If I wanna try and sex my plants early then re-veg them, is it imperative that their 12 hours of darkness be uninterrupted? I wanna sex early so that I can free up space for the ladies.
I've done this many times (sexed early). I've never had a problem with it. Also, if I put my clones outdoors too early, they will start showing, but then go back into veg. As far as 12 hrs darkness, different people have different opinions. I would think not too much effect because mine start showing outdoors. They're being exposed to the neighbor's light, the moon, etc.
