Colateral Silver

i don't have experience with "colateral silver", but i know colloidal silver.. I haven't used it in my own grows, but i assisted someone else years ago, where we had used it.. 30 pps should be good for getting her to produce sacs. we had taken two cuttings of a nice female, put them directly into 12/12 (i don't think we even rooted them, but i don't remember) and a few days later the other guy started using the colloidal silver on one for about two weeks or so, while the second one was left untreated. Once we harvested the pollen, we had to wait a little while longer, so the female was ready (males usually are faster than females). With us it worked quite well, but i'm not sure about the success rate, i mostly helped with the cuttings and harvesting of the pollen.. the colloidal silver procedure was his task, as it was at his house and i only came by every once in a while.. I did plan on trying it in though in case my white widow is not a male.. (yeah, doesn't happen often that you find people that hope their "from seed" is a male ;)) I don't need feminized seeds at this point, as i first want to do a cross pollination..
