will this setup work or will the bulbs cancel each other out orget to hot.I only have room for 1light shade I have a MH 400 and HPS 400 I figured why not use em both at the same time .Am I wasting my time should I just use 1at a time.
There is nothing wrong with mixing bulbs, it's actually a very good idea. I mix HPS, CMH, LED, and Tanning bulbs to get optimal spectrum distribution. That said you usually want to shoot for 60-75% HPS or Warm (<=3500k) and 25-40% 6000k+ or MH. And the opposite for veg, 60-75% MH/6000k+
As long as you can control the heat I wouldnt see it being a problem. Just remember that m.h. runs hotter than h.p.s. so you will need more ventilation than if you were to just runthe h.p.s.
