well itll cost you a bit over a dime t start up, I can guarantee that! You will need lights, an HID for flowering if you want results, depending on wattage and maker, that 70 (70 watt security light) to 400 bucks or so, a sunsystem/hydrofarm 1000 watter with a nice hood. Thisll be the main purchase, I would recomend a 150 or 250 watt HPS system for what this will be.
