I'm building a pc grow box out of a server case that is 24" H x 8" W x 20" D and I am going to use a 70w hps light installed into a home made cool tube. Any electricians out there that can give me some tips on the wiring, like where I should ground the ballast? Or should I have someone with more experience to wire the light for me? ANy help is appreciated, thanks!
Safety first my man! If you haven't wired ballasts before, and have a trustworthy friend who can, by all means let him teach you. Without seeing the ballasts and wiring config, you can't get a definite answer here. What you can try, if you feel somewhat safe about trying, is to attempt to find the ballast model online and most times you can find a schematic. Above all, be careful. Peace-OGH
