answer to title: whenever you are 9 weeks away from wanting to smoke weed.

12 hours of un interupted darkness is what does it. Are the plants from seed or clone?

I would make a clone from mamma after roots flower right away.this will tell you what you have.You should be able to tell 7 days after 12/12.Experienced folks can tell after about 4 days.
