Did you actually read his posts in the previous thread?
He showed up and quickly started insulting anyone who mentioned that they had some experience growing. The prof is all over the place, threatening to leave, deciding to stay, acting like a martyr while proclaiming to have won medals of honor... And you wonder why people were pissed off?
The prof is only happy when he is on top. That is apparent. He does not belong here. He actually thinks that his shit is somehow special while using KISS but not divulging it because he is not going to give it away for free although that is his only goal (of at least 3 he listed) in life...
The guy is lost... He was important once, an expert. But now there are alot of experts with growing skills equal to or better than his and he cannot cope with that while promoting his website and non-existent video that he will share with everybody but not for free....
And BTW, you are not helping this thread by starting another opinion war on the subject.
