Depending on how big your budget is, you could go to a hardware store and find yourself some OTT-Lites. They're made specifically for indoor plants, and although they're about 10$ a bulb, they do work marvelously.
My plant's about 4-5 inches tall and bloody growing as if it life depended on it. I've been using minimal nutes and otherwise watering it about once every 1.5 days.
Just be carefull with heat and ventilation. if you're growing in a closed box, or in any box, a fan with a hole won't cut it. I learned that the hard way.
