so I want to buy a ballast and bulb separate and build my own grow light. I'm not worried about the electrical aspect of things I know a guy for that. I'm just wondering what specific ballast I need to buy to run a 400w CMH bulb? or a 330w bulb if that turns out to be the best option.
also does anyone have any experience with CMH lighting? any info is appreciated.
