Dont buy anything US if your in Europe, search for Euro based companys with the ballast u need, also, get a hig pressure sodium ballast you can run a Metal Halide of the same wattage in a HPS ballast. Read some grow guides and brush up alot there is no sence is buying all that and not knowing what to do and your crop dies. i spent a month watching videos reading posts reading grow guides, i even read a book about the botany of cannabis.
