Don't trim that driftwood!
Have you thought about an open top tank with your light either hanging from anchors in your ceiling or on a stand? Then if you have a green thumb along with your green toe, you could attach a plant or two that can live with roots submerged and foliage above the water. Look into pothos, heartleaf philodendron, creeping fig, syngonium, peace lily, fittonia, any of the pileas, draceana sanderiana, dieffenbachia, Chinese evergeen, sweet potato vine, purple crinkle plant.
Either way, that is a great piece of driftwood, you should get some shrimp for the tank.
