My one flower room that i am setting up is around 120sq foot, the clones/seeds/young plants veg under a 400w MH would 2 600w HPS for 120sq be over kill or just about right on? I thinking right on, but other opinions are welcome, the other flower room (for special purposes) has a 1k HPS and is about 80sq ft and they do fine in there, but again, its only a few that are "specialty" plants.
