Right now im growing with 10x 26 watt CFL's (17,000 lumens), 3x 12v computer fans for ventilation, and a box that's about 1.5x6x6 feet.

Would yield greatly improve if I implemented mylar around the entire thing, and made a new box with centralized light like 4x4x6 feet?

Is 17,000 lumens enough? Or should I add a couple more CFL's? Should I add another fan?
