You're wrong, I can. How do you suspect we all calculate lumens per square foot? You add up the lumens from all your lights and divide by the area of the room.

You're right that if the lumens are coming from multiple lights, you can arrange the lights to hit all parts of the plant, which is nice.
smoknjoe Reviewed by smoknjoe on . My first grow, Whats up yall, I've been around for a few months mainly reading, keeping a low profile, and doing my best to learn all that I can. About a month ago, I got up the courage to start a grow. I'm not sure what strain I'm growing. I just took some seeds I had lying around, germinated them and put them in some miracle gro brand soil. I guess I'll give a few stats on my closet/growroom: - 4ft wide (I'm using 3ft of that) - 2ft deep - 5ft tall - Currentlly I have 2 cfl's putting out 2900 lumens Rating: 5
