I need to know more about your room, How you intend on growing your plants (natural, topping, 12/12 from seed, LSTing), and how many people are you planning on growing for. You can grow new plants ever 3-4 months.
Only go florescent if you want low heat and cheap. But if you grow florescent, you have to keep your plants short through LSTing or 12/12 from seed.
HPS would be your best option for lighting. The initial cost is more, but your yield will be way higher. You can let your plants grow taller, and the bottom buds fill out more.
Lemme check prices real quick.
