What’s a good number of plant in a 5 x 5 with a 1k watt LED?

Yeah that depends on your style. 25 clones in a sea of green, 2-4 plants and a scrog. Depend on the strain you choose as well. Big ol hairy longleg sativa's need lots of room.
Best part is you get to choose. Have a blast.

Make sure it’s true 1000w led. Makes a huge difference if it’s pushing much less from the outlet

It’s a evo10 from ac infinity. Not sure what watt it is other then what they have labeled

What’s your yield?

I use to do 8 in a 4x4, but now prefer 4 in my 5x5. Although I was able to grow 5 in there this past summer, and all landrace Sativas.

I did 9 plants and works well but I think I could do 12 plants with my 5x5 tent next season.

Depends on the strains I suppose but I've got ~3lb before

When you say short veg, how long you talking bout?

As long as it takes really. Couple weeks. Maybe 2-3. Depends how fast the plants grow. I do alot of training and trimming

I like to have some space for me getting in so generally I'm using 4x5 I get 6 in comfortably, if I was using it all I'd grow 4 big uns or 9 smaller/medium sized
1/3 weeks veg depending, yeild is strain related some of the best plants won't yeild much over 100/125g (ime)

I think I mentioned in another thread that light has a hot spot. It cranks out a lot of light but you'll want to raise it and/or keep stuff out of the center of the light pattern.
Check the 12"PPFD map. Center mass is 2kµmol and then values roll off very quickly so you really can't do much with that light at that height. But it you look at the 18" map, the gradient is better. We see that behavior in all LED lights - as hang height increases, light falloff, as a percentage, decreases and that's good because you want an even canopy and an even light cast.
How do things look at 18" and turn the power down to, say, 60%. The values just off center will be about 50% of the values at 100% power so you're going to be near 1kµmol near the center, which is very high unless you're running CO2, but you'll still be getting 700'ish near the corners.
When I was thinking about that, I was seeing 4 plants in the tent. You've got 25' to deal with but knock off a few that you can't use in the center so…22 sq. ft. Four plants will give each of them a bit over 2' on each side and that's good room to grow in.
I don't have experience with equipment this size. I grow in a 2' x 4' but only grow one plant, which fills the tent, but I do favor high light, meaning I grow at or close to the light saturation point (800-1000µmol). That's a "maximum yield" approach.
Please do this…"For the children!"
You've dropped a grand on that light and it's a beast of a light. Spend a little moola on a light meter. A PAR meter will set you back at least $400 (I wouldn''t buy any of the cheaper ones) but a Uni-T Bluetooth light meter will be $32 very well spent and it is, in practical terms, as accurate as a $600 Apogee.
I put together the attached PDF to give some background on why a lux meter can be used and how to use it to figure out PAR.
