I am wanting to run 4k watts in a 9x13 grow room. I will have a mini 2 ton mini split and 4 large 1k adjust a wings. I currently use a 9x9 room with 2k watts scrog style, ebb & flow system 2.5 gal and 12-15 plants. Will this new setup be efficient or worth it (jumping from 2k watts to 4k and only gaining 4 extra feet)?
