It,s size of grow area.
I,ve seen flood tables ,with one inch holes cut in styrofoam with one inch rockwell cubes hold 100 plants .
They flip after 6 or 7 days veg.
Then on other hand we had tunnel greenhouse 80ft. long ,,14 ft hugh ,16 ft. across only hold 22 plants.[big plants

In doors I find 1000 hps will throw 1 pound with 8 bigger plants or 30 small one .Better set ups will throw more.
I have friends who since getting med. permit have never worked again.
Just think if dutchman had buddys who got his clones ready for him
