Female seeding

Its been a while since i have been in here...so long i lost the password lol....anyways...its been a while but when i was active on here, there was a thread for seeding female plants to get only female seeds

from what im seeing now, i see most say no, you have to have a male to do so

however, from what i read long ago...last year sometime....18 months ago maybe...there was a technique to playing with the light during the dark period of the budding stage...and as i cant seem to find the old thread, i was hoping maybe someone could help point me in the right direction of where it might be or if it really does not work....would like to know before i bother messing up the light cycle...but need to do it this year if i can lol

thanks in advance to any help as it is all appreciated ;O)

ok so i found a couple things looking in the hermie section as it seems that is what i would be doing. But is there any way to get just female seeds off a plant ? i do have a male going so i could just go that route, but who wants to play the guessing game that entails ? lol

They're called feminized seeds, snake oil IMO, however if its in your interest try using gerabolic acid, or colloidal silver. They will induce staminate flowers that can be collectedfor use. Light stress works however if ur running multiple plants u run the risk of them all following cue if you don't have a seperate space. Fem'd runs way too high of a risk for mutants and hermies imo. But if ur gonna do it look into the above mentioned techniques

well we have an outdoor grow going and we topped them....rooted the tops and are just trying to get some without crossing anything ....the males i have are amnesia haze...and honestly this is our first try with them, so im not even sure if i want to cross it with jack flash or the northern lights crossed with haze...but thanks for the info...i greatly appreciate it
