Best use of my space?

I have a small closet to grow in, maybe 4'x1.5'x7'. Light is not a problem and neither is heat. Growing from seed, what is the best use of this space? Should I try and go 12/12 from seed and form single cola plants packed together? Or maybe grow 3 taller plants? Or a maybe some combination?
Growing in soil by the way.

Thoughts?

Thanks

You may look into Autoflowering strains. 12/12 is a good option. I would personally veg for 2 weeks, then right to 12/12.

Good luck!

I was looking for input on quantity and style of growing more so than lighting schedules, thanks though!

Try v scrog head it does good in realy tight spaces but new hear lsten to some off thes other guys first
