Has anybody seen a multi wattage ballast before as i have managed to acuire one and i have been around loads of hydroponic grow shops and they have never herd of one. It takes 250, 400,600 & 1000watt H.P.S & M.H bulbs. If any body ownes one or has ever owned one can you let me know how you got on with it & maybe how much it cost you cheers TOMBONG.
