Oh and as far as how long you need to go till harvest...you stiill got a ways to go before you get to really enjoy the potential of your plant.
IMO, the whole flowering stage can complete as early as 9 weeks (based on strain)...what I do is wait till you see the pistils (white hairs) start chainging color (about 50% from the top...this usually means that the trichs are about to really cloud up)...once they are cloudy, you'll probably have about two weeks from that point (get ready to start flushing because if you time it right, you'll have about 2-3 waterings left)...with a pocket scope from Radio Shack, keep an eye on the trichs...you'll soon see them converting to an amber color (dont try to convince yourself that you see amber if you dont...THEY WILL STAND OUT)...once you see about 10% amber, cut the lights off and keep them in the dark for about 48 hrs (some do less, some do more, some dont do this part at all...but I believe that it helps increase any further thrich development before harvest and really brings out the sweet aroma)...then harvest and start your drying (1-2 weeks)...curing (2 wks - 1 month). Hope that helps out...
