  1. My personal preference is to buy a bulb and ballast design for growing. So, neigh...
  2. Do I really need a Ballast?
  3. Yes. But before spending any money spend 2-3 weeks reading. Knowledge will save you couple of hundred dollars....

  4. Yeah youll need a ballast but I know i poped open two HPS floods to make into cooltubes and the ballasts were advance brand, and they sell advance brand ballasts loose in my Sunlight supply catalogue for growing plants, and have always heard that advance and universal ate the tip top names for loose ballasts or replacement ballasts... the only difference is the reflector design, that might actually be more suited for growing coming from a grow company, All ballasts follow the same ANSI standards. Bulbs do make all the difference.
