100 watt equivalent or actual 100 watt draw? If it is the latter, it is good for about 3.5 square feet. If it is the former, It's good for about .75 square feet or 9"x9". There are many different ways to grow to maximize your area and light type. Check out 420Fiends 2lt bottle grows for a good example. Either way 3 plants will be pushing it.
