what kind of light do I have here? It has 150 watts but I cant find what type of light it is. I know, major noobie. Also, I have a 5x2x2.5 grow box. what is the max amount of plants I can have with this light and grow box size. I grew once before with this equipment with an old roommate so I know a bit about taking care of my ladies but as far as equipment goes, Im a toad.
