    What I do is start my seeds/clones under T5s then move them onto a cfl then onto mh, for the 1st 2/3 weeks of 12/12 I keep the mh in (until after the stretch) I then change to a dual spectrum (Sylvania Grolux)
    By using the mh for the first 2/3 weeks it helps stem the stretch.

    Imo a Grolux hps dual spec and an osram vialox son-T hps are much the same.
