M.H. bulbs are white/blue in the spectrum. They are the best lamps available for vegetative growth of indoor plants. This type of light spectrum promotes short, compact growth in plants. They are ideal for indoor greenhouses and commercial growing applications. M.H. bulbs emulate bright summer sunlight. To plants, this means quality simulated sunlight and a high photosynthesis level. These bulbs are universal, meaning they can be burned in any position, vertical or horizontal.
