Self produced feminized seeds?

So last summer I had about 20 clones that got really stressed from the summer heat and after weeks of nice promising colas they suddenly exploded with seeds everywhere!! At first I was very upset, but I soon realized that I will now have plenty of seed stock of a kick ass strain! The seeds came out looking awsome! I have read that this is a way to produce feminized seeds. I have other strains that I really need to get some seeds out of but I dont want to stress all them, just one or two. Anyone with any info would be greatly appreciated.

Anyone????

hey, well of what ive learned about feminized seeds, plants always think they are alone on the world and if the polen doesnt reach them the self polinate theyrselfs, im not sure how, why or when this happens but it has happend to a lot of ppl that i know, only thing you can do is get 10 seeds flower them to sex then you get the female rate say 9/10 are female then they are practicly feminized, good luck.

when the plant gets stressed and has flowered past its maturity there is a way to get feminized seeds.... go look up the seed section of these forums you will find your info there
