I have used a Colloidal silver (40ppm) many times to create fem seeds. I bought this on the jungle website for cheap. Works just fine.
My experience is to spray the week before flipping to flower. I also spray one or two branches only. Marked with a white string. Usually by the 2nd week of flower a considerable amount of pollen sacs are available. You can then collect and save or just shake it around the room.
