Does anyone know if a 150W 20,000k marine metal hailide is any good for a small vegitative grow closet or is the color temp too high as i have noticed most agricultural metal halides burn at between 4000k and 7000k, but the info that i have red on aquarium websites say that the 20,000K lamps are the bluest lamps available does this mean that i should be a better choice then a 6500K lamp?
