Auto Purple outdoor grow...seed crop

I am growing 2 auto purple plants from Pyramid seeds. My intention is to let one go to maturity for smoke, and to make the other one produce lots of feminized seeds for my future exploits. I plan to use the colloidal silver method of forcing male flowers.

Has anyone ever tried this with an auto strain?

Any tips would be greatly appreciated.

How your grow turn out with the purple auto.

It is ongoing. I lost one of the two, so I have had to order more seeds. I am still letting one grow un-pollinated and it is now two feet tall and has started to flower. It looks like it will make 12 buds plus the cola. I will post smoke report and dry weight in about one month.
