Hey everyone, so I have a foreclosure clean-out company and continually collect things for my growing ventures for free. I am pretty spoiled. The other day was the biggest score so far. I opened up a shed in the backyard and low and behold there are (2) high bay 400W Metal Halide fixtures and ballasts. I scooped them up right away. My question now though is how do I go about using these monsters? I will obviously be using them in a larger space than a closet in the near future. I guess I could just rig them up to the ceiling like they were intended but how do I wire these bad boys? Any comments and suggestions are much appreciated...also I will be posting my "Ultimate Frugal Grow Cab" thread soon... PEACE!
