dark period

Do u need a dark period b4 flower if so how long

From my understanding the dark period helps initiate flowering quicker (but this is negligible)... really no reason to do it.

You only need a 12 hour dark period.

Yeah. I started 12/12 after about 10 days of veg. By 3 weeks old it was starting to flower.

Some people put their plant in total darkness for 24-48 hours before 12/12. I think that is what the op was referring to. Either way, like I said. no reason to. I put my girls in to my 12/12 tent right after the 12/12 tent goes dark. Working fine for me.
