Forcing a plant to hermie is not a good thing, as the offspring will more likely become hermies
What you want to do is change the sex of the female plant using colloidal silver or STS

Two things I think are often confusing to understand are:
1. People often say "Making a plant hermie to then use its pollen makes the babies hermie." The babies would likely hermie even if you had used CS on that plant. The thing is that not every plant (not the stable ones) will hermie under moderate stress, but almost all (barring an anomaly) will "flip" with CS treatment. Therefore, you shouldn't ever intentionally choose a plant that was easy to force to hermie, because it already has the low stress tolerance genes (this is where the quote comes from). It doesn't gain them upon the growth of stress induced pollen sacs. What SHOULD be done, for breeding stable strains, is stress testing BEFORE the application of CS. You stress the babies, and any that hermie get removed. The others are good to use cs on.
2. The sex of the plant sprayed with CS doesn't technically change. Sex is determined by the X and Y chromosomes. A female has XX and a male has XY. The female sex cell contains and X chromosome, and the male sex cell contains EITHER X or Y.
When you use CS on a plant, it inhibits the hormone Ethylene, which is used by plants during flowering, to "choose/decide/know" to make calyxes and pistils (female flowers). When you this happens, pollen sacs form like they do on male plants, BUT they are still technically "female" pollen sacs. All of the pollen (which is usually the male sex cell) contains X chromosomes. When used to pollinate another female flower (guaranteed X), you end up with XX (female) offspring, no different than females produced in male x female pollination. Seeds are best described simply as "female", and not "feminized" which implies something was done to the seed to change it to female (when it already was one).

Question have a lot of auto seeds strain could I use pollen from any one strain. auto sprayed with colloidal silver and apply to any strain will that be OK or do I have to do each auto plant strain to go with the other... meaning auto og kush and pollen from og kush....thanks
so if I pollinate one of my strains I could use the same pollen on my other different auto strains....
