1,000 watt, MH to veg, HPS to flower, Need switchable ballast to do that. You're going to need allot of other stuff and systems to support that to the tune of about $1K. I'd do some research in the "grow room set up" forum and youtube and ebay searches. You may find all you have done is awaken a sleeping giant.

Why this need to start balls to the wall full blast? (rhetorical)
