I use to. 600w MH. Got the best growth rates of any light I’ve tried especially in veg.

Buds were respectably dense, not LED dense but good.

Got just over a lb from 4 autos under that light.

Ive heard that blue light spectrum helps terpene production. Always smelt amazing under the MH in flower

The weed I grew under the old 400w ceramic metal halide bulbs by Philips was so much better than the LED stuff I grow now. But you can't beat LED efficiency when it comes to yields.

what about comparing mh vs hps quality/yeild ?

Absolutely! The next run I did with a gavita 1700e pro yielded 23ozs from 4 autos. First time having bud rot indoors as the buds were almost unnaturally dense?

Since I only grow for myself I’ve decided quality is better than quantity. And my LED decided to to break after 2 months of use lol

Also why I like the simplicity of HID lamps. Less to go wrong

Trying a DE 630w full spectrum CMH at the moment. Seems promising so far!

Wow gavita 1700 bar light. That's an expensive light to take a crap after 2 months! I'd be pissed and looking for a replacement or my money back!

Too right man. Was pissed off. Turns out the light was just too intense for my headroom and ability to heat the tent. I extract out the room and anything below 25-26c I started getting bad cal defs.

I swear you could hammer a nail in with some of the buds they were that dense lol

Now its a gavita 850

Jokes aside sorry for your loss.

It blew out weeks before the plants were finished and was run at 75% power from the on. So makes the end weight even more impressive considering it was achieved with about 350w of draw power

Why would it being an autoflower have any effect when using a metal halide vs a photoperiod? It will respond to the spectrum just like any other plant would.

I swear some people think autoflowers are some strange mythical creature with some of the questions they ask.
