growing with MH's only?

[Grindbot]

well if i can find an MH bulb that will work with a HPS ballast i would be willing to bet you could find an HPS bulb that works in MH ballasts

but if you cannot, or spending money simply isnt an option im sure you can grow with just MH except your yield will just not be as much as it would be with an HPS during flower

I know its not going to be as yielding as an HPS, but strictly using MH lamps will be better than using strictly CFLs, correct?
