Anybody have a good set of plan for a 120g canopy that can house metal halides along with the magnetic ballasts? Can you lay the ballasts on their sides so the canopy doesn't have to be a foot tall? How much cooling would be needed if the ballast were inside the canopy? BTW they are 150 watt HQI. I would like a completely self contained hood if possible.
