ok I'm planning on putting 4-150w HQI's and 2-160w VHO actinic over my 125g. does any one know of any ballast that will run two of the 150w HQI's so I dont have to buy 4 ballast's at $75 each. if I make the lights ordering from hellolights.com it will cost about $700.00 all said and done then the cost of the DIY canopy. I dont want to spend that much, I think I can do it for less if some one knows how feel free to let me know
