For a square space, you may want to consider a Mars II. A 700 would fill that space nicely and produce great quality buds. You want about 35-50 watts/square foot. A 700 in that space would give you about 48w/sqft. That will work perfect in your area and give you great penetration.
Thx for your Help! 2 -3 from these not enough
