Looking for opinions/input

I made a frame for my QBs and was wondering if itll be sufficient for what I need. I'm looking to cover a 4x4 area. I made a 3x3 frame with 4 atreum 288.2 boards there is 12" between each board and 18" between the 2 rails. My question is should I throw a couple 2' strips in the middle or should I be good to go?

What driver(s)?

Do you have heat sinks? Do you plan to use more than one driver?

Without heat sink you may be limited to about 60W each board.

An additional one or two boards in the center would be ideal, imho.
Atreum has a nice 34" frame that holds 2-3 288 boards as well.

I don't have heatsinks yet. I plan on throwing a 16" either above it blowing on it or light level

I'd try it about 18" over the floor and see what the light distribution looks like.
