I am growing in a closet 28" x 56"...roughly 2 1/2 ft by 4 1/2 ft. I'm using a 400w HPS light. I have 7 plants roughly 36" tall. The space is full...completely. I keep my lights 6" to 12" above the "sea of green". I'm just wondering if I should be pruning a bit to let the light penetrate better and let more of the light to the areas with the better buds. I started 12/12 10 days age so I can id all the potential good buds. Thanks
