I grew two plants of NL (using LST) earlier this year, I vegged em for 10 weeks and flowered under 200w cfl. I got 3oz from one and 2.5oz from the other. Not bad for CFL - but they did take forever to finish, like 72 days instead of the usual 8 weeks.

As you alluded to already - the amount of time you veg and the lights will be the two most important factors, after that training will help with yield.

NL is a great plant for a first grow, really tough and a decent yield.
