xcrispi Reviewed by xcrispi on . Mercury Bulbs? Hey i thought i read somewhere that Mercury Vapor bulbs work well. IM not sure what stage either flowering or veggin but i bought a 100W bulb a while back. Could this be used while my plant is just sprouting? And if not, what bulb is best for a 2 week old plant? thanks for any feedback Rating: 5
