So I got seeds that are all about 6 inches tall in red party cups, I have 8 and am going to give 4 away in a week, is their any way to make an educated guess on witch ones are females??? maybe keep the shorter ones??
You have 6" seeds? They gotta be the biggest seeds I ever heard of. Damn. Seriously though, no, there is no way to tell from seedling what the sex is. Good Luck.
i'm guessing he means clones. don't give any away until you know what sex they are, and obviously don't give away the males (unless requested). i'll do a little copypasta if you don't mind! Female Pistils - notice the sac and the feathery frond-like structure. Usually after five days to two weeks you will begin to see a pair of tubular nodes. Hopefully they will have white hairs protruding from them as this denotes a female plant. These little hairs are known as pistils and they are the first sign your plant is flowering.
