Need help with auto flower breeding!!

Hi guys thanks in advance for any advice!

I want to breed/produce some auto flower feminised seeds.

Am I right in thinking I can spray 50ppm colloidal silver on my choice of feminised auto flower strain (once it's started flowering) and produce female pollen then pollinate another feminised plant and produce pure feminised auto flower seeds?

Sorry if that's confusing this will be my first attempt at this!

Thanks

You may wanna re ask this in the breeding section for a better response. I have never bred autos but have with photos. I would think that unless the female you are pollinating was an auto aswell you would only have about 50% of the seeds be autos.

Ok that's great thanks for your reply
