you have to vegetate your plant for atleast 5 weeks then you can go into 12/12 to start to flower(tell if male/female). or you can vegetate for more than 5 weeks until you see pre flowers

how large does a marijuana plant have to grow before it can be sexed?

green.... as soon as you switch the light cycle to 12/12 (12 hours of uninterrupted darkness) your plant will most likely show sex in 14 days.

You can do this one day after germination or you can wait 5 years.. it is up to you...

In most cases, there is no need to veg for more than 14-30 days to grow a GREAT indoor plant!

The plants in this book were vegged for only 14-15 days and yielded 2-3 ounces....

check out the CFL section on these message boards.. they have great info on veg and flowering cycles

is there anyway that you can help the plant become female only?
Dutch Masters has a product called reverse. Its supposed to turn males to females. I have never used this product, It sounds to good to be true
but its out there.

ill scan the info just for you, or better yet i'll see if my digi camera can take a good pic of it

there are other ways to also promote feminization, you just have to be KNOWLEDGABLE of them

....i guess you didn't know that if you have enough money, you can pay to have a doctor or whoever performs the procedure to promote a certain sex of a baby in a womans stomach

you know that right? or am i just in scifi land again?

i think you can do that... but thats like bio-chemistry and genetic altering... not changing anything with the mothers pregnancy.... \


ive heard of the 16 8 theory before and it just dosnt make sense too me how does an extra two hours less of of light = more females?

the banana method is another one and i think that has more evidence behind it than simply switching the light schedule... think about it if it was ABSOLUTELY certain to give you a higher ratio of females then everyone would do it and it wouldnt be a such a "secret"

all your doing is robbing your plants 2 hours of extra light

if you want a high # females give your plants the perfect growing environment, make sure they're light schedules whatever you keep them on don't get screwed up, make sure you have complete dark for "night time" and don't stress your plants out and you will have lots of girls

well the most dominant is the male, because male overall is dominate/strong; regarding to survival. During germination seeds prefer no light over some. With this being, it is more probable for the males to surive into seedlings rather than female. If you cut the hours of light by a couple and more females survive. It doesn't impact the already would have been amount of males, just an increased amount of female survival.

hope that make sense, anyways here is the piece

Hmmmm.... I always thought it was the male that determined the sex of a human child. XX vs. XY is determined at conception so the egg is always X. It could be that there's some way to make the uterus more friendly to Y sperm but I've not heard of this.

I found this surfing one day around the bottom of this link, just above the "books" section. Cannabis Growing Guide Part 8 Hope it's true.

"A Russian study showed that seedlings with at least 4 inches of soil to grow the tap root were more likely to go female. The source I'm quoting says This may be why some farmers get female/male ratios as great as 80/20."
