i heard the best way is to use real pure silver, then put it in distilled water and run a current through it, then the silver dissolves into the water. Then spray this silver on your plants with the water, it will cacsue them to herm.
There are other methods, I forget which, but they involve harsher chemicals and I wouldnt reccomend it becasue chemicals are grose especially if you spray them all over the buds your seeds are gonna be coming out of
google everything do not trust what i just said.

this is from the growfaq. its a pretty good article or whatever you want to call it
What are all female seeds and how are they created?
Contributed by Mr.XX and TheSiliconMagician:
This is the strategy of Mr. XX, a Dutch breeder, for creating all female seedlines from slight hermaphroditic pollen. What he does is put the lights on 12/12 for 10 days. Then turns the lights on 24 hours, then 12/12 again for a few days, then back to 24 hours for a day, then 12/12 again for a few weeks.
If he does this and no hermaphrodites come up. He has found a 100% XX female that cannot go hermaprhoditic naturally. He says that your chances of finding a 100% XX female is vastly increased when using Indica genetics. He told me that the more Afghanni or Nepalese genetics the plant has, the better the chances of finding a natural XX female. His
exact words were "Where did mother nature give weed a home at originally?"
I tried to get him to narrow it down to a ratio, but he never specified just how many plants per are XX females his exact words are "plenty of XX girls for everybody" and that is all he will say on the subject. Only that it takes alot of time and alot of plants to find that one female.
He then uses Gibrellic acid. 30 centiliters of water with 0.02 grams of Gibrellic acid and 2 drops of Natruim Hydroxide to liquify the Gibrellic. Then applies as normal and creates the male flowers. He has gotten down to the 4th Generation with NO loss of vigor, NO genetic deficiencies and NO hermaphrodites. He claims that the plants are EXACT GENETIC CLONES of one another. Complete sisters. Basically it's clone from seed instead of from normal cloning methods.

Gibberellic acid, pH stress, light stress, and fertilizer stress can forcibly stress the plants to turn hermaphroditic. If you know the strain then you can find out the proper method, since some strains are more/less sensitive to the different stresses mentioned. Considering that you're looking into making herms, I would assume that the seeds are feminized.....
I personally would advise against it. It is a relatively advanced technique, and it is concerning that breeding with hermaphrodites (especially with femmed seeds) have a tendency to pass on that hermaphroditic trait in your entire seed crop. IMO its a really delicate scenario, since your crop from that plant could be wasted on seeds that have a chance of growing male branches if any significant stress is placed upon them.

Screwing with the light cycle during weeks 2-4 of flowering (Light Stress) always works for me. Could even be as simple as shining a bright flash light on them for awhile during their dark stage each night, for you outdoor guys. Did a seed grow awhile back, and the resulting seeds from the herm'd females that pollinated each other, have all produced 100% female plants so far. Out of around 25 plants that have grown to maturity thus far, from that seed run, not one Male or Herm has came out of that stash of seeds. I keep the plants in a perfect environment with zero stress put on them though, so that may be a reason why none of them have ever herm'd on me. Seems to work though, so I'm gonna be trying it on more strains in the future, for seed runs.

...I've never done it, but dance the photoperiod around. I've read alot about it, just not my bag. I've also read that you can simply continue your plant in flower for an extra long time....in other words "over flower" a plant. Leave it in bloom longer then projected.

Not true. If you force a female to turn herme and its not genetical than your safe. Thats how seed banks do it.

Run a current though it, interesting.

Thanks!
I'm gonna try messing with the light cycle and If that doesent work gonna try the acid.

not true, your seeds will all be female....or hermie. its not gaurenteed that way. thats why the other method exists.

How do you get female seeds that are hermie free?

look at the 3rd post in the thread. lol, I already put how.

ok so using Gibrellic acid to (force hermaphrodite) dose not cause the harvested female seeds to turn hermaphrodite, because its not genetical. That was my point before, which you said was "not true". lol.

found this in the "F.A.Q." tab, hope this helps... How can I get my plants to produce femenized seeds?

How can I get my plants to produce femenized seeds?
There are two methods that I am familiar with; Light-Poisoning, and Gibberellic Acid Treatment, both forcing female plants to produce male flowers and pollinate themselves. I have employed both methods, and both have yielded satisfactory results.
NOTE: YOU MUST START WITH FEMALE SEEDS/CLONES TO ENSURE THAT THERE WILL BE NO MALE CHROMOSOMES PRESENT.
LIGHT-POISONING METHOD: During the first three weeks of flowering, turn the lights on for an hour during the middle of the dark period. That is, 12 hrs. on, 5.5 hrs. off, 1 hr. on, 5.5 hrs. off, and repeat for the first 3 weeks, after which you may return to the normal 12/12 light cycle. This causes a plant to go "hermie" and pollinate itself, as well as any other female in the room. You must use plants originating only from female seeds or clones to ensure that no male chromosomes are present. The resulting seeds will produce NO MALE PLANTS!
GIBBERELLIC ACID TREATMENT: Select your favorite female plant and spray it from approx. two feet away (first under the leaves, then on top). This must be done 2 weeks before the plant is put into the flowering light cycle, thus the need to start with female seeds/clones. DO NOT SMOKE BUD TREATED WITH GIBBERELLIC ACID! Spray the plant again after 2 weeks have passed, and place it under 12/12 lighting. This plant will "hermie" and pollinate itself and other females present. It will not produce as much pollen as a pure male, thus less seeds. However, these seeds will be 100% female.
CONCLUSION:
Now, femenized seeds have also been known to produce hermaphrodites. This is just an evolutionary safety precaution to ensure the survival of the species in the event of environmental catastrophe. All seeds have the potential to hermie. Variables such as pH levels, lighting scenarios, fertilizer problems, etc. will also be factors in the outcome of the plant's sex. Just keep 'em healthy, and give them your tender, loving care, and you should be fine.
