I'm a bit confused when you mention percentages. I think I'm missing something here. First of all, are we calling light a ray or a wave? Let me get this straight. Each bulb pulses a length of light in frequencies equal to that of the bulb type? That makes it a ray? The light is three dimentional right? Where is the width and height? If you are give a plant 90% red spectrum, what is the actual amount you are giving it?
