Regulars only, growing feminized seeds only contribute to shrinking gene pool of cannabis. Fem seeds are way more likely to herm, from my experience. I think creating fem seeds as a breeder is a great way to protect your work however fem seeds are not as desirable for the experienced growers. Not to say you cant find killer weed in fem seeds and I have even used some in some home pollen chucks projects but now I am really focusing on keeping virility my gene pool, no more fem seeds.
Finally, for those of you that are worried about wasting space and soil, it is such minimal cost, here is how you do it. You put your seedlings in the flower room in 1 gallon pots in some corners (no need for strong lights here, I keep mine 5+ feet away from lights at times) wait until they show sex, you dont have to have them looking great here you are simply waiting to know their sex. When they get close, look daily, as soon as they show sex top them and place them back in the veg room, you can transplant here if you like into much larger pots. voila, now you can veg your plants as long as you want and you know you are not wasting time on a male. every once in a while you get a special male and you can put in by a window in your house for another 10-14 days after it showed sex and you will be harvesting pollen to make your own house strains. AWESOME.
