I dont recommend to breed hermi, but free beans are free beans and if you have the time to select and kill plants id say keep em for practice and research its what i do.
Also ifyour environment is off then yes you could easily get two herms especially if they are not from really great breeders. Even some of my strains herm if the environment is off! I do however kill and run tests on all the gear we plan to release. th
but anyway whats the background on both strains, what bank autos or photos. let me know i could better answer some other questions. i do know that my nlxbb from wos hermed really easy no matter what was a B$%# to grow. i ended up just murdering them all.
I hope to see you succeed in your grows im subbed.
also When i spot a herm in the med garden or breed garden i slay them immediately.
so for future reference if you have the time and patience to go threw them daily and pick the balls off id just slay em.
also pollen is easily killed by water. so if your worried about putting new plants in the room just get a waterr bottle and spray the room down good.
