color looks like an mh but the bulb seems to be a christmas dilldo in other words an HPS, most people vegitate with mh and even flower with it mh gives u less bud but much better qualety tighter fatter buds i think the best thing would be to veg with the mh and then put the HPS on with the mh during flowering ull get the streching effect of the hps and the fettening effect of the mh
peace
