A quick search of the net yielded only one decent high return investment option:

1. High Pressure Sodium Lamp (600 watt is the most efficient but a 400 watt may suit a smaller space).
2. Fan running 24 hours a day if possible and oscillating.
3. NFT tank with pump and spreader mat (these come with the tank), Rockwool cubes.
4. 24 hour timer to control light periods. This should be used with a high power switch known as a contactor or relay switch as grow lamps can easily burn out regular timers used on their own.
5. A pH tester to test water and nutrient feed solutions.
6. pH adjuster such as phosphoric acid to adjust water and feed solution to around pH 5.2 - 6.0.
7. Nutrients, ones aimed at growing the plant you want to cultivate are best.
8. Matt white paint or white plastic to cover the walls of the grow space.
