Thanks Zandor,

Let me clarify my situation; I am growing in a closet with a 400W HPS so I depend on the cold winter air from an adjacent window to keep temps at 80 rather than 180, lol. So basically I need to be done with my grow well before march when it starts to warm up (i am aiming for mid-late february. So I need to figure out how much time i can afford to to veg it.

Is 10 weeks a safe amount of time to allocate for flowering? If this is so it would mean that I would probably be switching to 12/12 on Dec. 2nd. Meaning I would have vegged for exactly 42 days (she is 25 days now). Is 42 days a long enough veg to get a good yield?

Thanks for the help,
