I agree with others here--it's not enough. You've got around 10000 lumens total, which will be fine to veg plants. But that's enough light for about 2 sq. ft., which is enough to take two small plants all the way through flower.

If closet size is an issue, I'd consider going with a 250w HPS. You can grow 4 plants with that--not monster plants, but decent 29-36" plants that take up around 15" x 15" each.
