Ok to add some actual academical background comments.....
The article extract that was posted is a little misleading in how it reads but you also have to read it with the correct frame of mind! It does clearly state that no evidence of wind having an effect could be shown however mechanical stimulus (in this case mechanical flexing) did have an effect and it always does have an effect to some degree or other. The article also clearly divides "wind" into two distinct categories or properties, that of the mechanical flexing and of the airflow actually on the plant material. When it later refers to the airflow having a negative effect on the plant don't confuse this as meaning wind in general, it merely means the physical action of airflow over the plant! In these experiments the plant would have been tied so as to not allow the air to cause a mechanical flex.
I can't be arsed to look back through the list of posts but whoever it was that said wind has no effect couldn't be more wrong, full stop. Thigmomorphogenesis is a definite real non-imaginary reaction to stimulus, wind being a good example of suitable stimulus.
However, whether the effects of a fan are beneficial or not.... I'm not experienced enough growing MJ to know!
And it's real late so sorry if that sounds garbled LOL
but obviously I dunno what im talking bout... 2 ozs
