i would not suggest trying to stress your plant for seeds, the seeds will hermie out, i have a few diaries i have made seeds in, but i am using photo strains, i tried autos but because they are plants that are made to be automatic, they are very hard to do, you will have to grab or make some spray and you will have to spray one plant before it shows signs of sex, like right around the 3rd week in veg right before flowering starts, you can make the col. silver yourself or you can make the silver thisolate spray yourself, i have made both before and both do work, i can send you the recipes if you want or you can find the col. silver on ebay and sometimes the other. you can stress out a photo to make seeds yes but you have the extra time to do that where autos are on a time line to veg for x amount and flower for x amount until the plant is ready to be done with her life. i have mad seeds using males as well as i made female seeds using the spray, so if you have any other questions just ask
