I can tell they are indica or indica-dom by the leaves, but not much else. Two of them grew abt twice as tall as the other 2, but I don't know if they are a different strain, or if they are taller because they are male. The leaves are similar enough to make me think they are the same strain. I'l post pictures tonight after my lights come on, but my camera will not give useful pictures of the primordia forming now on the plants. Typically, how long under 12/12 lighting will it take for male flowers to be identifiable as such, and how long before pollen could drop? I've only grown from clones, so have never sexed a plant before. As these plants are in with my main grow which is 2-3 weeks from harvest, I'd rather take them all out than risk any chance of pollination. If my window is only hours at some point, I'll just tear 'em up now. I check my flowering plants at least twice a day, so if I can be assured if identification at least a day or 2 prior to any pollen being available, I'm ok. Thanx for any info you can provide.
Well if this helps my man, iv had a few males and sexing is easy after ya do it once. As far as pollinating your girls, the balls need to mature some what to offer pollen to your girls. Also, iv read that if you keep them wet they wont pollinate, which you probably know. As you said 2 were bigger and males grow faster, but could be some good stuff. Could be an opportunity to create an interesting cross? I grew a male for 2 months outside and the balls never opened. Of course i moved it once i knew it was male. I did get two seeds out of the plant that was close to it, but it was a good size plant, so no big deal. I think you would catch them before any pollen would get out of the balls. I have a couple pics il post that has helped people when asking about sexing, i think might help to see the sex up close and personal. The pro's will be chimming in soon too.


If you right click and open link in the first pic i marked sex with paint program which can be seen earlier with a 30x microscope, or jewelers loop. Second pic you can see the balls that are not open. It was about two months old.

Headshake gave me this link for the perfect tool to identify male/female, he said it was about 13 bucks, so not to much to spend.
