I would do some lst, but 240 watts is a little low wattage for a sog.

Pretty much perfect for a 2x4 full coverage.
I had a 70x25cm 240w light in 2x4 and the hotspot at 18" was 950umol/s and around 200umol/s in the corners. Enough light, not enough footprint.

Go big, you can always turn them down, you can not however turn them up if the power isn't there..
They lie when they say size dont matter.

As many as you can afford. If you are gonna be a serious grower pick-up something from the HLG BF/CM sale if they'll still honor the prices. A 650 or up would be nice.

That's insane dude. 81 watts per sq ft? Seriously,
?Sunkist penetration. Those three plants will be hugeThat's insane dude. 81 watts per sq ft? Seriously,
The other poster mentioned the larger lights can be dialed down. And nobody ever says, "I should have opted for the smaller LED fixture."
The elevator is going up.

There is a law of diminishing returns. I have 600w in a 4x4, if I use much more than 80% I get light stress.

True Story.
I bought two UpDayDay LED fixtures for a 5 x 10 tent.
Later I happened to be invited into a grow op that was using the large Gavita and another brand. My lights look like toys compared to those Gavitas and another brand. The buds they get are also much larger, quality louder. That's not to say UpDayDay can't grow buds because yield is tempered by environment/grower
I think it's better to have more and turn down then too little and get spindly garf. But there are many factors. The hydro shops by me sometimes have used so there might be options for any budget.

And you can raise them a little higher, run them full blast for that deeper penetration the lady's like....
