Creating an autoflower

Hello all, i would like to create a new autoflower strain. I have two healthy poison dwarf males that i will be using. From what i understand i need to pollinate a regular female plant with the auto male. Then take a female offspring from them and pollinate it with the same auto male. Take a a female from them and do this over and over for around 7 generations. What should the light schedule be? Also should i give the seeding females equal amount of veg, micro and flower nutes? Should i pollinate the females about 3-4 weeks into flower? Any information will be greatly appreciated.

Form my understanding to create a true new autoflower. You would need a Cannabis Ruderalis male/female and cross it with either a Sativa or Indica male/female.
