Sexing Method; Fact or Fiction?

[jon420]

This post is in regards to a post I found a while back that I cannot find anymore. I believe it was about sexing from unknown seeds and not clones.

The post indicated that "sex" could be determined well befor pre-flowers. It was said that a "male" will not produce any purple in the stem system, or any sort of purple veins. It was also said that a "female" will always produce purple in the vein system. The purple may appear in the whole plant, just the stem, just the the leaf shoots, or a combination but there should be purple. So far, from what I have seen, this myth may be real. I also understand that "purple" in the veins can mean problems but I have yet seen a purple problem occur.

Remember:From seed, not clone.

Does anyone have any physical proof of a female without any purple at all?
Does anyone have proof of a male with puple veins, that did not hermaphrodite and was never female?

I am in the process of trying to figure this out but I wanted to se what everyone else has to say or offer.

Thanks

Aloha,never heard that before but sure would be stoked if thats the case.Four out of six of the ones I have going now have purps on the stems.I assume this is what your talking about.Waiting for these to show signs now, I read about placing a bag over one branch for 12-12 to see the sex.Think i'll try that and see if what you have read has any merit.

I think I may have been the one to post the original.

I still believe that when first coming out of the soil, the red stems are going to be female. Later they will just get green but as the plant gets a little older just the leaf stems will get a dusting of red on the upper surface of the stem. To the best of my feeble recollection I have never had a male that had the red discoloration.

This is not an every time thing, just mostly. Currently I found one that looked male on sprouting. It is a female. It does not have any red at all in the leaf stems. So, my theory is not perfect just something that is more common in females.

Yes the purple can also mean deficiency.....but not at the itty bitty first stage of life when it is living off the cotlydon (sp?).

I am not fool enough to stick my neck out and say that this is perfect, just a theory and observations of growing over 30 years.

I was hoping to find the original owner of this theory. Thank you for your theory by the way. So far, your theory has been correct. I also noticed a brite green female once that did not show any purp except for where the stem of the leaf actually met the leaf.

I have still yet to see a purp male, unless it hermied some how!?!?

I will stick by your theory until proof it is wrong, it has been 100% correct thus far.

It is a female. It does not have any red at all in the leaf stems.

Was there any purp anywhere within the whole stem system??? Or was is completely green without any purp at all???

Thanks

So far, it has shown no red. It goes to flower room in next week or so.

I might add to this that hermies will get the red/purp too.

Well it is nice to know that others notice the same things as my theory. Appreciate the feedback

I have seen plenty of purple hermies in my day but I have yet to see a totaly all green (no purp at all anywhere) female. Until I see a fully mature female without any purp, I will continue to stick by and study your theory.

I just planted 2 females and I they both have the purple stems.:thumbsup:

BTW, for those that dont know...

I allways buy feminized seeds & I used to wonder how they knew before
hand if they were females.
It seems that female seeds have a perfectly round volcano type scar from when they came off the stems.
Males seeds on the other hand have an irregular distorted scar.
I put this to the test and found it
to be 100% accurate, so far.
