I've mostly read about males growing bigger too, but in my first grow I had both females and males of different sizes, all were started at the same time. The two biggest ones (of equal height and shape) turned out to be female and male and they looked almost identical except for the preflowers. So don't be so quick to throw out any plants that grow like a monster and take forever to show sex, it's still a 50/50 chance.

Another characteristic I've read about, and noticed for myself about the males during veg, is they really smell like cannabis. The females had no distinctive odor.
GreenDestiny Reviewed by GreenDestiny on . Male vS Female? are there any factors that may determine sex of plant earlier than the pre flowering and flowering stages? a not so expierenced friend heard from a experienced friend that females tend to grow faster/bigger from sprout is this true? are there any other minor things that make give off the slightest guess as to female/male?
