Excellent 
600 Watt HPS Grow Lamp
The standard Sodium Lamp generates light in the orange/red spectrum and is perfect for developing flowering plants. When used as part of a two-lamp strategy (with a blue spectrum Metal Halide covering vegetative growth), results are always fantastic! Sodium Lamps can successfully be applied from cutting to harvest but most growers prefer Sunmaster/Grolux Lamps for this approach.
