If you're talking about using one 100w equivalent bulb, no way, that's only going to be like 1500 lumens or something. A cfl that uses 100w might be barely enough bc it would be about 5000-6000 lumens.
It is better to look at lumens rather than watts. I have heard you need a minimum of 3000 lumens per sq ft of growing space, but 10,000 lumens is like the sun's output on a summer day. That is why i have almost 15,000 lumens focused on one plant.
But I am obviously not an expert as it's my first real grow attempt.
