No, its not enough. You barely have 200W that is definitly not enough if you are planning to fill a 10x11 room, it prob wouldnt be enough for even a 5x6 room. It really depends on how many plants you are going to have in your space, if you are going have over 5x6' of plants then i would say you would need at least 400-600W HPS, anymore than that, especially up to 10x11 i would say get several 400-600W HPS, or possible a couple 1000W HPS. But you will be very dissapointed if you try to grow more than 4 plants with the 200W you have.
