newbee lighting question

im going to start 3 different bubbleponics systems in a 8x5 shed. i was thinking of putting dual spectrum cfl on each system then 2 seperate 250w hps in between the systems. is this a good way to start? i will have to block the shed off so i dont waste lights but will have the room to grow if needed. any pointeres or answers will be helpfull.
