that seems like the best way to go about it. Is it very simple to do? I never really looked into it.
Yes it's easy.
Grow regular seeds
Put into flower when ready
Identify male and female plants
Pollinate female plants with males
Grow female plants until seeds are mature
Harvest plants
Separate seeds
Smoke deseeded buds or use for concentrates
You might not have the latest tuity fruity pinapple haze kush purple paddywacker strain but you don't need all that. And you'll have all the seeds you need without spending $10 for one seed which is just ridiculous.
