I am going to begin growing soon, however i was wondering if i have a correct bulb to do it with. I'm going to be growing about -5-10 plants in about a 4x4 area. I just bought a 200watt crystal clear GE bulb that puts out 3,980 lumens. Will this be sufficient? Is it the correct type of spectrum that the plants need? the Box doesn't say what type of it is (metal halide, high pressure sodium etc) thanks for your advice.
