Hey, I have my two fixtures hanging on an angle to light my plants that are arranged 'stadium style' with the tall in the back (against the side-lighting T5s) and the short plants in the first row and the middle plants...in the middle. The plants don't mind as long as they get the right amount of light and heat. My grow area is just sheets of cardboard painted white and hung around the plant area. Easy to put up and take down, just like a bedoin tent. I use these 1'x2' blocks of styrofoam I picked up for free when I need to have the grow off the floor like when they are seedlings. No cabinets to build. Just fasteners in the ceiling to tie things to.
