mvs produce more uv than mh or hps and are a decent suppliment for Hps during budding . The higher UV is the reason for the heat issues with MV. I would never use a mv for vegging or flowering a lone but it is a cheaper source for supplimental light than mh. And I remember reading on OG that mh bulbs will work with a mv ballast but I have no way of verifing that.
