I currently have a 4x4 tent . I have 2 400w hps/mh dimmable ballasts with reflectors not hoods. My temps stay around 78-82 with lights on. Rh 55 for vegging My question is will it be more benificial to use one mh bulb and one hps bulb or continue using two hps?
 
In a few weeks when its time to flower imma switch it back to two hps. Its been two days since ive changed it and i can tell a huge difference in growth. Im thinking the mixed sprctrum is good for veg whereas everyone knows hps pruduces better flowering. Any more opinions?
 
i've heard you want a 3:1 ratio of mh to hps. yield decreases when using mh but quality supposedly improves. i'm not really sure of anything this is just what i've heard and it sounded right.
 
i like side lighting (HOT5) in the blue spectrum and an hps above
if i were in your situation id do 1 of each, and put red spectrum t5's as side lights
