What would we add, well that's a difficult question because everybody has different bottlenecks. If you are in USA it's easy mode with 4ft strips, heatsinks and two HLG-480 drivers so that's what I would do.

What quality of LEDs are you using?
900 / 25 = 36 square feet of canopy space, which is about what's needed with the correct spectrum and top of the line LEDs. 900 / 35 = 25 square feet of canopy space, about right for lower quality and older types of LEDs.

Using the Vero29’s with HLG boards.
50 square x 25= 1,250
Probably use about 80% of the space, but if I dim them to 80% the figures are the same.
Need about 200 watts. Probably eventually do 400 dimmed for more coverage.
Looking at some none HLG boards. Twice the number of LM301b Samsung’s at around the same price. Any opinions?

You're not just looking at any board there. You are looking at Atreum whose efficacy is higher than HLG, at least with the ARA-20/40. Their boards will definitely be up there. Yes I would say Atreum is doing even better than HLG so they are a top choice.

You're in a 5x10? (edit: **facepalm** I gotta have my caffeine before reading, lol)
Will be Saturday. Currently using a 5 x 5.
Thanks.
Their claimed PPFD value is a good bit higher.
Ordered 3 @120watts.
Only 1 had a heat sink included. Now those are on the list along with a driver.
I bought the three boards Amazon had.
Found a 4th one on EBay for $20 cheaper...
Compared to my HLG QB they look close in quality. HLG maybe taking the edge. Close enough not to matter.
Physically the newer Samsung diodes are half the size of the old. HLG is currently using the newer chip as well.
Square board. 9” x 9”.
Same number of diodes as HLG.
Atreum heatsink fins are half as high, probably twice as many as HLG’s. I think HLG wins out, but overall I think Atreum’s are good enough.
I haven’t hooked them up. Don’t have a meter. Using the same Mean Well drivers. Same diodes as HLG. They should work for a few bucks less.
