To reveg, you want to make sure it is getting a nice dose of N and 24 hour light. I really try to reveg only if I have an outstanding phenol (and I do mean outstanding) and for one reason or another don't have clones. I do know however, that if it doesn't take, there will be another something that is outstanding right around the corner. There is no shortage of truly outstanding strains out there now.
However, since you have some quality known genetics, I believe that I would concentrate on getting those going. Revegging takes forever, sometimes doesn't work, and is going to take up valuable space and light that could be devoted to your new grow. There is an advantage to knowing the characteristics of the plant you are growing also.
If you are serious about this hobby, you are going to want to upgrade your lighting. While these babies are vegging, save your pennies for a HPS or a GOOD LED. Lumen for lumen, you will use less electricity and get lots more bud.
