Yeah your all right, and definitely answered the question better
5x5 is a much larger space than it sounds, I wasn't thinking of using the entire 5x5 footprint, maybe 4x4 of plants in my head...
I would love to put 4 of em in 5x5 as more light is always better, but the price tag of that would deter me atm
My plan for the next year is 3 in a 4x4 , So i'm jumping along the crazy train soon lol
Good luck with whatever you choose, let us know
