Anyone who has tried defoliation for themselves knows that the pictures in that article that say "4 days later" where the plant goes from no bud to full of bud are clearly falsified.
In veg, chopping off all fan leaves makes a plant take twice as long to get to the same size as leaving all the fan leaves intact.
In flower, chopping off all fan leaves greatly reduces yields.
This happens because of both the stress of hacking at the plant and the plant losing it's "solar panels".
The more posts I read from the guys who support it, the more "defoliation" definitely seems like a troll tactic, getting dummies to chop off all their fan leaves, ruining their plant(s).
And the guys who are against defoliation all seem to have tried it for themselves and come to the same realization.
Also, after skimming parts of that article and very easily spotting blatant spelling mistakes, arguments that consist of quotes from fictitious growers the writer "has spoken to", and then reading the "about the author", it seems like that article was written by icmag's version of finshaggy.
That's not a good thing.
