When should I harvest and what strain is this?

This is my first grow ever. Planted a bunch of seeds from a freind and I don't know what strain it is. Can anyone help?
Also, any recommendations on when these will be ready for harvest, and information on how much each plant will yeild would be awesome.
These are outdoors in Manitoba, 3-4 feet tall and these pics are from Aug 21, 2010. Will they be ready to harvest 3rd week of Sept, or 1st week of October?

u wont need to harvest that until the end of october its a sativa dominant so it will take longer to flower..

Which strain??? Its kinda like a newborn baby dropped off at a Hospital, Fire House, Orphanage, Church etc... You might be able to make a few guesses based on skin color, hair color, and facial features.... but that doesn't tell you exactly who the parents are. Looks like a Sativa dominant with white hairs.

Get you a scope or a maginfing glass and when the tricromes are more than 50/60% amber colored cut that ho! More Amber = stoned couch lock body high more cloudy/clear tricromes = more of a head high. Hope this helps!
