I found a 100w MH that I plan on using for mothers/clones at a thrift shop and I'm attempting to wire it up into a remote ballast. I'm just using the housing as my ballast box, and removed the reflector/socket and drilled a few holes to thread the wires through. Basically, I have it all wired up, but now I'm trying to extend the wires that run from ballast to the socket... where to I put the ground wire, or is it not necessary? I grounded the wire from the power cord to the bolt that's holding down the ballast, but I don't see one for the socket. Do I just clip off the ground wire in my 3-wire cable and hook up black and white only?
