Thanks. I've often envisioned a similar box 3x16 feet on my flat roof.
I'd be concerned about airflow through those outer channels. Suppose you offset the holes to the 1/4 and 3/4 points. Essentially, split the difference on the outer fences instead of the central one.
I'm not sure how to equalize the flow (If it's really needed) otherwise.
