But the topic of the thread, and the post I was commenting to was speaking to the number of females from ten seeds. I assumed this meant one package.jojajico said:

I was hoping for 6 females but expected at least 5 I admit. my buddy germed 10 ww seeds same time as me and lost two seedlings right off the bat and still got 4 out of 8 female so i thought maybe that 50/50 ratio held true. I will plant at least 20 seeds next grow and hope for 10 female. we'll see how it goes. thx guys 
I have to agree here. Me and a mate had a similar argument. He said if you keep you soil warm you will get 100% Females... I tried reasoning with him that the only way to get 100% females is to buy feminised seeds. At best it MAY increase your odds ever so slightly, still the 50/50 ratio holds true... He wouldn't listen, so i gave up. Now he's running heaters next to his bins....jojajico said:

my turn.
erm,
hmmm,
you are more likely to get a picture card when playing blackjack than any other card out of the deck. Yes, but only becasue there are only 4 of every other card, and 12 picture cards. Yes you are more likely to get any ratio other than a 50:50, but only because there are more of them. Ignoring hermies, non sprouters and sickly plants killed off before sexing, the overall average of non feminised seeds around the world, will be roughly 50:50 allowing for variation over time, which after all the time has elapsed, should then make the average over time around the world 50:50. But yes, at one point in time, in one place on earth, in one packet of 10 seeds, there may be more males, more females, or exactly the same number of each, even if that number is 0 and you have a pck of hermies.

tru dat, even fem seeds arent always 100% female? they say they are but its really something like 99.9999% i feel bad for that one guy in a million that hinks hes getting all fem seeds and ends up with a seeded crop.Grownz said:I have to agree here.

this is from cervantes grower's bible and is data collected from dutch passion
increase female to male ratio by:
increase level of nitrogen, lower potassium, high humididty, more blue spectrum light, and fewer daylight hours all during the first two weeks after germination.
you wont get 100% femals but it should help your ratios a bit.
because your just as likely to get all males and all females as any variation in between its impossible to say
50/50 lol ...like us : ) everythings all 50/50
Peace

Just to throw in my 2 cents, I haven't studied the specifics of mj genetics, but many species (especially plants) have vastly different karyotypes from humans, so the basic concept of xx and xy does not always apply the same way. I'm not sure how many sex chromosomes there are in mj, but some plants have four copies rather than 2 as in humans. That being said, once development begins, just because you have a certain set of genes does not mean they will be activated, this can often be manipulated by environmental factors. In humans, all embryos start out female (sorry guys, it's true) and it is the specific activation of the y chromosome later in development that produces male children. I have read that certain environmental factors such as day length, nitrogen, soil humidity, etc... can influence seedlings one way or the other (check out Cervantes' "Grower's Bible" for more specific info). I cannot say for sure if his info is legit, but speaking as a molecular bio major, I can say from my knowledge of genetics that it is within the realm of possibility to influence sex in some organisms.
I think if environmental factors were an issue, then feminised seeds would not be possible. In general seed populations, there would be a higher concentration of one sex or another in each growers garden during each round of sexing. The fact that peeps find a wide range of ratios, including 50:50s, suggests to me that environmental factors aren't an issue. In crocodiles, the egg temps have to remain in quite a narrow temp range in order to produce males, therefore reducing the ratio of males to females, but nests tend to contain a high proportion of the same sex, due to the temps being fairly consistent throughout each nest. I suspect the same would be true in each garden if environmental factors were relevant.

things that make u go hmmm....
there are a few animal species that can change sex throughout their life time.Grownz said:The same is true in some speices of lizard. Possibly many types of reptiles.
Then there's the frog that can change sex!!!Although this is said to be because of a commonly-used herbicide polluting their habitat.
This is interesting, does anyone know the details of animals that change sex, I'll do some searches, but if anyone has a good starting point. For instance, which animals, frogs, anything else? Do they all change from girls to boys, or do some change from boys to girls? Or is it the other way around?
Oh ya I have planted about 10 to 12 packs of seeds(The 10 packs) not all at once and I most always get 2 males out of 10 and some times one of the seeds dont germ. It happens that way all time for me No more No less and these are nirvana seeds. Only time I got diffence results is when I planted 10 KC brains seed and none germed. But I have only got 2 male out of every grow I ever did from seed
what about more nitrogyn during veg? I read somewhere that will increase the number of females? I was always afraid to go to crazy during veg because i was afraid of causing stress and hermying the plants. I just planted 5 northern lights and got 3 females... now i have 4 hashberrys going. I would be extremely happy with 2 females.
GMT, from a quick search it seems fish are the main culprit. They seem to do this when the reach 72% of there maximum size. Search "Animals that change sex" and "Size matters for animals that change sex"
Remember Jurassic park? They thought they had all female dinosaurs only to find out the DNA they used was from an african reed frog i think.

Well... now that the sex change can of worms has been opened...
Almost all cannabis plants are hermorphaditic to some small degree...
Even though a plant expresses female flowers under most conditions, the fact that there are conditions which cause male flowers to be produced means that both potential sex chromosomes are present...
Now if the seeds are all to some degree both male and female, and specific environmental conditions can cause more of the seeds to express as female or as male... Then wouldn't the plants which had to be influenced by specific conditions to express as female be more likely to reverse under variable conditions?
Would not the seeds which express female in an environment which is likely to cause a higher male ratio be more resistant to reversal?
If all the seeds in a pack are to some degree both sexes, what is the average m/f ratio?
