Bejay is right. If you want to expand your grow area, use the set up you have now for propogation and vegging and get some good light for your new box. If you go 4'x4', you want a 1,000 watt light. (Some people might argue that you can use a smaller light. Well, you could, but, if you want to take full advantage of your grow space, 1k is what you need.)

PharmaCan Reviewed by PharmaCan on . Almost done my first grow, time to revamp setup? 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? Rating: 5
