Hermie is an incorrect description, silver colloidal forces a female to show male genitalia and only on the parts of the plant you spray.. this will not produce your plant entirely to a hermie, nor can you smoke the plant you do spray(it becomes toxic). Spray the part of your plant that you want to collect pollen from the start of pre-flower on until you get enough nuts and pollen you want. It will take between 5-14 days to see any sacks form. Collect them, crack them in a ziplock, either by force or allow them to dry, take the pollen and put it in a dark place, (the cooler the better) (film canisters are best) and apply to the flowers with a paint brush. This will be female pollen to female flowers making feminized seeds. Another trick is to only spray one or two branches, wait till they start to nut, cut them off, put them in water, and allow them to form nuts away from your plants. Keep them under a florescent or something else that can be away from your grow. Make sure your silver is at least 30 ppm pure, and you spray twice daily if below 60 ppm and once daily for higher ppm. That's it.
