It may even be listed in this great post (I didn't want to go through the entire thing again :jointsmile but it's all about lumens per square foot. You want to calculate the area that your plants canopy will be able to occupy... then figure out how many combined lumens you are pushing (this means USABLE lumens, so your lights need to be the correct distance away to maximize potential).

Then divide your total lumens by your area = lumens/sq. foot

I think around 2,000 is the minimum suggested for actual growth... then as you increase, your potential will increase. Once you go above 6,000 you are pretty much in the vigorous growth range. It's all relative though. You have to make sure you can manage heat as you increase the total amount of lights. So you want the maximum lumens/sq. foot... as long as your temperatures are under control. Some people have to sacrifice some lumens for better climate conditions.
