Vertical closet scrog cmh, hps? need advice

I'm in the beginning stages of setting up a sealed vertical closet grow. I'm going back and forth on plant site numbers, lights, spacing, etc... at first I was thinking about 4 levels with 15 plants per level at 2 foot elevation intervals giving a total of 60 plants. I would also use 4x Philips cmh bulbs bare back hanging vertically but I want really dense nugs, so this may not be enough light, should I double these up and run 8x cmh bulbs?

Now the more I talk with other various friends the more I'm thinking about running 3 elevation intervals spaced at 2 ft 8 in high. This will give me 15 plants per level and 3 levels high for 45 plant sites total. Ive.also been toying with the idea of running 3x Maxpar 1000 SE-DE bulbs.

I'm trying to maximize yield for my given space. I've attached a pic let me know what you guys would do ideally with this space.

Research vertical gardens for all sorts of info. Can be very productive if done right.

Good luck.

2ft 8in for each section really isn't very much room for the plants to grow vertically especially since yours going to have lights above them. How big is the space that you're wanting to grow in?
