MH and HPS conversions

[smoknjoe]

So, if I understand this correctly....

They make MH conversion bulbs that can be used with both MH and HPS ballasts.

Is this right? So, if I wanted to use MH during veg and HPS during flowering, I could buy a MH system and an HPS conversion bulb, or I could buy an HPS system and a MH conversion bulb, right?

Is one method cheaper to purchase? Is one method more efficient? Is one method better for the crop?

Thanks for ANY insight on the topic.
