1,000 W HPS for VEg?

I have two dual spectrum 65's on either side of six plants and one 1,000 w hps that I use above. My question is I am going to try six sativas next and wanted to know if I would have better results with a different lighting set up for the veg stage. Any input would be appreciated. Thanks

I would buy a mh conversion bulb and switch out the bulbs when you change light cycles. That would be your best bet.
