New grow room Grow room setup

Hi
I have a 4x12x8 place to grow. I will be growing white widow auto. I have 6 300w (147 true wattage) led full spectrum. The walls are painted flat white. How many plants can I grow at once for this space.

I would see if u could fit 4 4x4 trays

i know u said 8 ft and that would smash u in there but would be nice to get 4 trays

You are going to have to give us more information. How are you planning to grow and what sort of time scale are you looking at? At either end of the spectrum you could veg out trees and only keep four plants or you could go Sea of green and grow 4 plants per square foot.

How could he fit 4 4x4 trays in a 4x12?

Guestimating you can light up a 6x4 space with those lights you have, much more than that and your light levels are going to be too low.
You could grow anywhere from 1 plant to 16 plants in a 4x4 space. Excluding crazy set ups (full SOG)
I used to grow 12 plants perpetual in an 8x4 where 4 plants are in early flower, 4 in mid flower and 4 maturing. Now I have lowered the plant count and only do 4 plants per 4x4 area. But I have plenty of light. Your lights are going to be your limiting factor not your space.
