General consensus seems to be 70-80 days, my experience as well. Only difference I would add, I'm hydro and my girls usually show around day 10.
Now... one thing I do a bit differently... I germinate my seeds by an overnight soak, followed by dropping them into a rapid rooter plug and placing them in a Folgers coffee can bubble cloner. I leave them in a warm dark area until they germinate (usually 3 -7 days) then put them under a 42W daylight CFL. When I'm on point & not lazy, they reach three nodes in a week to 10 days, but I've gone as long as 3 weeks / five-six nodes before transplanting. I never count this early veg time, and it never seems to change the rated finishing time. But the increased root mass from the early post-germination period seems to have a very positive effect when I transplant to HID or LED.
