Only 2 lights for 10-12plants??i'd say run 2 lights in the room and run an extension cord for 2 more lights from a different room. if you want 3000+ watts you might need an electrician if you don't already have 30 amp breakers on your rooms.
Ohhh didn't read that 2nd part properly bout getn 2 more lights running off extension cords from another room...Only 2 lights for 10-12plants??
U talking 600watt HPS lights right? How bout running 4x600 watt with 4 big hood shades,would that work???
Also u think I won't have to jump the power if I run under 3000 watts?
