that sucks. i was growing two and both turned out to be males. sucks when all the work for the last month was to no avail. at least you got two of them. you should keep the best of the 4 males and empregnate your females manually with some of its pollen. then youll get even more seeds to work with. but you cant just let it pollenate the plant or youll get nothing but seeds. just collect some pollen from one of the mature sacs. then spread it on some of the lowest buds on the plant. or you could also just remove the plant as soon as you see the first tic bit of pollen.
