You mean your room is 120 sq. ft. ?

Two 600 watt HPS's aint even near enough for an area that size. You're looking at 6-1000 watt HPS's or thereabouts. 1200 total watts means you are only going to have 10 watts per sq.ft.....

Multiply your sq. footage by minimum of 40, I use 50, and that will tell you what you need.

120 sq. ft. * 50 watts per sq. ft. = 6000 watts

Your two 600 watt HPS in combo would be good for around 24 sq. ft. ( 4' x 6' area).

You could divide that room up and make two flower areas of 20 sq. ft. and use 1000 watts in each area. That would give ya some kick ass results.

bongerstonerd00d Reviewed by bongerstonerd00d on . Lighting overkill? 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.
