And if it breaks? If mine does anytime in 8 years its replaced off the shelf as Rhizome mentioned.

And yes, i'll stand by that statement. It's your word you built it....and your word it's worth as much as something I bought. I think I'll leave this discussion right there....have a good day.
Weedhound Reviewed by Weedhound on . Building a HPS is cheaper? I was going to buy a 400 watt HPS light from a hydro online store when I had an idea. I looked into just buying the components of the HPS ballast and then the bulb. I found a site that sells them but I was wondering if this is all I need for a functional 400 watt HPS system? I think I may have to add a cord and socket to the ballast but it's alot cheaper in the long run. Is this all I need? Ballast (needs cord) Rating: 5
