Bulb choice?

Currently running a small scrog (60x60) with a 400w Sunmaster dual spectrum bulb.

Worth the investment to change over to specific spectrum bulbs for veg and flower - would I get a noticeable difference?

Recommended 400w E40 bulb?

It is definately worth the investment. The bulbs only last a couple of seasons so why not max out their potential?

400's are cheap, I replace after every grow. New mh for veg, New hps for flower. With my 1000 watt usually every 2 grows. I don't see the point in buying the more expensive bulbs, they do say longer life for the price but when I get up to the counter spending money I don't have I just can't talk myself into the more expensive bulbs.

Genesis. Good bulbs.
