I would really suggest that you use the flous only for cuttings/seedlings and with 10 plants depending on how well you have them spaced out will depend on the light size you need. You can cram them all into a close space and do the sea of green thing, but a 400w HPS can cover up to a 3X3 area. You want at least 45 watts per sq. ft. A 400 will give you 44 in a 3X3 area which is ok. Here are the demisions that lights can cover: 400W 3x3 max 5x5 600W 3x3 max 6x6 1000W 4x4 max 7x7. You need to check online for a light or if you tell me you area i can tell you or a hydro store near that will have everything you need.
