growing with MH's only?

[Dutch Pimp]

I have an interchangable 400 watt. When you induce flowering, could you run a MH for week 1 then switch to HPS for week 2 then keep alternating until harvest? Would this be beneficial in any way or do you just stick with HPS for flower.

Thoughts

Thanks

I have read where many, very experienced growers discussed this:

half of them said it was a good idea...the other half, said it was a waste of time....go figure....
