the inhibitor site, thus allowing RNA polymerase to come in and allow for the expression of that gene. Now, at the same time, the presence of these chemicals and hormones causes an inhibitor to bond to the gene that controls the female gender. So, theoreticly, if we spray the plant, or somehow introduce new hormones and chemicals to it, we can alter it's sex. The macromolecules in the plant will recognize the different levels of these chemicals and hormones, and could cause the kinase to bond on the inhibitor site for the gene that controls the expression of the male sex, and allow the inhibitor on the gene contorling the expression of the female to sex to phosphorilate and change its conformation, thus no longer sitting on the inhibitor site. Now RNA polymerase comes it, transcribes the DNA into RNA, the RNA then leaves the nucleus, travels to the ribosome, builds a polypeptide chain, which then creates a protein, and voilla. We have turned a male plant into a female plant. Now as I said, I'm not entirley sure about the genetic makeup of plants, but looking at the facts, this is just one possable theory. I have a bunch more floating around, but I probobly lost most of you in the first couple of sentences.
     

  13. Now that is about the best response I coud have expected, I understand you perfectly and thats sort of what I was thinking just not so scientifically LOL
    Hell we can supposedly manipulate an embryo to be male or female so there probably is a way to do it, just nobody has really worked on it because of the plant that its OR because it has to be done under such strict circumstances that its just not viable

    I also think that you could be right in saying if it was possible that it would be common knowledge, that could also be because of it being too difficult/unreliable to be viable and would explain it not being common knowledge


    Thanks for the comments anyway, I'm gonna chase this guy who told me about this stuff and see where it goes, if he still has the stuff and I get my hands on it (or he doesn't and I don't) I'll let you all know what the truth behind it is
     
  14. ccgfan, cannabis does express through male and female XY chromosomes, genetics does determine the sex of the plant. This quote from Euphytica (The sexual differentiation of Cannabis sativa L.: A morphological and molecular study) might shed some light on the subject.


    But whether cannabis can be manipulated in the way ccgfan suggests, is in my opinion wishful thinking ;) However I would love to hear of any studies or trials, so Greenfingered1 I can't wait to hear your results if you get hold of this fantastic sounding spray.
     



  15. If you don´t want people to reply to threads then don´t start them.

    And if you insist on asking total BS don´t be surprised if you get a dusty answer.

    You can´t turn a female plant into a male any more than you can turn a woman into a man.

    Neither am I impressed by pseudo-scientific claptrap written by someone who can´t even spell the long words.
     
  16. Your post was very informative. Since cannabis does express gender through XY chromosome, then it still might be possable to change male to female (but it would still be very very hard). Males are caused by the genes expressed in the X and the Y chromosome. Females however, although having two X chromosomes, only have gene expression from one of the chromosomes. The other chromosome shrivels up and becomes what is known as a Barr body. So, if the Y chromosome of the male can be turned off, leaving a single X chromosome, then it might just be possable.
     
  17. Wow, spanish, you are a very hostile person. It was a completely legit question on his part. And speudo-scientific claptrap? I guess you never went to college. Try actualy opening up a biology book. I didn't just make this stuff up ya know. And is spelling really a sign of whether I know what i'm talking about or not? No, not really. I'll admit, i'm a horrendous speller, but I know what i'm talking about, and I'm educated in my field. So unless you majored in biology, which it doesn't seem as if you did, then you might as well keep your mouth shut and let people think you are a moron, then to actualy say something and remove any doubts there may have been.

    Next time you post, make it a constructive post. Not just go critisizing people. We are fighting enough people out there who are anti-marijuana. We don't need to be fighting each other.
     
  18. Rattled a few cages here.

    But you still can´t turn a female into a male, nor a male into a female. Period.

    You can make a female produce pollen sacs by stress or by chemicals, but it remains genetically female.

    And who would want to turn a female into a male, anyway?
     



  19. Hey, ccg, I just read again what you actually wrote and fell about laughing.
     
  20. You can make a MALE mj plant produce female flowers but it's still a male.

    Use gibberellic acid which is a powerful plant hormone. It will then produce both male and female flowers.

    But it's still a male.

    And wtf has Biology got to do with growing?
