@NyBushDr, IMO the Atreum Hydra-3200 is the max one can run w/out CO2 in a 2x4. The algorithmic spacing does provide an excellent PAR map as you've indicated.
It causes the plants to grow in a radial array - | /. Actually opens up more light surface! (The QR code Below goes to my IG showing this 'spread.')
Would I buy another? Certainly. I was running a Mars Hydro 3200 Bar Light. The Atreum array physically just fits inside the tent. After two grows, I'm no longer hitting my head against it. A MAJOR Benefit is because it's an array - plants that grow into the lights receive significantly less light than a single Bar light.
It's more than worth the Made in America Tax that makes it ~10 - 15% more than the Chinese fixtures. Cheers!
