i just got 2 70w HPS' from some home depot flood lights and i was wondering if this would be enough for 5 little LR2's? i had 3 but i dropped one and it broke. i do have the ballasts they come with so i know im good on the ballast part. also, i found 100w metal halide's at home depot...how many would i need for about 4 to 5 plants?
