I actually got the Super HPS instead of the Blue because the manager of the hydro store told my that I could run the blue start to finish but the HPS is a better choice for all around growth because of its enhanced blue spectrum. And it was like $20 less than the Blue MH so I figured he wasn't bullshitting me. So I pulled the trigger on the Eye Hortilux 400 watt Super HPS. Seems to get nothing but good reviews, so I figured I would give it a try. I usually run the cheap ass bulbs and just get new ones for every run because they are like $20-$25 but after thinking about it I figured if the hype is true I may get a better crop so we will see.
