MH&HPS vs HPS entire grow

What i want to know is it worth running a MH for veg and HPS for flower or just HPS for the entire grow?is there any noticeable difference between a plant that was vegged under MH? ie plant health, node length,bud sites,bushyness,height?pics appreciated

using both will give you both endsof the spectrum so you will yield more. if you have both use them if you cant afford both just get the HPS but both for better results mannn
