This diagram is in Discount-hydro.com 's current catalogue. It shows growroom lighting and spacing for a 10 foot by 10 foot space with 400 watt, 600 watt and 1000 watt lights respectively. My budroom isn't nearly this size--it is 4' x 4'--so I would cut the number of lights in half, but this may be a good basis for discussion.
