Pallet gardening, perfect for gardening within a small space. Always take advantage of empty vertical space--it will leave your balcony or patio looking clean, not cluttered. I frikn love stuff made of pallets!
Use an old pallet to make a vertical herb garden! Cheap, easy and beautiful! Just make sure to find out how the pallet was treated so you're not planting in harmful chemicals! And- u can write the name of the herbs on the wood!
