Depends, I make seeds regs and fems, lots of breaders out there say we are destroying our favorite plant by feminizing it. The fear is it will cause more and more hermies, with the end result being a self pollinating plant. We dont want that! BTW I never get 50% males, last year I got 0 males this year I got 2 from 12 seed. Now I have had it the other way as well, some purchased seed I got 5 males from 5 seed (they were replaced). A commercial grow next to me got 1000 males from 1000 seed (white widow). Some of what I grow is Land Races, if you feminize it it is no longer a land race.
