swapping out HPS 400w for MH while flowering..

[deftdrummer]

I personally have found that using both MH and HPS through all stages enhances growth positively in a number of ways..

I guess that's the consensus then. What I was trying to determine was if the buds could get more compact as a result of using the MH bulb I started with (through veg). I guess just running both at the same time is the only real way to go.
