no pics..but i'll fill you in

Ok, so my plants are about...say, a month and a half? I've tried to get some pics but unfortunately, I cant find my pos camera. So I beg you cope with the information I'm about to give you ..I just want to know if my plants are all females for sure or not...
well ok..
The tallest stands at 16 1/2 inches now, med. is 14 inches, and smallest is about 11 inches[ this is all with an infrared heat lamp about 15 inches above them, bad lighting..I know looking into fixing that soon] ...
I'm about to seperate them because I put them all together in this very large pot..each about 5 inches away from the other?
Anyways, I'm not so sure if they're all females...
I mean, I see little hair things, but on one of them the medium one, there is this little...little green thing like, smack in the middle of it right near the top..it has those hairs all around it and on the rest of it near the beginning of the branches and all you know? But I thought maybe that might be the pollen sack or something...note this is my first attempt to grow jane, but you know..I just want what's best for my children. I'm sure you understand ! Well, I was just curious on how exactly I know for sure if they're all chicks...I know how to check, but...gahhhh I'll try my best to post some pics asap! its just eating me away right now

Oh, damn.

They're all in one pot?

Well, unless your god i think they're fucked. ALL the roots will be tied in together now, you'll have to rip them to separate them, causin stress and stunting growth.

The females have WHITE hairs, the males have balls. If the plant has both, its hermie, therefore pull the ball off and flower like normal, pulling all the balls off as you see them grow.

Damn man... All in one pot? Thats a shame.

yea man... good luck... if you see sacs kill it by chopping it from the bottom.

This is what your females should look like.

ahh shit..well thanks for the info..i just wanna see what comes out of this
