How to make a female seeds

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!

I'd proibly wate till they are about 2 to 3 months old , have your plants on a 24/0 system so that they will grow faster

what's the point? just seed it with pollen and get stable genetics. what you are suggesting is not a good thing.

agreed, thoughtfull but not a good thing to recomend. most hydro stores sell a chemical solution that promotes hormones in female plants to produce pollen. you fertilize your budding females with female pollen thus producing female seeds. this all should be done in a compeatly seprate grow house since the pollen is still potent and can result with infesting a beautifull crop full of seeds. (still sux even if the seeds are feminized)

I know the chemical ur talking about. what is it.... Gibbileberic Acid or something like that. Ive never seen hydro stores sell it though. But fdd is right as always. u will end up with hermie seeds if u just turned a female hermie.

i like to find females that WON'T hermy even with light poisening...
sign of a strong girl =]

gibberrillic acid, colloidial silver, and long flowering times are the most legit ways to make fem seeds from what i understand...
