So Mr. Farmer I am not understanding what you are saying. With my new thinking I am getting a 400 hps. In the top left, the inline fan sucking out, top right filter. So my air on the inside is getting sucked out starting from the filter, through light, then out the back. How will I get fresh air in? And Mr. Farmer do you move your light up and down? And if you do, do you have any problems with the air tubing you have hooked up to your light when you move it up and down?


ps Great looking box real grade A setup.
