Re: LED & CFL questions
Led is okay for veg, just keep it far enough from top of plants.
140w should be enough for 2x2, but you could add some 2700k (for flowering) cfls if using 2.5x2.5 tent.
You can always add cfls to have better covered lower parts of your flowers or corners of your tent...
I am pretty new to this, but i'd say about 2-3 weeks, depends on amber percentage you are looking for and the strain :)
