Light arrangement: Vertical multiple 400W CMH - Vertical / Colosseum Growing - International Cannagraphic Magazine Forums

I'm putting together a vertical system inside a 4ft X 8ft X 7ft Sun Hut XXL tent. After all that I have read about CMH lights, I have drunk the Kool Aid, as it were

So, I've decided on coco, drip to waste. Other than that, I'm open to suggestions. I'm totally open on layout and number of plants, as well as number of bulbs. I would like to do bare bulb as long as ambient temperatures allow, I'll transit to cooltubes and AC in the summer.
My questions: One circle X 2 tiers with 2 vertically stacked 400W CMH? 3 tiers?
Colusium? My biggest concern is maximizing the amount of available lumens for my space, for the highest grams per watt. Y'know, efficiency!
BTW, this ain't my first rodeo, just my first vertical AND first CMH grow.
My strains are Satori and hashberry, but I'm open to suggestions on that, too.
Any advice and comment is welcome, with thanks!

you could have one bulb mounted from the floor up and then hang the other bulb directly above so as they're stacked almost. I'd recommend 3 tiers to optimize your grow area and new bulb.
