Help me and my gf be successful at our first grow

Males usually show their sex before females, so you are probably left with girls.

As Light it up says ^^^^, it's very important at this point to make sure you don't bring bugs in with the girls, it could ruin you down the line.

You can try super cropping your tall plants, you can break them in half by gently bending them...you need to look up the method, it can be beneficial for your yield too. Or simply cut in half. Sounds scary but it doesn't really hurt that much, at least then they would have a chance to make it in the tent.

Here is a vid on super cropping to start with..keep looking, there are lots of good tutorials out there. http://www.youtube.com/watch?v=2FmXHhKFA5U&feature=player_embedded

4 and 6 were females...hopefully them's the one's you saved. The other were so obviously male though, try to catch them sooner on your next grow guys hehe

The first 2 pics are obvious males
