Is it still considered to be the best policy to veg with MH and then switch to HPS for flowering? Has anybody tried variations on this?

HPS for everything thats how the dutch do it so why change

However, yes you can add CFLs to get better light coverage....

You can use either HPS or MH all the way from veg to harvest, probably better off going HPS all the way thru. I change from MH to HPS and also have a dual ballast so all I need to change is the bulb. It's not required but yea it's done all the time.
