    I think for this genus it is overkill. You would have far better results growing your plants outside in the sunny summer, and placing them into their appropriate dormancy in the fall. I use my HID lights in the cold months when good light is hard to come by to maintain a rather extensive collection. If you are growing a limited number of plants, flourescents would work as well, and are FAR less expensive to burn.

    Also, note there is no "cool" metal halide. They generate a great deal of heat, and their employment demands a humidifier or two in the room which run on mineral free water, and potentially could require some sort of exhaust system to remove the excess heat generated by the lamps.
