Metal halide in flowering

This what I am running at the moment, I use it for the last 3-4 weeks of flower.

Have you noticed an increase in trichomes at all? These bulbs look great but I can't run them because I use magnetic ballasts.

I'am finishing up my first grow and used a 600w mh for veg and flower. Next run i plan on using mh and hps for a full spectrum but i think they turned out pretty good for a noob

I currently run an ultrasun 400w 10,000k Blue enhanced MH for veg and i love it! Although I've never used it for flower i can say it's a great bulb for veg phase. Im not sure you'll find many if any people here flowering with MH but i could be wrong

I don't want to say you're wrong, but you might be surprised.

Halides for bloom are great, especially under certain circumstances. They will tend to keep your plants bushier with more compact growth. A standard HPS will tend to induce more stretch, which is often undesirable if you have limited vertical grow space.

Also, while HPS lamps are ostensibly more efficient than Halides; producing more lumen\watt, less of that light is photo-synthetically active (PAR). I don't know off the top of my head how they fare in terms of PAR vs PAR and it definitely varies by bulb manufacturer, but it's something to keep it mind.

If I'm running more than one lamp in bloom I use both MH and HPS.
