I am now running a 250 watt Hortilux HPS(with an enhanced blue spectrum) 96 watts 6500K T5, and 96 watts 2700K T5. All I need is some supplemental LED lights and I got every part of the spectrum represented.

The blue light during flowering definatly enhances the qaulity of the buds. The buds that are directly under the 6500k bulbs are always frostier.
