New to indoor growing and am trying to determine which light would be sufficient for a 6X3 foot grow room. I am interested in the Son Agro 430W HPS bulb which has an added blue spectrum to the bulb. It has 53000 lumens, which at the recommended 2500 lumens per square foot ratio, would be enough light for 21.2 feet squared. However I keep seeing on here that a 45000 lumen light is only enough for a 3X3 foot area, that is actually 5000 lumens per square foot, so which is it. Also if it helps, I plan on doing a scrog grow, and using a 4 or 6 ft light mover. I know a light mover is a good tool for reducing shaded as well as hot spots, but how much additional light coverage do you actually think this yields. Thanks in advance for help, and I know I put a little bit of info into one posts, so if any clarification needs to be done, I'm ready for it.
