I researched this and I have some questions before my decision. My grow 'room' essentially has one fixture and that is for the avrg. bulb. I thought about fluorecents because they are cheap, but you have to secure them close the plant and raise them through its growth. In that case does anyone know of any 'plug in' fluorescents that could go into a basic plug socket. With the HPS sodium I run into the problem of will it fit into the fixture and will it guzzle the shit out of the power based on a 12/12 day?
