Re: What is the Percentage that a "Regular" (non-feminized) Seed will be Feminine? [Re: TrueHerbCrystal] #351887 - 01/22/10 12:23 PM (14 years, 11 months ago)
Well in nature the ratio is about 2 females for every male plant. Reason for this is that one male can fertilize tons of female plants. In other words if there are more females the plants you get a higher number of seeds which is a higher number of offspring.

This is definitely true, and one of the easiest ways to help induce a female is to flower it from seed. It has been all but proven that this can lead to more females than males. As an experiment I once took 6 regular seeds and gave them 12/12 from germination. All 6 ended up female. Even if the odds of female truly are 6/10 for a regular seed, the odds of taking 6 random regular seeds and getting 6 females would be 6/10 to the 6th power = 0.046 * 100 = 4.6 % , or about 1/20. So I could just been lucky, or it really works. This isn't a large of enough sample size of course for an accurate statistic, but I have bought the theory ever since then. There are tons of reports using it that you may be able to find online. However, you cannot create odds for male or female with marijuana seeds, as they have a more complicated mechanism of sex determination. Decades ago it was thought that cannabis had a dioecious sex determining mechanism, like humans, meaning two chromosomes XX or XY. Now it is often referred to as an X:A system, meaning the second is a variable and isn't established when the gametes meet. There are other chemicals that can induce sex changes, I remember gibberellins or gibberellic acid is used to induce males, I can't remember the one that induces a female, but you could google that if you are interested.
Well close on the seed thing but flowering right from seed won't induce females. There are several strains that cause of their flowering times that many people flower right from seed. Now on the chemicals that induce sex changes that really isn't the case what they do is block a hormone. There is a hormone that tells the flower that it is to be female what Gabrillic acid and sts (even better) do is block that hormone. There is no known way to add the hormone to a plant to induce female flowers.

You are so close it's not funny. Now there is no way to add ethylene to cause more females. Ethylene is the hormone I was talking about earlier. What gabrillic acid and sts do is block ethylene to cause the male flowers.
The environmental factors that influence gender are: (These are claims by the Dutch Passion Seed Company)
* a higher nitrogen concentration will give more females. * a higher potassium concentration will give more males. * a higher humidity will give more females. * a lower temperature will give more females. * more blue light will give more females. * Fewer hours of light will give more females.
