That sounds like a fairly good amount of lumen output for the size of your area. Also, based on the size of your area, your plant can't possible be that big. If your plant isn't that big, your roots probably aren't that massive either. Smaller roots = bigger buds. Thicker stalk = more nutrient uptake. Bigger Roots + Thicker Trunk + Bigger overall plant = Huge Buds. I'd say your buds are coming along very nicely for a small sativa dom. plant grown under roughly 10,000 lumens using CFL's.
