Guarantee your crop with feminised seeds.
Instability of gender is a desirable trait in the wild when it comes to breeding, but only female cannabis plants contain psychotropic material; high concentrations of THC and CBD.
Through a combination of cloning and "shocking" plants, breeders/seed banks can get them to produce feminized seeds that reliably produce female offspring.
A clone retains the same sex throughout its life, so the clone of a female plant is also female.
Feminized marijuana seeds take the risk out of growing by producing female, bud bearing plants, time after time.
