Growing three White Widow or Royal Kush. I was thinking about using this http://www.hydroponics.net/i/133316 . In a 6x6 closet with a floor drying fan will I be alright or should I buy multipule lights for vegging/flowering? I know that may be a stupid quetion. New grower here.

Alright man thanks I want to eventually move up to 6 when I really know what I'm doing but I'd like to know since yours is smaller should I have a higher wattage?
