What to do? 150W HPS for Veg?

I know it will work. But my question is would it be a good investment to purchase a MH?

I need to veg 2 to 3 moms and possibly clones under this light. Would it be a good investment to purchase a 250W MH or 400W MH? Will it make THAT much of a difference?

I have a 600W HPS for flower..

Any help is appreciated

i would say a 400w mh would be great for that setup, its less intense than the 600w so it will transfir perfectly, if you got a lower one it might shock them a bit more than the 400-600.

and with the 400 you can do clones as long as they are as far away from the light as possable. or at least in the shade of the moms.
