Thank you, I can always appreciate someone who wants to learn more! I am going to search my academic databases for some more studies that pertains to this matter when I have time Rick, being I am about to start school back myself. I wouldn't dismiss the credibility of mindphuck's article so quickly though. One academic study is less credible than five, but still credible. I doubt Dr. Clarke had any biases in his research about how he thinks cannabis should produce thc, that would be silly, and furthermore unintellectual of him. Your suggestion of waiting for the buds to become fully mature, as opposed to starting the last week, intuitively seems problematic too. It seems as if once the buds have already fully matured then they would start declining. I don't see how the non-existence of light would interfere with this declination, being it's part of cannabis' natural life cycle. Also, no one is implying that the light period is significantly more important than the dark period, just the fact that it is significant.
