Question about seed

Hey guys

I've just started growing a Blue OG plant from a feminised seed.
What would be the best way to get some seeds from this plant?

I got an assorted pack of seeds and this is the only Blue OG. I want to be able to have more seeds of this strain for later use.

Any help appreciated, thanks.

you have to get a male plant and sprinkle it's pollen on the female.

if you get a female you can use a chem to herm it and self pollinate i dont have the name of the chem im sure some one else with knowledge in this category can chime in

Just clone her. Or by more seeds.

Clone it, then use colloidal silver to turn one of the clones.
Use that to seed other clones.
