argomax 600 hps grow what would be better

600 watt argomax hps.... if it is better to veg with it or use my 250watt (65000k)mh. dont have room for both. argromax says 30% more blue, would that be equal to 200watt mh(6500k) and 600watts in 2200k hps

its going to blow a 250 watt MH out of the water if thats what you wanted to know. Personally I Veg AND Flower with HPS, yields are nearly the same.
