Sorry if that came across the wrong way. I was trying for a light hearted, 3rd grader level come back. I guess my attempt at humor fell kind of flat.
The ‘wisdom’ I was referring to is the whole idea of using lights as any kind of metric for comparing one grow to another grow. Gram/watt and Gram/fixture both.
I’ll stop clogging up your thread and bow out.
I run air atomized aeroponics. The root chamber is full of air, and roots, and a few million very very very small droplets of water. Its just the single chamber for the entire tent. I have had anywhere from one to three plants growing in it at one time. 
I dont want to mess up Joe’s thread any more. If you want details, click on my name and look for my recent threads. Or do a search for aeroponics and they will show up.
