That is certainly not what I said about Jorge and RC Clarke, I didn't suggest in the slightest that they don't know anything.
You posted a quote and video from Jorge where he says that there is science behind what he is saying about not pulling off leaves, I'm just asking to see this science?
You and others have posted in here that you will only believe peer reviewed scientific papers, so can we see these scientific papers regarding cannabis defoliation that have convinced you that it doesn't work?
With regards to RC Clarke here is the article in question:
If these inhibitor-laden leaves are removed, the plant will proceed to flower, and maturation will be accelerated. Large leaves shade the inner portions of the plant, and small atrophied floral clusters may begin to develop if they receive more light.
In actuality, few if any of the theories behind defoilatin or de-leafing give any indication of validity. Indeed, leafing possibly serves to defeat its original purpose. Large leaves have a definite function in the growth and development of Cannabis. Large leaves serve as photosynthetic factories for the production of sugars and other necessary growth sub-stances. They also create shade, but at the same time they are collecting valuable solar energy and producing foods that will be used during the floral development of the plant.
Premature removal of leaves may cause stunting, because the potential for photosynthesis is reduced. As these leaves age and lose their ability to carry on photo-synthesis they turn chloro tie (yellow) and fall to the ground. In humid areas care is taken to remove the yellow or brown leaves, because they might invite attack by fungus.
During chlorosis the plant breaks down substances, such as chlorophylls, and translocates the molecular components to a new growing part of the plant, such as the flowers. Most Cannabis plants begin to lose their larger leaves when they enter the flowering stage, and this trend continues until senescence. It is more efficient for the plant to reuse the energy and various molecular components of existing chlorophyll than to synthesize new chlorophyll at the time of flowering. During flowering this energy is needed to form floral clusters and ripen seeds.
Removing large amounts of leaves will interfere with the metabolic balance of the plant. If this metabolic change occurs too late in the season it could interfere with floral development and delay maturation. If any floral inhibitors are removed, the intended effect of accelerating flowering will be counteracted by metabolic upset in the plant.
Removal of shade leaves does facilitate more light reaching the center of the plant, but if there is not enough food energy produced in the leaves, the small internal floral clusters will not grow any larger. Leaf removal
may also cause sex reversal resulting from a metabolic change.

Can you see what I mean, he doesn't seem 100% sure when it comes to specifics about defoliation. I do understand that this article was written in 1981 so there might have been experiments done since then to prove/disprove the claims that he is making.
I also noticed that his first paragraph there is this line "Large leaves shade the inner portions of the plant, and small atrophied floral clusters may begin to develop if they receive more light.", but you're saying this does not happen as buds don't need light to grow?
I'm genuinely interested in seeing the evidence that has convinced you that defoliation doesn't work, as I find it quite an interesting subject.
