I made a stand for my 75 gal. fish tank. Used 2 x 4's doubled and across. 4 ft. long x 2 ft. wide. I used the new T-8's shop lights. They are brighter and cheeper to use. I used them where I used to work (before retireing). My plants loved them. I installed those 4 ft. wall mirrors across the back side to increase the light to the plants. On sale for $5 each. I also bought a 2 ft. x 2 ft. mirror for the ends. Made a nice boxed in area with the front open for viewing. Don't know if I will use a rolled up plastic sheet for the front or not.
