What answer lies in that thread. I dont have time to look thru 200 pages my man. If have a specific post you would like to me read. Ill be happy to check it out. But Im not even going to attempt to read all that stuff.
But on page 1 that information by keef trees seems to be on par with my opinion regarding the purpose of defoliation.
