I would rethink that if I were you, my current plants vegged for 28 days and they are 3ft tall including the pots (currently 4 weeks into flower). Flourescent lights have poor light penetration, if you vegged for 4 months, the bottom of the plants would be so far away from the lights they would produce very little.
