This is not a bad idea at all if that is what works for you, it will certainly be effective. If you are using a grow box you should look into the side mounted T5 cfl's (long skinny ones). They work great too I've heard.Im considering using some cfl's for side lighting, is it alrite to just put them in a desk lamp with the bendable "neck" to point it where I want to, or are there better options??
