How big is the space.

A 400W convertable ballast that takes both Halide and Sodium is ideal. you can veg and flower with the same ballast and get better results imo than with CFL's and HPS.

Temps are manageable with a 400W.
Ventilation and air circulation in the closet would be another thing to take inot consideration prior to purchasing.
