The cheapest way you can make that happen is to go to Lowes and get 2 48" shop light kits. They have everything you need.You just need to build a canopy to house them. I have a 45gal and a 55gal and both have this lighting setup. The shoplights should be less than $10 each = $40 and the buls are between $5-$10. I use two 48" 40watt Gro Lux & two 48" 40watt 6,500K. You can get both bulbs at Lowes also. Just look for the plant and aquarium bulbs and then read descriptions to find Ultradaylight 6,500k bulbs. Here is a link to my rate my tank

That should help you decide. My plants grow nicely.
I leave them on 12 hours a day and use all Seachem ferts.
Seachem ferts include: Flourish, Potassium, Iron, Trace, & Excel.
Good luck hope I helped
