that a metal halide bulb will work in a hps ballast,if or when you want to switch bulbs,just disconnect the "x3" wire from the ignitor,put a wire nut or tape around it,and replace with the mh bulb,and reconnect to use the hps bulb,of course the the bulbs must be of the same wattage....bonbon
bonbon Reviewed by bonbon on . lighting and other questions Hey, What types of lighting should I use on my plant? I just planted it 2 days ago...it is outside until I can buy a lamp from Home Depot. what type of lamp should I buy and what type of bulb (watt, etc) should I get? How tall is my plant going to get? It is a white Russian plant. How long will it take from the time I plant it until it is ready to be cut and dried? How often should I water? Rating: 5
