How many dwc buckets under 1000w leds?

[lincon1231]

im building a 12 900w led light dwc grow room.
Im not sure if i should use 4 5 gallon buckets or 6 5 gallon buckets under each light
in my last grow, im using a chinese made 900w led
the light covers about an 4.5x4.5 area

also
Im thinking, in dwc, it takes 4 month from clone to harvest since we are growing in the same bucket in the entire grow
then if im growing just auto strains. I get almost the same amout of yield but finish in 3 month
Im just asking cause i pulled about 650-700 grams dry buds in 6 auto plant under 1 led
2 plants finished in 70 days and some took a bit longer to finish.
will i get moe buds in a long run?
Growing autos cost a bit more electricity each month and more on seeds
but compare to the yield in a month shorter time
it seem like i will harvest more in a long run

I'm trying to figure out what you want help with. Sounds like a basic math problem.

I use soil but there is no way to answer your questions. If you are growing autos you could fill that space with 4 or 6 or 8. Are you gonna train them? Are you growing something small like a low rider or something huge like lemon og? I personally go for fewer plants and train them to fill the space. Others grow like a sea of green and grow as many plants as will fit. And the answer to yields depends on your skill with each type of plant.
