Hey guys, my metal halide bulb by iPower went out. I use this type of bulb for veg growth only and then I switch to HPS during flowering. What I've noticed is that MH bulbs dont last very long compared to HPS, I was wondering what brand makes quality, long lasting MH bulbs, preferably a 600watt. I have seen Advanced Nutrients make a MH bulb, but I'm not too sure which brand is best considering most of their claims aren't certain. What're your guys' opinions?
