Hey Dog,
Thanks for the earlier compliment, I'm flattered but Rusty is in a league of his own. I have been here only a short time, and have not contributed nearly as much as Rusty has to these boards.
Ain't it a real bitch when you want to get a plant to turn and it won't. Mean while some will herm if you give them a nasty look. The colloidal silver method is used especially with the auto flowers because it is suppose to very quick acting and I thought would work with most strains. I have not tried to use it tho, I usually have success with screwing with the dark period. When I was using my greenhouse, where I could not easily do light poisining, I'd use large doses of aspirin to chemically poisin selected plants. It works pretty reliably.
