Plants do best with 10,000 lumens to each plant or more. The old rule of thumb is 50 watts for every sqft but in truth that is still a little low but works.

18/6 light cycle is fine it saves a little money on the power and gives the plant a little rest. There is no measurable difference between a plant vegged at 18/6 and under 24/0 light. Advanced nutrients answered this question many years ago under lab conditions.

A 250 watt HID will illuminate a 2' x 2' garden.
A 400 watt HID will illuminate a 3' x 3' garden.
A 600 watt HID will illuminate a 3.5' x 3.5' garden.
A 1000 watt HID will illuminate a 4' x 4' garden.
