I have had limited experience with fem seeds but what I got was some great genetics. I got Seedsman WW and outside of being difficult to pop, they were awesome. As a matter of fact, I am growing some clones from the fem seeds I got from Seedsman. Absolutely beautiful and literally dripping with resin!
I got 5 fems...popped 2 and chose the best to make my clones. Out of those 2 seeds, I have got 16 plants so far. Pretty good investment if you ask me.
Fem seeds have their place. I would not want all my genetics being fem seeds but it is nice to add some new female stock to the "bloodlines".
