Once you flip the switch to 12/12, you should be able to tell within the first couple weeks. Some will show if they veg for enough time also. Check out this short little thread. It has a couple pics of what a male and female look like. http://boards.cannabis.com/outdoor-g...ve-plants.html . Being new, i would suggest reading everything you can get your hands on plus some. Good luck
