& 1 of my plants have hairs coming 4rm the very top of the canopy.
Thats a female 4sure
Good 4 u... more light = bigger yield..
As far as the hairs coming out at the very top, that's not a sign of sex... You need to look really close at the stem, where the leaves that are branching out from the stem meet (nodes)... You cannot see it with the naked eye, it requires something that will enable you to zoom in and see the tiny little hairs or the tiny little balls...
You can find this info everywhere on this site w/ pictures of what a female plant looks like as compared to a male plant.. If you're having trouble finding it on here, just goto google and type in "sexing a marijuana plant".. Results should bring up some posts from RIU..
You'd be smart to figure this out before you get too far along and the males pollinate the females, causing your bud to have seeds in it.. If you pull the males before they pollinate the females, you will have seedless buds..
