I am going to get this light with Hortilux Bulb Upgrade. In am not growing in a closet or room without vents so do I need this? System IX Ballast Upgrade and last, I know I can veg and flower with a Horti but would it be better to flower with 1000 watt Sodium Backup Bulb if I can afford it or is the Horti all that is needed?

Is this EconoGro System good? and does anyone know where I can find it or one just as good for less?
