One thing I see missing, which should increase yields are reflective panels.
I use portable/movable reflective panels made from 4x8 sheets of 1/2" (pink or blue) foam insulation covered with mylar. These panels have chains attached to the top. Place J hooks on ceiling around perimeter of space. These panels can then be removed for access and adjusted vertically. The J hooks can be placed at diff spacing as well to keep panels as close to plants as possible. Since the mylar wont blow around fans can be directed beneath or between panels.
This will provide up to 30% more light, which will either allow for a bigger grow space oer more intense light on the periphary.
Also a really good idea if your grow isn't taking up the entire room
