So have you ever turned a a female seeds into moms?
If a seed will change sex on it's own, It's because it's not fully stable..
Almost every plant in the world is hermie, if it wasn't for use breeders most likely all you would have is hermie marijuana, inbreeding that takes place by naturally growing pot is almost evrytime hermie..
But back on the subject..
A stable strain or clone only strain will almost never go hermie unless if your intentionally trying to cube a male..
I reveg all the time, I have had this arguement a 1000 times on here.. But regardless I know how to make a female into a male... And how to keep a female a female..
once you understand the science of making female seeds you'll change your mind too..
Bottom line I feel they are unstable and Moms are the best idea for keeping female only strains...
I use female seeds all the time. Never seen a hermie. Thats probably more due to stress than anything else. Dont stress your plant, dont get a hermie.
