I know when to use each one, its just that recently ive been lead to believe Mh arent even necessary and you can just use sodium bulbs for vegging? is this true?
 
yes you can use sodium but they have a tendancy to make plants stretch due to the colour temp.


you could look at the sunmaster dual spectrum lamps that have a mix of blue and red spectrum

what im experimenting with is using blue spectrum CFL bulbs with a 600 watt hps while growing. hopefully with the mix spectrum will help me maintain a non stretchy plant.
