If you only have two cfl's, I would myself prefer to get two more for the first 3 - 4 weeks... then I might jack the HPS in.. You can't get a 1000w HPS close enough, you would only burn your plants.. wait one or two weeks, then jack it in!

Also you should use the, uhm, hand method to know how close it should get!
