I use a 1000 agrosun red sodium on a six foot mover...and ive been messing with a Xtra-SUN MONDO reflector. with hortilux eye 400w blue halide..this reflector is killer for supp lighting..its huge.. the spectrum of the horti is full balenced and most like the natural sunlight....i tilt the mondo reflect at a 45 with the horti blue and drop it low shining it slightly over the top my smaller adolescents and through the lower canopy of the bigger girls on a three part perpetual situation all in the flower room....pound plus every two weeks..love the hortilux..wanta try the super hps horti when i change the agrosun in a few weeks ...good ass lamps, and the mix of lamps makes em nice and sticky fat and stinky...im stoked
