The light you use must be the sun in your plant's world dude, have you ever noticed how very bright the sun is?? That being said, plants metabolize nutrients into the sugars and carbs that they need by means of photosynthesis, and that means that they need a very intense and color correct light in order to use the nutrients, water, and CO2. Quality lighting is the key piece of the puzzle. Here try this analogy: if you had a V8 in your car, would you put 2, 4, 6, or 8 spark plugs in it? Well you would put 8 in it or else you would be wasting alot of potential power, right? Well the light is like the spark plug in that it utilizes the rest of the factors in the equation to render the end product, BUDS.

That being said, go to Lowe's and spend $50 and buy a 70w HPS security light and rewire it for your grow room. HPS is sooooo intense it makes you buds grow bigger and the light color is good too.
