I dont really know what the advantages are. i dont need anything too fancy... i just want enough light to grow about a half pound of dank buds every 3-4 months.

Is a digital ballast more energy efficient or something? Im kind of new to this.

I also thought about inline fans, but i dont think they will be enough to push air through my future carbon filter.
