How it works

The silver ions in Colloidal Silver inhibit the ethylene production needed by the plant to produce female flowers. In turn forcing a female plant to instead produce male pollen sacs. Because female plants have no male chromosomes, the pollen produced inside these sacs is feminized. This feminized pollen can then be used to pollinate a second female plant which will in turn only be able to produce feminized female seeds.
