Some strains will develop male flowers at a lower level of stress than others. That's to say, some are pretty tolerant, some will seed up on ya with a few minutes of light during the dark cycle.

You are right to assume a female plant will produce female clones, but there are no guarantees against hermy-ing (lol) unless you take all the precautions to make your plants as healthy and happy as possible. I swear I remember a thread titled "hermies in action"... I think it was here but when I do a search I'm getting nothing. Maybe I'm crazy?

Anyway, just search for hermaphrodite and the effects of stress on cannabis. My advice, read everything about everything, and don't stop even when you think you have everything dialed in. Innovation exists for a reason

Stinky is very keen on keeping her babies happy, maybe she'll chime in at some point. I saw she posted on another thread pointing out a (possible, but looks like it to me too) pollen sack on a female clone (which would be an even bigger bummer than that happening from seed, and a dead give-away you're doing something wrong.)

Take care, jmd, and keep reading, then once theory turns into practice, read some more :smokin:
