No, I really didn't get the point at all.

Are you saying that a little indirect light is ok? All my experience would say that you are 100% wrong and are additionally spreading misinformation to potentially ignorant growers. I have had a minute light leak that delayed flowering 3 weeks and also caused hermies where there were none before as well as dramatically lowered yield. Your "proof" is laughable. Until you have flowered 2 of your chambers side by side with a variety of strains, one in low indirect night lighting and one in absolute dark can you even start to say that you have proven anything. Until then, keep your "information" to your stoned self please.
