10x10x7. Is 2000 true watts enough ?

4 lights works in a 10x10 cross lighting for adjacent fixtures makes up some of the edge intensity losses.

Either way 2000W isn't enough to flower that room properly.

could be OK if he isn't using all the floor space and has walkways around the edges or something.

That's your biggest problem I think. If you pinched/topped those plants after 4-8 nodes then you'd have a wide bush not a tall stick. The wide bush x the hieght obtained during stretch is what equalls large yeilds. W/ your Grow style needing a dialing in to do this w/ 7' ceilings, you'll definitely need/want strips or bars. 900w over x8 commercially desighned bars (large, finned, glass, detachable, pivoting, modular sets) @ 2.78 umols/j,w/ an enhanced white spectrum, ballanced accordingly, my 900w Bar light evenly covers a 7.5' x 4.5/5' area @ an easy 900+ ppfd around 18-22". With that said, you technically only need two of them. Centered in a 10' room, there's only 1' on either end for a Lil space that won't be there long. The plants will outgrow the 8' space & take up the 1 remaining foot on each side. Spill-over. The Bars Pivot too so the 1' on each side that is well luminated anyways, can have a bar pivoting that way too. This is your least expensive route & you can easy harvest 10#'s on a regular. The two power supplies are recommended to be outside the room for a 30% reduction in HVAC. Each plant can easy be a 4x4' x 3' tall colas. Bar lights claiming 640-720w a 4x4 are compensating for the human/lumen, wh/+red spectrums & also Over-Saturate if following recommendations by the manufacturer. Most manufacturers (pass on false info.) Are providing improper recommended instructions. I scabbed this pic from a previous member here who has the same light as mine. This shows an 8'x5' even coverage situation. 1800w makes x2, done! Apologies I vant show my own room as it's being re-hauled. Goodluck, just use your head. What's recommended by manufacturers and their followers are not always the way to go.20210414_212258.jpg20210427_215123.jpg20181125_184243.jpgimage(1056).jpg20220426_224554.jpg

I think your going to come up short on wattage, just my opinion. 600w in a 4x4 is 37.5w and was powerful enough, like the 660w I'm using now. Tie those plants down, abuse them and they will surprise you. Kushman choiripracticy, topping and lst. All very good techniques. Id buy bar lights with largest footprint, easiest to cool.imo. And why autos? You can control photos easier.

No.. you want 35-45 watts per sq ft for bloom.. you have a 10 x 10..so 100 sq ft ..

Yes, I'd agree if we were still In the early COB error. And maybe your right based on the white or wh/+red spd's being used. But one thing for sure is not all Led Grow lights are made equally. A high Luminous spectrum will prob require 35-45w/sq' to hang. But thats not going to increase the quality, just equal out the yeilds. At 26.9w/sq' , I'm maxed out as for results I feel. Sure, one could cram multiple plants in n do a Lil better but w/ 2 plants in 7's under 7.5'x4.5' of enhanced white Horticultural bars I get a steady 5#'s & do not have to reduce myself to 6-12" canopy distance to achieve it. 8' length Is easily obtained with the pivoting bars & fully modular design. Lab reports blow away the standard wh/+red & you yeild about 30% more just spectrum & design related.
