I found something very interesting. According to this study you can get 100% females from marijuana seeds by growing them in a nitrogen-overdose soil, but they will wilt and die shortly after sexing. I wonder if this could be used to increase your female-to-male ratio if you were to give a good flush after several weeks. Also the seeds grown in a nitrogen deficient solution were all males. Here's a link. http://www.google.com/url?sa=t&sourc...dOwv6EpL2mYbTg
